Kimchi is the national food of South Korea. Almost every household in Korea has this spicy fermented vegetable dish stored in their kitchens. It is becoming popular in the West and is now available in many American supermarkets. If you are new to kimchi, you may wonder if kimchi is better hot or cold.

You can eat kimchi either hot or cold. It depends on your taste and the dish you are making. But according to researchers, cold or slightly warm kimchi has great probiotic value. If you heat the dish too hot, it may kill the beneficial bacteria. 

In this article, I will talk about eating cold and hot kimchi, and about different ways to eat both. First, let’s learn how people usually eat this traditional food in Korea.

How Kimchi Is Usually Eaten?

The people of South Korea have been eating kimchi for over two thousand years. The key ingredient of kimchi is traditionally cabbage, but people also prefer scallion and radishes. They mix the fish sauce with the brine and also add:

• garlic
• ginger
• chili pepper

Finally, the brine full of vegetables is fermented at a cool temperature for a few days. This process helps to grow probiotics that have many health benefits. Moreover, fermented vegetables can be preserved for a long time like this. 

Therefore, South Koreans eat kimchi daily, not just for its spicy and crunchy taste but also for its health benefits. Koreans have at least five different dishes for every meal, and on special occasions, you will see at least ten dishes. They prefer spicy side dishes to add flavor to other dishes, and one is always kimchi!

Kimchi is a staple food of Korea, as it is always served with other dishes in almost every Korean household and restaurant. People also like to eat kimchi as a snack, but it is mostly served with rice. Kimchi’s tangy flavor can also enhance the taste of many other dishes, so people include it in making:

• soups
• porridge
• pancakes
• rice cakes

Is Kimchi Better Hot or Cold?

As you can see, kimchi is a part of the everyday meal of South Korean people. Many people all over the world have also started to appreciate the unique spicy taste and health benefits of kimchi.

Kimchi is fermented at a cool temperature, and most people prefer eating it cold and do not want to put extra effort into heating it before every meal.

On the other hand, some people prefer to heat kimchi before meals. However, the health benefits and taste of kimchi can change when you heat it. So, let’s see the pros and cons of eating cold and hot kimchi. 

Eating Cold Kimchi 

Kimchi is a dish that is full of:

• minerals
• vitamins
• antioxidants

It is also rich in vitamin C and K, which helps blood circulation and keeps bones healthy. All these health elements are intact in cold kimchi, and it is full of healthy bacteria or probiotics. 

Also, the taste of cold kimchi is actually its true flavor. It has a tangy and spicy taste, which goes well with other dishes. Here are the benefits of eating cold kimchi:

1. The fermentation process of kimchi grows probiotics, which are good for our digestive system. We know the lactobacilli bacteria in kimchi as good bacteria, that ensure healthy digestion.
2. The healthy bacteria of cold kimchi reduce gastrointestinal problems and can help colon inflammation and irritable bowel syndrome. 
3. Eating cold kimchi can also improve your immune system. The healthy bacteria of the kimchi minimize inflammation caused by various diseases. 
4. Probiotics in cold kimchi are great for boosting immunity to ward off common viruses.
5. Cold kimchi has a sour and spicy flavor, and it is crunchy. Hence, many people love to eat it this way. 

There are not actually any cons to eating cold kimchi. However, some people might find the taste of cold kimchi too sharp. So, they heat it to reduce the pungent taste. 

Eating Hot Kimchi

Many people prefer eating kimchi hot. The good bacteria will die if you heat kimchi for too long, but it will still have nutritious value. 

Here are some reasons to eat hot kimchi: 

1. Many people do not like to eat cold foods and kimchi is no exception.
2. If you dislike the sharp taste of cold kimchi, you can heat it or microwave it to reduce the sharp taste. 
3. You can add hot kimchi to different foods to add a smokey or barbeque flavor. 

As you can see, eating hot kimchi is all about changing the taste. It does not contain the full health benefits of cold kimchi. Cooking kimchi will kill the bacteria, so there will be no probiotics. Also, do not go over 70 degrees while cooking kimchi because it will impact the taste. 

Although you can lessen the sharp taste of kimchi by heating it, the smell gets stronger. Once kimchi is heated, it needs to be eaten within a few days. Reheating hot kimchi will also destroy the unique flavor. So, heat kimchi in small portions and eat it as soon as possible.

If you compare the nutritional value of cold and hot kimchi, you see that eating cold kimchi is better than eating hot kimchi. If you prefer to eat kimchi for its health benefits, then eat it cold. Otherwise, you can eat it hot.  

Tips for Eating Cold and Hot Kimchi

There are many dishes for which you have to heat kimchi with other ingredients, and there are many dishes where cold kimchi is a perfect fit. Here are a few tips for eating cold, and hot kimchi with different dishes to get the best taste:

• Mix kimchi with soup and cook it. Or you can eat it cold with soup. 
• Eat cold kimchi with rice to get great taste and probiotic benefits.
• To make fusion dishes add cold kimchi to a salad.
• Kimchi kimbap tastes better with slightly warm kimchi.
• Cabbage kimchi, radish kimchi, and onion kimchi can be eaten hot or cold. But you cannot heat cucumber kimchi, it will destroy the taste.
• Adding fried and hot kimchi to tofu adds a smoky flavor. You can also put hot kimchi in a burger for the same taste.
• The bibimbap rice dish is a famous Korean dish, and only cold kimchi goes well with this dish. On the other hand, hot kimchi also goes well with dolsot bibimbap. 

Conclusion  

Is kimchi better hot or cold? People eat kimchi not just for its flavor-enhancing power, but for its nutritional value. Therefore, it is recommended to eat kimchi cold or barely warm to get the probiotic benefits.

• Which Fermented Foods are Best for Your Gut?

Kimchi is a Korean dish that is a spicy fermented mix of vegetables. Fermenting is an effective preservation method, so you might wonder, does kimchi go bad? 

Kimchi can go bad. If you keep kimchi at room temperature after opening, it’ll last about a week. Kimchi stays fresh for a much longer time if you refrigerate it. It will remain fresh for three to six months or more but will continue to ferment and taste sour. Refrigerate your kimchi below 39 degrees F to reduce the speed of spoilage. 

There is so much to learn about kimchi, such as:

• how to prolong its shelf life,
• how to make it
• how to tell if kimchi has gone bad

Keep reading to learn all the answers you need about kimchi! 

How Long Does Kimchi Last?

Kimchi is a Korean staple dish and has been for generations now. It’s easy to see why it’s a superstar in the kitchen. The flavoring in kimchi is intricate, but the recipe is relatively easy. It’s a harmonious and versatile dish that’s rich in nutrients and flavor. 

Kimchi is originally from Korea and staple to both North and South Korea with a broad appeal, rating five stars in the nutrition scorecard and various uses. Kimchi is made with:

• cabbage
• garlic
• other vegetables
• fish sauce
• salted seafood
• chili powder
• spring onions
• ginger

You’ll taste a plethora of flavors once it hits your tongue!

Kimchi can last months before it spoils. The shelf life of kimchi doesn’t have a specific and straightforward answer. A Korean kimchi veteran might say that kimchi doesn’t spoil. Instead, it merely ripens. However, it won’t taste the same forever as it is made with fermented vegetables. 

As kimchi is not pasteurized, the bacteria in it are alive. So fermentation is ongoing with kimchi, and it’ll become sourer with time. 

If you’ve bought kimchi from a store, you’ll have to look at the expiration date to see if it is okay to eat. Usually, the shelf life of store-bought kimchi is between eight and twelve months. 

There are several variables in the equation, like time or whether you’ve opened the kimchi yet. Temperature also influences the fermentation and makes the kimchi sour. If the kimchi is sitting in a warm spot, the fermentation rate will accelerate. Store a fresh jar of kimchi in the fridge right away after buying. 

It’s also tricky to answer how long kimchi may last in the fridge after opening. A prolonged lifetime depends on:

• how long it was stored before opening the jar
• the temperature
• how sour you like kimchi

If I had to estimate it roughly, I’d say kimchi should taste fine between six months to a year after you open it. This calculation applies if you’ve refrigerated the jar after first opening, and it didn’t taste very sour. 

It’s also worth mentioning that if kimchi is pasteurized and unopened, you can store it for a couple of months in the pantry. Unpasteurized kimchi tastes best before a month.

NOTE: These are only rough estimates and are applicable for the best quality kimchi only.

How to Tell If Your Kimchi Has Gone Bad

To tell if your kimchi is safe to eat or not, you’ll have to look for possible spoilage signs. Some people throw away good kimchi because they think that it’s a lost cause. Read the signs below. If your kimchi looks like this, don’t panic because it should still taste fine and be safe to consume. 

1. It’s not unusual for kimchi to explode upon opening. It may happen from the gas buildup during fermentation. This event is not unlike a champagne bottle popping off due to an excess build-up of gas. 
2. If kimchi seems bubbly after opening, it should be fine. Bacteria are alive inside, so the kimchi might be fizzy and active. 
3. It’s safe to eat the kimchi you’ve kept at room temperature for an extended period. It might become very sour, but you can add it to a soup or stew if you prefer. Or, throw in some other vegetables instead of eating it raw. 
4. If the cabbage turns soft after storing kimchi for a long time, don’t panic. It’s perfectly fine to eat it. But if you don’t want wilted cabbage, try using the kimchi in a recipe. 

Look out for visual signs to tell if kimchi is spoiled. If you spot mold or a white film on your kimchi, you can scoop the mold part off the top and a layer underneath, or you can discard the whole dish just to be careful. 

If you see mold on your kimchi, it’s already begun spoiling. Some people are comfortable eating food where mold has been scraped off. However, molds can make you sick, so there is a risk. 

If your kimchi smells sour, it should still be safe to eat. But if it smells off besides just sour, discard it.

If you are still unsure whether you should throw away your kimchi, you can do a pH test on it. According to BBC, kimchi’s pH level should be 4.5. If it is ever more or less than that, throw it away.

If the kimchi is too sour for your taste, or the vegetables are not crunchy enough, you can mix it with stews or use it in stir-fries. It’s up to you when it comes to kimchi that tastes sour, your options are to:

• keep it
• throw it away
• use it in a recipe

Mistakes That May Spoil Kimchi Faster

There are things that can go wrong when making kimchi, especially for beginners. The radish might taste bitter, or the cabbage could be too:

• thick
• thin
• fibrous

If the kimchi turns out too bitter or salty, next time try brining the vegetables more or less, depending on the issue. 

Sometimes, kimchi turns out slimy which is undesired. When unwanted microorganisms outgrow the beneficial ones, kimchi spoils and gets slimy. It might be safe to eat, but it will taste strange, have a weird texture, and won’t be enjoyable. So you’ll need to consider some factors to avoid this outcome. 

1. Too Much Salt: Back in the old days kimchi was packed with salt before it was widely known that salt is bad for high blood pressure. Excess salt can make kimchi taste funny. 
2. Too Much Flour Paste or Rice: Rice flour paste is not essential to make kimchi, and too much of it will undoubtedly spoil your kimchi. 
3. Temperature: Prepare kimchi at the right temperature. The optimal temperature for fermentation is around 68 degrees Fahrenheit. Add more salt and monitor it closely if the temperature exceeds 72 degrees Fahrenheit. 
4. Too Much Sugar: Be careful with how much sugar you put in kimchi, especially the salt ratio. Korean restaurants typically use artificial sweeteners because excess sugar tends to make kimchi slimy.

Additional Kimchi Tips

Ensure that there aren’t air-filled gaps and bubbles after putting the kimchi in a jar. Too much air inside the container will make unwanted bacteria grow, and the kimchi will taste off. It will also produce unevenly seasoned and fermented kimchi. 

It’s best to pack and press it all down firmly so that you’re leaving as little space as possible, using a fermentation pounder like this from Amazon can really help. Do leave space at the top of the jar to cover the vegetables with brine. Seal the lid tightly and do not leave the jar out for too long without refrigerating. 

Store the jar for a few days at room temperature, and it is essential to keep it away from sunlight. Only move the jar to the refrigerator once it has started to taste a bit tangy. The cold temperature will slow down the fermentation gracefully.  

How to Store Kimchi for Longer Shelf Life

By now, you already know how the temperature influences kimchi when it comes to storing it. You can keep unopened kimchi in the fridge or pantry. Leave kimchi that’s not sour enough at room temperature for a couple of days till you get the desired taste. It’s best to store the kimchi in the fridge once you have opened it. 

Kimchi doesn’t have a stable shelf life in general because it has live bacteria. As a rule of thumb, immerse the ingredients in the brine every time you open it and seal it again. 

Additionally, use clean utensils to handle the kimchi inside the container. Otherwise, it will encourage dirty bacterial growth and cause the kimchi to spoil. Try to open the container as little as possible to avoid exposing the kimchi to the air, risking unwanted bacterial growth. 

If you used a large container for storing your kimchi, you should consider dividing it up into smaller portions and placing them in smaller jars to preserve them.

NOTE: You can sort the portions out according to weeks, making it easy to keep track of them.

The bottom line is, you can increase kimchi’s shelf life if you:

• limit the opening and closing of the jar
• use clean utensils
• immerse the kimchi in brine

How to Make Kimchi

Kimchi recipes vary from one region and season to another, but you can keep the dish entirely vegan using plant-based ingredients. Kimchi is sold on Amazon, is available in stores, and is comparatively inexpensive. If you ferment kimchi at home, it takes a while. 

Kimchi can be eaten as:

• an ingredient in a recipe
• a dip
• a side dish

Additionally, kimchi can be made to preference with flavors that are:

• sour
• spicy
• sweet

Napa cabbage is the main ingredient in kimchi, with other vegetables like:

• Korean radish
• carrots
• cucumber
• scallions

Kimchi is not a tricky dish to make, but if it’s your first try at fermenting vegetables it might feel overwhelming. Fermentation isn’t a conventional way of cooking. After all, it is rotting food! The only difference is that you’re in control of the rotting.

Here are a couple of recipes for making kimchi. The most widely used recipe is the one that uses napa cabbage. Before you begin, here are some things to consider during fermentation. 

1. I recommend keeping a jar at room temperature to speed up the fermentation process and store the rest in the fridge. You have to do this for a few days before you put it in the refrigerator.
2. Ideally, use an airtight container like a mason jar. Sanitize the jar first, and fill it so it has 1/3^rd space left so the jar doesn’t explode. 
3. It’s working if you notice bubbles in your kimchi. Check it by opening the jar over the sink every few days for a quick sniff test. You can stir it around a bit but ensure that the vegetables are always submerged in the liquid. 
4. The pH of the kimchi won’t be 4.5 until two weeks have gone by. So don’t panic if it’s not at this level. 

I recommend eating it after a month and within three months of preparing it. 

Napa Cabbage Kimchi Recipe

The following recipe is an altered version of a Maangchi Easy Kimchi made with napa cabbage. Before you begin, I suggest you watch some instructional videos, particularly by Maangchi.

Ingredients 

• 2 lbs napa cabbage 
• 5 ½ tsp sweet rice flour
• 3 Tbs salt 
• 1/2 cup water 
• 1 ½ tsp sugar 
• 1 tsp ginger 
• Four garlic cloves (large)
• 4 ½ tbsp onion 
• 3 tbsp fish sauce 
• 4 tbsp Korean hot pepper flakes (for tasting)
• 2 Green onions 

Instructions to Make Kimchi

Firstly, trim any undesirable leaves off the cabbage. Then remove the cores and cut the cabbage into quarters lengthwise. Chop the quarters into bite-size pieces. 

Rinse and drain the cut pieces of the cabbage thoroughly. Use a colander (sold on Amazon) to drain the cabbage and place it in a large bowl. Sprinkle it with salt, and let it rest for 30 minutes. 

Next, mix the cabbage, salt it again, and let it rest for another thirty minutes. Repeat this step one more time, for a total of three times with thirty minutes in between. It should take about one and a half hours. 

During the thirty-minute intervals, prepare the rice porridge. Mix the sweet rice flour with water in a small saucepan. Keep mixing until it boils and continue until the porridge begins to bubble, which should happen after about five minutes. 

Pour the sugar into the pan and continue cooking until the mixture seems translucent. Now, let it sit and cool. Make the kimchi paste while the porridge cools. In a food processor, mix these ingredients until smooth:

• garlic
• onion
• ginger
• fish sauce

Pour the mix into a large bowl, and add the cooled rice porridge and hot pepper flakes to the bowl. Mix it thoroughly until it is a consistent paste and combine the cabbage and other vegetables in the mix. Everything should be well coated by the time you finish mixing. 

Fill the jar up to 3/4 of the way full with the kimchi mix and store it in the fridge for a month to let it slowly ferment, and check it regularly. 

Korean Radish Kimchi 

This is a simple kimchi to make. It’s called Kkakdugi in Korean, which means cubed radish kimchi. Typically, people enjoy this dish in chilly winter weather. It’s firm and crisp and tastes slightly sweet and peppery. 

The main steps are:

1. Cut the radish into cubes.
2. Salt it.
3. Mix the seasonings.

Ingredients

• 3 large Korean radish 
• 1/3cup coarse sea salt
• 3 to 4 scallions 
• 2/3 cup Korean red chili flakes 
• ¼ cup salted finely minced shrimp 
• 2 tbsp fish sauce 
• 1 tsp grated ginger 
• 2 tablespoon sugar 

Radish Kimchi Instructions 

First, clean the radishes using a scrub brush like this one, or scratch the stubborn impurities off with a knife. If necessary, peel the skin. If the skin is smooth and clean, use them with the skin on. 

Next, cut the radish into an inch-thick disc and further chop them into one-inch cubes. Place the cubes into a large bowl. Don’t worry if the discs are large, they will shrink when you salt and ferment them. 

Sprinkle the salt over the radish and make sure that the salt coats the radishes evenly. Let it rest for about thirty to forty minutes until the radish cubes have expelled some liquid and softened. 

While it sits, prepare the seasoning. Use the rest of the ingredients mentioned above and mix well. Set the mixture aside so that the chili peppers become pasty and dissolve. 

Drain the radishes in a colander without rinsing. In a large bowl, mix the seasoning and scallions with the radishes by hand until the seasonings have evenly coated the radishes.

You can taste the seasoning to see if you need to make any changes. It should taste too salty, and the radishes should be dry by now. Next, add the salted shrimp or fish sauce. 

Like the previous recipe, repeat the storing process and remove air pockets from the jar. You can keep it at room temperature for a day, depending on how fast you want the kimchi to ripen. Then, put it in the refrigerator and eat it after a week. It will keep its excellent flavor and texture for several weeks! 

Tips On Eating Kimchi 

Kimchi is a special dish because it’s packed with flavor and rich in nutrients. However you cook your kimchi, the process and basics are the same. 

Here are some bonus tips that will make kimchi taste even better and make your kimchi-making skills more mature. 

Tip #1: Kimchi is Seasonal

Kimchi is a seasonal dish, and its recipes vary from one region to another. Basic napa cabbage kimchi is a fall dish. You can experiment with other vegetables according to the seasons. For example, in spring, try fresh greens, and during summer try radishes and cucumbers. 

Tip #2: Experiment with Flavors

The second tip I have for you is to experiment with flavors and different ingredients. Embrace the seasonings because it’s one of the most fundamental properties of a kimchi dish. Broaden your range with seasonings and add-ins. Also, kimchi is typically spicy, so you can dabble with that too! 

Tip #3: Use Salt Wisely

As I’ve mentioned before, too much salt can ruin kimchi, so use salt wisely. A saline environment will also speed up the fermentation process. Don’t use iodized table salt as iodine can block fermentation. Your best bet is to use coarse sea salt. I recommend salting in a couple of steps: 

1. Rub the vegetables with salt to open and break them.
2. Soak them in a brine solution for more enhanced flavors.

Tip #4: Pack and Store Kimchi Carefully

Make sure not to disturb your kimchi often, and store it very carefully, as I’ve directed above. Pack the kimchi in and always use an airtight container to store it.

Tip #5: How to Serve Kimchi

In Korea, kimchi is served with almost every meal and used as an ingredient to prepare dishes like jjigae, a traditional stew. Additionally, it’s also used to flavor pizza and noodles. The recipes above are two of the most basic recipes for kimchi. You can experiment with other vegetables and keep the process the same. 

Conclusion 

Kimchi has become a regular guest on the menus of restaurants and home dining. It’s delicious and ample with vitamins and minerals. During fermentation, it will develop complex flavors and nutrition. It will last a long time and is easy to prepare. 

So to answer the question: Does kimchi go bad? I would say it ripens rather than spoils. It’s naturally a sour and pungent-smelling dish, so unless you see visible molds and it smells weird, it’s safe to consume. Kimchi is quite beneficial for health and has survived the test of time. In essence, kimchi is living history!

Fermentation is a method of preserving food that has been used by people since ancient times. As this is a food preservation method, you might be wondering how long fermented food lasts. Does fermented food go bad?

Fermented food can last 3 months or more if kept in a cool and dry area in sealed containers. This timeline can vary based on what type of food has been fermented. It is possible for over-fermentation to occur and spoil the food. 

There is a lot to learn about fermentation before beginning. In this article, you’ll learn all you need to know about the:

• shelf-life of fermented foods
• signs fermented food has gone bad
• how to prevent food spoilage

The Shelf Life of Fermented Foods

The shelf-life of fermented foods varies depending on the type of fermentation and other factors that affect the fermentation process. 

Fermentation is an age-old method to preserve foods that have been used by people for generations. In recent years, fermented foods have also become very popular, mainly due to the health benefits it offers.

To state the entire fermentation process in simple words, it is a process of preserving food by culturing specific strains of yeast or bacteria into the food in a controlled environment. Unwanted and harmful mold, yeast, or bacteria can’t grow in the food, and it will last longer as a result.

There are common ferments around you that you might not notice. For example, yogurt which is fermented milk. Milk will last a week at best after opening it for the first time. On the other hand, yogurt can last at least two weeks before it gets spoiled.

Predicting how long fermented foods will last before spoiling is a challenge. There are simply a lot of variables that control the outcome of fermented foods. If everything is in ideal condition, here are some examples of the shelf life of some fermented foods:

#1: Fermented Alcoholic Beverages

Homemade alcoholic beverages are fermented with a yeast-based culture. Examples:

• beer
• wine
• cider

Typically, they last longer than other fermented foods. The fermentation becomes alcoholic as they age, and bacteria and yeasts can’t survive in an alcoholic environment.

Homemade beers normally have a shelf life of around four months.

Ciders might need to be refrigerated immediately after bottling to slow down the carbonation process so it will last longer. Usually, homemade ciders are at their finest state during the first four weeks after bottling.

The longer a wine ages, the better its taste will be. Always store homemade wine in cold and dark places. It’s best to let the wine age at least one year before drinking. Usually, wines have a shelf life of five years if stored under ideal conditions.

#2: Shelf-Life of Fermented Vegetables

Vegetables become very acidic as they ferment, and most of the harmful and unwanted bacteria can’t survive in an acidic environment. As the ferment ages, the vegetable will become much softer and more acidic. 

Cucumber pickles and sauerkrauts are known for their long fermentation time. And if the fermentation is good and stored at the proper temperature and in a dark place, they can last up to one year before getting spoiled.

NOTE: Wondering what the difference is between fermenting and pickling, and which is better? Read my article to find out!

Pickled vegetables’ shelf life depends on how you want to eat them. As mentioned before, pickled vegetables become softer and more acidic as they age, and also have changed:

• color
• texture
• taste

Most fermented vegetables can last six to twelve months, depending on the:

• vegetable type
• ingredient quality
• storage environment

Unlike sauerkraut, kimchi tastes best within three to five days of fermentation but can be stored for up to one year in the refrigerator.

These ferments can be stored for up to six months in the freezer before going bad:

• hot sauce
• salsa
• chutney

#3: How Long to Keep Miso

Miso is another fermented food that tastes better with age. Good miso is aged for at least one year and should be stored in the refrigerator once it’s opened to prevent it from spoiling. 

#4: Naturally Fermented Drinks

Examples of homemade fermented beverages that have a decent shelf life are:

• water kefir
• kombucha
• Jun

If stored in a refrigerator, they can last up to six months. But as they age, they taste more sour so enjoy them while their taste is great.

Factors That Determine the Shelf Life of Fermented Foods

As mentioned before, there are many factors that directly affect the process of fermentation. Some of them are given below:

#1: Fermentation Temperature is Important

Temperature is the most important factor that influences and has a direct effect on the fermentation process.

If the weather is hot, it will speed up the fermentation and decomposition process. On the other hand, a colder environment slows down the fermentation and decomposition of foods. This is why it is extremely important to store fermented foods in cold and dark places to maximize their shelf life.

#2: Salt Level in The Brine

Another factor that determines how long fermented foods will last is the salt level in the brine. If it is too low, it might speed up the fermentation process, and shorten the shelf life of the ferment.

If the salt concentration in the brine is high, it can significantly slow down the decomposition process.

#3: The Acidity Level Of The Ferment

All types of fermented food become acidic as they ferment. The acid level keeps harmful and unwanted molds and bacteria from growing, helping to preserve the food.

#4: Anaerobic Environment For Fermentation

Yeasts, molds, and bacteria grow rapidly in an oxygen-rich environment. The main point of fermentation is to inhibit the growth of harmful:

• yeasts
• molds
• bacteria  

For good fermentation, keep oxygen away from fermented foods and keep them submerged in the brine solution.

HOT TIP: Airtight jars are best for fermentation.

How to Tell If Fermented Food Is Spoiled

Has your fermented food gone bad or not? It’s easy to identify by observing some common signs, some you can tell just by looking. Here are some common signs of spoiled fermented foods:

#1: Discoloration Of Fermented Food

To identify spoiled fermented food, first carefully visually inspect the color of the food. Older fermented foods might appear a bit cloudy but are still ok.

If you notice anything that is not normal like a bright green cucumber turning black or grey, then there is a good chance it has gone bad.

This type of discoloration indicates that the food became contaminated during the fermentation process, and should not be eaten.

#2: Check for Mold or Yeast Formation

During the entire fermentation period, make sure that the fermenting foods are submerged in the brine and stored in a jar with an airlock like this sold on Amazon. This prevents the fermented foods from coming in contact with oxygen, which can trigger the growth of toxic mold and bacteria in the ferment.

Any mold is a sign that your fermented food is contaminated. Typically, molds are spotted on top of the food or on the lid of the jar, because bacteria can survive on salt brine. 

If you see mold, toss that batch of fermented food away and thoroughly clean and sanitize the jars before reusing them.

Sometimes you might notice a fuzzy white substance on fermented food that can be mistaken for mold, but is actually a yeast formation known as “Kahmâ€. They can be spotted on the surface of fermented foods and are not harmful to human health. 

The Kahm yeast can be scraped off of the surface and the ferment can be eaten as normal. Although, you need to keep an eye on the ferment as it can come back easily.

#3: A Bad Smelling Ferment

Check if the fermented food is bad or not by the smell. Fermented foods go bad mainly because of harmful bacteria, which produce a very bad smell. In some cases, the smell will be so foul that you won’t be able to withstand it.

The harmful bacteria release gases which is the source of the foul smell in your fermented food. If the smell lasts long even after keeping the jar open for a while, the food might be contaminated. 

Over-fermented foods can stink, but it doesn’t mean that they are bad. If you notice that the smell is different than normal, then there is a problem with the food, and throwing it away is a good idea.

#4: Foul or Weird Tasting Ferment

The last sign of bad fermented food is a foul taste. If the taste is somewhat off or is not the usual taste, then there is a good chance that the ferment has spoiled. In this case, it is not a good idea to eat it.

Is it Safe to Eat Spoiled Fermented Food?

It is not safe to eat fermented food that has spoiled. The main reason for eating fermented food is the health benefit it provides. Fermented foods can help improve digestion and boost immunity.

It is not recommended to consume spoiled fermented food since it can cause health issues. Fermented foods go bad mainly due to harmful bacteria growth and when consumed can cause food poisoning.

How to Prevent Fermented Food From Going Bad

Below are some things that you can do to prevent fermented food from going bad:

#1: Properly Clean and Sanitize Fermenting Equipment

It is essential to clean and sanitize the jars thoroughly before starting any sort of fermentation, especially when preparing to brew beer or wine. 

First, wash the jar thoroughly with hot water and dish soap. Use a brush to get rid of any particles inside the jar, then rinse it with tap water. This is enough cleaning to ferment vegetables. 

For brewing alcoholic fermented drinks, some extra cleaning and sanitizing is necessary. Once the jar is cleaned using the method mentioned above, soak it in bleach water. To do that, pour one tablespoon of bleach into a large bowl and fill it with water.

Then simply submerge the jar entirely into the bleach water and soak it for a few minutes. Then, rinse it with tap water. Bleach will kill all the bacteria in the jar. 

#2: Use Good Quality Ingredients

Always use the best quality ingredients. If there is anything wrong with the ingredient like a portion of the vegetable is bad, then cut out the bad portion and get rid of it.

Store-bought vegetables can contain preservatives like chlorine. Supermarkets do this to keep the food fresh for a longer period. Avoid supermarket foods for fermentation, because the preservatives will hinder the growth of good bacteria during fermentation and lead to spoilage.  

This is why you have to be very selective about the ingredients used to ferment. The best way is to buy organic ingredients directly from farms. Also, wash and clean the vegetables thoroughly before fermenting.

#3: Maintain The Right Fermentation Temperature

While fermenting, keep a close eye on the temperature. If it is too warm, it can speed up the fermentation process, and the ferment will be slimy. 

On the other hand, if the temperature is too cool, it can slow down the fermentation process significantly. What usually takes seven days will take more than ten days if the temperature is too low.

The ideal temperature for fermentation is between 65-72 degrees Fahrenheit. During summertime, maintaining this temperature might be a bit tough. Keep your fermentation jar in a cold and dark place, like in the basement at that time. 

#4: Brine Strength is Important

The strength of the brine is also one of the factors that affect the shelf life of fermented foods. The salt brine strength should be such that no harmful bacteria can grow in the jar. Most fermentation recipes recommend a 2-3% brine solution relative to the weight of the ingredients. 

For some vegetables, the required salt concentration for successful fermentation can increase up to 5%. So, whatever recipe you are following for your fermentation, make sure that the salt concentration is within the recommended limit. 

NOTE: Always keep your ingredients submerged under the brine. This will significantly decrease the chance of spoilage.

#5: Avoid Chlorinated Water

Chlorine is used as a cleaning agent that kills almost all types of bacteria strains in water. This is what makes chlorinated water unsuitable for fermentation purposes.

If you use chlorinated water for fermentation, it will kill all the bacteria during the fermentation process, whether good or bad. 

Also, chemically treated water contains strains of bacteria that can withstand chlorine. If this type of water is used, then harmful bacteria will grow during fermentation, and the fermented food will go bad.

This is why you should always use filtered water that is free from any type of chemical or contamination during the entire fermentation process. By doing so, you will be able to create a high-quality brine solution that will be able to keep your fermented food safe for a long time.

Conclusion

Fermentation is an easy way to preserve various types of food. To prevent spoilage, before fermenting make sure to:

• clean and sterilize everything properly
• avoid chlorine-treated water
• maintain a suitable temperature

If you just started your kombucha journey, but have heard some horror stories about its potential to explode, understandably you might be a bit nervous about it! Is there a way to prevent a kombucha explosion in your kitchen? What makes kombucha explode in the first place?

Kombucha is not likely to explode in the fridge as cool temperatures slow down or even completely stop the fermenting process. The only way kombucha will explode in the fridge is if the brewer does not take a few factors into account, like the quality of the bottles used.

Kombucha goes through an extensive fermentation process in order for it to get to a place where it’s ready to consume and enjoy. Are there dangers to be concerned about when making homemade kombucha?

Can Kombucha Explode?

You might be surprised to hear that kombucha can actually explode. Sugar and yeast fermentation builds up so much more pressure than standard fermented vegetables, which can be dangerous.

NOTE: To learn more about fermenting vegetables, read my article on how to ferment ANY vegetable with success!

The bacteria and yeast in the kombucha culture convert the sugars in the sweet tea into a mixture of:

• lactic acid
• a tiny amount of alcohol
• a large amount of carbon dioxide (CO2)

Sometimes the amount of carbon dioxide is a bit too much, and this can cause a kombucha explosion.

Once the fermentation has begun, it does not stop on its own without outside help from you. Unless you slow down the fermentation process, it will simply continue. This means that the kombucha fermentation will keep producing carbon dioxide nonstop until the sugar is exhausted. 

Carbon dioxide can cause a considerable amount of pressure on the kombucha container. If you do not take a few proper precautions, the pressure can cause an explosion as the gas has nowhere to go.

Can Kombucha Explode In The Fridge? 

Kombucha will most likely not explode in the fridge as it is quite sensitive to colder temperatures. The fermentation process usually slows down or completely stops as the temperature drops. 

However, still keep an eye on the kombucha when it is in the fridge, especially if you haven’t released the carbon dioxide from the bottles before placing them in the refrigerator. 

As the fermentation process slows down, it does still produce some carbon dioxide in a lesser amount until the process stops completely. 

The new carbon dioxide will join the rest of the bottle and can even cause a significant amount of pressure on the bottle, which could still cause the bottle to explode in the fridge.

Although kombucha exploding in the fridge is usually caused by factors that the maker did not take into account, it must be treated on a case-by-case basis.

How To Prevent Kombucha From Exploding

There are some ways to prevent kombucha from exploding during the fermentation process. These few tips are useful in ensuring that you get the full harvest of kombucha tea and keep all your bottles intact at the same time.

Tip #1: Burping The Bottles

One good way to help prevent an explosion is to do something that is called burping the bottles. This allows some gas to escape from the bottle, which in turn releases a noticeable amount of pressure from the bottles too. This can prevent an explosion from occurring.

To burp kombucha bottles, loosen the caps of the bottles just enough to let air come out. This will release the pressure in the bottles while allowing for the fermentation process to continue at the same time.

HOT TIP: Most seasoned kombucha makers will advise that you burp your bottles every day or every other day while your kombucha is fermenting. 

Tip #2: Refregerate the Kombucha

Refrigerating kombucha can also prevent the bottles from exploding. As mentioned above, kombucha will stop the fermentation process when it is kept at a cold temperature. This stops the fermentation process from making too much carbon dioxide.

If you like a specific amount of flavor to your kombucha, refrigeration will also prevent the flavor from changing so it will turn out just the way you like it.

Tip #3: Use Quality Fermenting Equipment

Use quality glass fermenting bottles (I like these ones on Amazon) or containers to ferment kombucha. If the bottles are strong enough and you leave enough space at the top of the bottle, then this will help prevent the bottles from exploding.

Tip #4: Keep Kombucha in Ideal Temperature

Just as cold temperatures can slow down or even stop the fermentation process, on the other side of the scale, warm-to-hot temperatures can speed up the fermentation process. This causes excess pressure on the bottles and could cause an explosion. 

The ideal temperature to ferment kombucha is between 75 to 78 degrees Fahrenheit. This will ensure that the fermentation process does not go too fast or too slow, keeping it at a manageable pace so the brewer can keep up.

Tip #5: Don’t Add Too Much Sugar

Do not add too much sugar to the kombucha, especially during the second ferment. Adding too much sugar will make the yeast work double time. This will produce more carbon dioxide, and put pressure on the bottles, even if you put the bottles in the fridge.

Tip #6: Leave Headspace in The Bottles

When bottling kombucha, make sure to leave one to two inches at the top of the bottle. This will leave some space for carbon dioxide to be stored without putting pressure on the bottle.

NOTE: If you follow these tips, they will help prevent exploding kombucha bottles and the sticky mess that comes with them!

Is Your Kombucha Carbonated Enough?

To carbonate kombucha, you will need to do what is called a second ferment. This involves placing the kombucha into airtight bottles and adding sugar to them, in the form of:

• fresh fruit pieces
• fresh fruit puree
• regular plain sugar

Then seal the bottles and let the fermentation begin.

NOTE: Some carbonation can occur in the first fermentation. However, most of the carbonation happens in the second fermentation.

If you do not want to go through the whole fermentation process again to carbonate the kombucha, then the good news is you don’t have to! Flat kombucha has the same health benefits as fizzy kombucha so you won’t miss anything if it’s not carbonated.

Is there such a thing as getting too much fizz, though? The answer is not really as long as you use the right amount of sugar during the second ferment, then you do not need to worry about over-carbonating your kombucha. The fermentation process will stop naturally once the food source (the sugar) is finished. 

If you are having trouble with your kombucha not being carbonated enough, then there are a few things that can help get it bubbling.

Stir the kombucha before you bottle it to loosen the yeast from the bottom of the container. This will help evenly distribute the yeast in the bottles to ferment them properly.

Also, ensure that you dry the bottles properly once you have cleaned them, as this will ensure that there is a good seal on your bottles.

Do not burp your bottles too often, as this will release the carbonation from the bottle and could cause the kombucha to be more on the flat side.

These few tips should help you get the kombucha carbonated just how you like it. 

Conclusion

Kombucha can explode due to many causes, and it is necessary to watch out for this phenomenon when making kombucha since an exploding bottle can be messy and dangerous.

In some cases, refrigeration may help the kombucha to not explode and can be beneficial in keeping the flavor to your liking.

If you are careful and use the right equipment, and follow a recipe from an expert to the tee, then you should be able to avoid an explosion in your kitchen or fridge.

• Can You Second Ferment Kombucha With Jam?
• Can You Ferment Kombucha in Plastic?

It is exciting and fun to experiment and make homemade kombucha. It only takes two essential pieces of equipment to make it, a brewing container and a cover. The material of the container chosen to ferment the kombucha can impact its quality.

It is not recommended to use plastic containers to make kombucha, because plastic is easily damaged. Scratches or marks on the container can house bacteria, and plastic can release harmful chemicals that can sabotage the kombucha SCOBY.

There are two fermentation processes to make kombucha, and plastic containers can only be used temporarily for one of the processes. When choosing a container, consider the size of the opening and the jar’s capacity. There are other pieces of equipment that can be purchased to make kombucha, but it is not essential.

Is It Safe To Make Kombucha In Plastic Containers?

It is highly recommended not to use plastic containers to make your kombucha, mostly during the first fermentation process. There are many reasons why plastic should not be used, which include:

1. The plastic releases chemicals, like BPA, into the mixture that can destroy the kombucha. The Symbiotic Culture of Bacteria and Yeast (SCOBY) can be damaged by the chemicals released from the plastic because they are very sensitive. This is very important in the first fermentation.
2. Plastic can be damaged easily with scratches and marks where bacteria can easily sit and grow. 
3. The amount of time the kombucha sits in the plastic container and how often the plastic is used will also have an impact. During primary fermentation, the container will be used for 6-10 days. 

Over an extended period, the plastic will get damaged from the acidity and release harmful chemicals. This increases the more it is used so it should be avoided.

If you really prefer plastic containers, it’s best to use one meant to brew wine, you can purchase one on Amazon. The plastic used in these containers can handle acidity better.

HOT TIP: It is highly recommended to never use cheap plastics when brewing kombucha.

You can consider using plastic containers temporarily for the second fermentation period only. It is not as harmful due to the change in acidity and SCOBY concentration in the kombucha during this stage.

TOP TIP: Learn all you need to know about flavoring kombucha in my full guide!

What Containers Should Be Used To Make Kombucha?

When making kombucha, it is imperative to select the right material for the container you use because it can impact the brew’s quality and flavor. It can also affect the person’s health who will be drinking it because chemicals or harmful bacteria may leach into it.

These are the best materials to use to make kombucha:

#1: Glass Containers

Glass is the best material to make kombucha because it can’t get damaged easily or scratched where bacteria can live. Glass does not release harmful chemicals that damage the kombucha, or react to the acidity of the blend, which is why it doesn’t wear and tear as quickly. 

These glass containers are well-priced on Amazon and are simple to purchase. You can also find them in many different shapes and colors. With these glass jars, you can see the process of fermentation nicely as the kombucha brews. 

For a continuous brew system, it’s best to get a larger jar with a spigot with a tap on the jar used to pour the kombucha, like this one from Amazon. It is vital to get a spigot made from: 

• food-grade plastic
• stainless steel
• wood

HOT TIP: Avoid containers made of cheap plastic or metal as this can destroy the Kombucha SCOBY. 

#2: Ceramic Containers

To ferment kombucha in a ceramic container, choose one made with a food-grade glaze inside the jar, like this one from Amazon. It is essential to have a glaze that doesn’t contain lead that can damage the kombucha and be unsafe for consumption.

A ceramic jar is an excellent choice if you would like to use a continuous brewing method. This type of container also looks really nice on the kitchen counter!

#3: Porcelain Containers

Porcelain jars are safe to use for making kombucha. It is crucial to make sure the glaze is food-grade to prevent any contact with lead. Porcelain containers that are not food-grade, such as vases and decorative pottery, should be avoided.

#4: Oak Barrel

An oak barrel like this one on Amazon can be a lovely container to use as it looks quite fancy! Using an oak barrel impacts the flavor profile of kombucha with a unique woody flavor, which is very tasty. 

What Should Not Be Used to Make Kombucha

Some types of containers are not recommended for brewing kombucha, as they can damage it. It is useful to know what these are to make sure they are avoided. These include: 

1. Plastic should not be used at all for the first fermentation, as discussed above. 
2. Crystal jars should not be used as they contain lead that can be harmful to the kombucha.
3. Jars made of metal should be avoided because metal containers can be detrimental to kombucha.

NOTE: The only metal that could sometimes be considered for brewing kombucha is stainless steel jars since they are strong and cannot be damaged easily. They are expensive but easy to clean and safe to use. Glass is still preferred.

Can Plastic Containers Be Used In The Second Fermentation?

During the second fermentation process, there are a few containers that you can consider to store your kombucha. In this stage, it is crucial to choose an airtight container that can close properly to ensure that the brew will maintain its carbonation. 

The best kind of container to use for the second process is glass, as it is the most resilient and reliable for both stages. I recommend glass flip-top bottles with a plastic lid, like these sold on Amazon. If you cannot purchase glass bottles or do not get them in time, you can also try leftover store-bought kombucha bottles or bottles that have already been used for other drinks. 

What Containers Can Be Used For Second Fermentation?

Sometimes we are not able to get the correct containers in time, or they are just too expensive. Here is a list of different bottles (some found on Amazon) you can use as a second option:

• Wine bottles: a cork or wine stopper is needed to seal them correctly. 
• Already used store-bought kombucha bottles. 
• Plastic soda or water bottles. 
• Beer bottles that have been cleaned and a lid will be needed for these. 
• Beer growlers. 
• Mason jars with plastic lids. If they do not have plastic lids, then wax paper can be used between the lid and jar. 

Before using any second-hand or already used jars, it is crucial to ensure all jars or bottles are cleaned and dried correctly and not damaged. Make sure the lids close adequately to ensure it is airtight to facilitate carbonation. 

You can use plastic jars if you need to in the second fermentation process, but remember they are still not the best option. Plastic bottles can be used for a short period in the second fermentation. Since the SCOBY is removed it reduces the damage to the plastic that releases harmful chemicals. 

If you decide to use plastic, it should only be used for a short period until you can purchase the correct bottles. It would be best to use plastic bottles only once because the more they are used, the more damage occurs.

Conclusion

Kombucha is a healthy drink with probiotics. The type of container used to make it can impact its contents, glass is best used for both primary and secondary fermentation.

Other important things to consider are the size of the container and its volume because these impact the rate of fermentation. 

A container cover is also needed when making kombucha for the first fermentation as it helps protect it and the SCOBY. There are many options to use as a cover, and other supplies can be purchased but are not vital to have.

• Can Kombucha Explode in the Fridge?

Even though you can drink kombucha after the first fermentation, most people generally opt for a second ferment. Why do people second ferment their kombucha, and does jam work to flavor the kombucha during the second fermentation?

You can use jam to flavor your kombucha during the second fermentation process. You will need to know the sugar content of the jam to make sure that there is enough to feed the yeast so the kombucha can ferment adequately.

Kombucha is a very healthy drink filled with minerals and probiotics. Filled with health benefits, some people drink kombucha in place of sugar-filled sodas. To replace soda in your diet, it is recommended to second ferment your kombucha, but why is this the case?

Second Fermenting Kombucha With Jam

You can most definitely use jam as a flavoring to second ferment kombucha. Use your favorite jam, or if you have multiple bottles of kombucha to second ferment, use a different jam for each bottle to have a variety of flavors to choose from.

HOT TIP: If you are using a brewer’s bottle like these on Amazon, make sure that the jam is not so chunky that it can not fit through the opening of the bottle as they tend to have small bottlenecks.

If your jam is chunky, use a fork to mash it up a bit to make it smoother. Make sure there is enough sugar in the jam to feed the yeast. This ensures that the kombucha can ferment adequately and make the right amount of carbon dioxide that is essential for fermenting and carbonation.

If you are not sure about the sugar content in your jam, put a little bit of extra sugar into the jam and mix it around so it is evenly spread. Then add the jam to your kombucha. 

Method To Second Ferment Kombucha

You have completed the first fermentation of your kombucha, and it tastes good, but you decide that you want to experiment and try your hand at a second ferment. Where do you start?

NOTE: If you’re wondering how long to ferment kombucha, read my guide.

Make sure you have all the equipment and ingredients you need for the second fermentation process. These can all be found on Amazon, and include:

• good quality glass bottles
• coffee filters or cheesecloth

If you are flavoring the kombucha, then make sure to have your flavoring close by. If not, then make sure you have some sugar close by.

First, filter the kombucha with a coffee filter or a cheesecloth to remove any dead yeast that is floating around from the first fermentation. Some yeast will die during the second fermentation too, but filtering before the second ferment will reduce the amount of dead yeast in the final product.

Secondly, fill the glass bottles with filtered kombucha. If you are flavoring your kombucha with anything, then leave some room in the bottle. If you are not flavoring your kombucha, then you can fill the glass bottle, leaving about one inch of space between the lid of the bottle and the kombucha.

Leaving this space will help prevent the kombucha from exploding as there is enough room in the bottle for the extra carbon dioxide produced during fermentation. 

Once the kombucha is in the glass bottles, add flavoring to the kombucha. If you are not flavoring your kombucha, then at this stage add in some sugar. Stir the kombucha to spread the sugar or flavor throughout the liquid. 

Then close the bottle as tight as you can and let the kombucha ferment. This should take about three to seven days at room temperature. However, this timeframe may vary depending on the temperature of your kitchen, keep an eye on it.

You can burp your kombucha every few days if you feel the need to. This can help prevent the kombucha from exploding, but it could also affect the carbonation, so the kombucha may not be as fizzy.

Once the second fermentation is done, move the bottles into a cold storage place, you can place like the fridge or a basement. The sole thing that is left to do is enjoy your kombucha!

Why Second Ferment Kombucha?

Now that you know how to second ferment kombucha, here is why you might want to and if it is really necessary.

It is not necessary to ferment your kombucha a second time. You can drink it and get the same benefits from it after only one fermentation. Some people choose to second ferment their kombucha as this carbonates the drink, making it nice and fizzy.

You can also flavor kombucha without fermenting it a second time. So, if you aren’t a fan of carbonated drinks, you can still enjoy flavored kombucha.

Kombucha that has been through a second ferment can satisfy those trying to replace soda with a healthier drink. It has a lovely fizz and taste with added health benefits and way less sugar.

Can You Second Ferment Kombucha With Honey?

If you don’t want your kombucha flavored or don’t want to use regular sugar, you can use honey in the second fermentation process.

Honey has more than enough sugar in it to feed the yeast in the kombucha properly to begin the second fermentation.

You can also add in other flavors that go with honey, such as mint and lemon, to make a delicious kombucha without any extra sugar.

Other Flavours You Can Second Ferment With

We have spoken about jams and honey, but there are many other flavorings you can put into kombucha in the second ferment.

These are some other flavorings you can use to flavor your kombucha with:

• Fruit juice, freshly squeezed or store-bought (will need extra sugar or honey)
• Fresh fruit
• Frozen fruit
• Syrups, like maple syrup
• Vanilla beans (will need extra sugar or honey)
• Dried fruit (will need extra sugar or honey)
• Coffee (will need extra sugar or honey)

These flavor combinations work well together in kombucha: 

• Lemon and lime
• Triple Berry – usually strawberry, raspberry, and blueberry, but any berries work
• Lemon and ginger 
• Cranberry and ginger
• Apple and cinnamon
• Strawberries and basil
• Lavender and chamomile 
• Pineapple and coconut

Conclusion

You can make kombucha with jam and honey as well as with a whole lot of other flavors. Kombucha is a very versatile drink that can be flavored or not, and carbonated or not, and can be made to suit everyone’s tastes.

Kombucha is:

• an excellent alternative to sodas
• really good for you
• packed with minerals and probiotics

Plus, it tastes good!

One can generally keep unopened tins of canned biscuits for extensive time periods before they go bad. Naturally, you do not want to consume canned biscuits that have gone bad. It is important to determine if canned biscuits have gone bad so you know whether or not they are safe to eat.

Unopened canned biscuits can go bad depending on how much time has passed since the expiry date. You can still eat the canned biscuits if it has only been a few months since the expiry date. Prepared canned biscuits generally last 3-5 days after being baked. However, if the biscuits have changed color or texture or have a funny smell, it is best not to eat them.

It is pertinent that you are able to tell if canned biscuits have gone bad as this will help prevent illness from consuming expired food. Exploring ways to prevent canned biscuits from going bad can be beneficial in enjoying the biscuits for longer and minimizing the risk of falling ill from consuming expired biscuits.

Wondering if miso soup can go bad? Check out this post I wrote on how you can tell!

Signs That Baked Canned Biscuits Have Gone Bad

Here are some spoilage indicators to look out for when determining if the canned biscuits you have prepared have gone bad or if they are still safe to eat.

Sign #1: The Biscuit Color

Once the canned biscuits are prepared, they are likely to be a golden color. 

Due to the fact that canned biscuits are pastries, you can expect the mold that grows on canned biscuits to be similar to that found on expired bread, which is generally green and white in color.

If you find that the biscuits have changed color or have any hint of mold, then it is likely that your canned biscuits have gone bad.

Sign #2: Check The Biscuit Texture

Canned biscuits are known for their fluffy, light texture. If you find that your biscuit texture has changed to the point where it is extremely hard, then the biscuits are stale. 

While this may not be as pleasant to consume, it does not mean the biscuits have gone bad. Stale biscuits can still be eaten without concern that you will fall ill, but they are likely to be a lot less tasty than fresh, canned biscuits.

Alternatively, you may find that your canned biscuits have become soft and soggy, which is an indication they have gone bad. It is best to throw away the canned biscuits if they have become soft and soggy.

Sign #3: The Biscuit Shape

When you prepare canned biscuits, they are likely to come out round and raised in the oven. However, if they are extremely flat, it might be a sign that they have gone bad. However, if the biscuits have only flattened slightly, it is not a cause for concern and they are likely still suitable for consumption.

It is advisable to take caution if the biscuits were originally round and tall and have now become rather flat. When determining this, it’s important to factor in how the canned biscuits were stored and for how long.

Signs Your Tin of Canned Biscuits Have Gone Bad

Here are some spoilage considerations for when you are determining if your canned biscuits have gone bad or whether you can still eat them.

Sign #1: The Color of Biscuit Dough

When opening a fresh tin of canned biscuits, you can expect to find a dough that looks:

• white
• smooth
• creamy

Take caution if the canned biscuits have any brown or pink tones that do not resemble their usual color. 

If you notice any unusual color or detect any hints of discoloring, it is quite likely that the canned biscuits have gone bad and are not safe to consume.

Sign #2: Look for Mold

A fresh tin of canned biscuits will generally have a smooth texture. Any changes to the texture of the biscuits could indicate that they have gone bad. 

Additionally, it is also possible that the canned biscuits have mold, which usually presents as green and white in color. If you see any mold, it is best to throw the can of biscuits out.

Sign #3: Smell The Biscuits

While unprepared canned biscuits do not have a distinct smell, the presence of an unfamiliar or strange smell is a good indicator that something is off.

If the canned biscuits give off a rancid odor when you open them, it is best to not risk eating them and throw them away.

Important Considerations When Determining If Canned Biscuits Are Ok to Eat

Here are some things to keep in mind before consuming canned biscuits that are expired or you suspect have gone bad.

#1: How The Biscuits Were Stored

The canned biscuits label generally indicates that they should be stored in a place that is:

• cool
• clean
• dry

If the unopened canned biscuits were stored in extremely hot or cold temperatures, they are likely to go bad in a short period of time.

Once prepared, the biscuits should be stored in an air-tight container (this one is a good value on Amazon) to maintain freshness. Keep them out of the sun, in a cool, dry place like a cupboard or in a kitchen countertop corner.

The container should not be stored in the fridge since it can make the biscuits soggy. However, if you freeze and defrost the biscuits, they can be eaten for 3-5 days as long as they are stored properly afterward.

#2: The Condition of The Tin of Canned Biscuits

Tins can easily be damaged. Sometimes they get damaged on the car trip home or are handled within the house. If the canned biscuits tin has been dented or severely damaged, the biscuits could be damaged too.

Be sure to assess the biscuits upon opening to determine if the biscuits appear ok to eat despite any damage displayed on the exterior of the can.

#3: Biscuits That Were Frozen, Defrosted, and Reheated

If the biscuits were initially prepared, frozen, defrosted, and subsequently reheated, It is likely that the biscuits will only be suitable to eat for 3-5 days after:

• initial preparation
• freezing
• defrosting
• reheating

While freezing the biscuits allows you to store them for long periods, the same principles apply as if you had just made them and they will only be edible for a few days before they start:

• flattening
• growing mold
• smelling bad

#4: Number of Days Since the Biscuits Were Baked

Once canned biscuits are baked, they become perishable goods. This means that they are only suitable to eat for approximately one week after being prepared, provided they have been stored properly.

NOTE: If not properly stored, they are likely to go bad in less than a week.

How to Store Canned Biscuits

Here are some guidelines and tips regarding how to store canned biscuits to keep them fresh and useable for as long as possible.

Tip #1: Store in a Cool, Dry Place

Store canned biscuits in a cool, dry place in your cupboard or pantry. Keep them out of direct sunlight as it can cause the canned food to go bad, or even explode as a result of the excessive heat. 

Similarly, storing your cans in extremely cold places like the freezer can cause the can to swell. The damp conditions of fridges and freezers can result in the seal breaking or the metal lid corroding, resulting in contamination and spoilage.  Freezing canned biscuits may result in the can rusting or bursting.

NOTE: If the can bursts, it is important to safely dispose of it in a manner where no one, including animals, will be able to access it as it can be quite harmful if consumed.

Tip #2: Store Cans According to Expiry Date

You may purchase new canned goods without consuming the canned food you already have in your cupboard.

A great way to prevent having expired cans of food is to pack your cupboard shelves so that the oldest cans are in front and the new cans are behind them. This way, the oldest can be used up first, and the newer cans will be stored for later.

This storage approach is a great solution if you like to buy canned goods so you don’t end up with a bunch of expired cans. 

Tip #3: Freeze Raw Canned Biscuits

It is advisable to freeze and store the biscuits separately. Here are the steps:

• open the can
• separate the raw biscuits
• lay them out on a baking sheet
• freeze

When freezing your canned biscuits on the baking sheet, ensure that the biscuits do not touch each other so they don’t stick together.

Once the biscuits are frozen, transfer them to an air-tight freezer bag (I like these reusable ones on Amazon) and store them in the freezer. 

Tip #4: Defrosting Frozen Canned Biscuit Dough

It is important to thaw frozen biscuit dough in the refrigerator to keep them chilled while they return to its original state. Avoid thawing canned biscuits on the countertop, as the drastic change in temperature negatively impacts the dough.

Unfortunately, it is possible that you may find that the thawed dough is sticky and does not have the same quality texture as the dough would fresh out of a can. 

Potential outcomes when eating foods that have gone bad

Here are a few potential outcomes that may occur when eating foods that have gone bad.

1. Stomach Bug: Eating foods that have gone bad can potentially lead to you experiencing an upset stomach as the mold or bacteria in the food does not agree with your body, and your body is trying to get rid of it urgently. 
2. Nausea and Vomiting: Apart from experiencing an upset stomach, it is also possible that consuming foods that have gone bad may result in nausea and vomiting. Check the expiry date and inspect the biscuits once prepared to ensure that there are no signs of spoilage, as these are indicators that your biscuits have gone bad. 
3. Perfect Health: It is entirely possible that you can eat something that has gone bad without having any adverse side effects. Everyone’s body is different. One person’s tolerance to a meal may be entirely different from another’s.

Conclusion

Canned biscuits can generally be consumed within a week after they have been baked. However, if the biscuits were not stored suitably, they could go bad in less than a week. Signs of spoilage include:

• mold
• strange smells
• odd colors

If you detect any signs of spoilage, the biscuits should not be eaten.

The storage time indicated on the can reflects the date until which the canned biscuits will remain top quality. If the expiry date has passed, the biscuit may change:

• flavor
• color
• texture

Nonetheless, canned biscuits are likely to be safe to consume if, stored properly, and the package is undamaged with no signs of spoilage.

Miso soup is a great tasting and very healthy food. It contains miso paste, which is known for lasting a very long time without going bad, and because of this you may be wondering, does miso soup go bad? Or can it also last up to a year in the right conditions?

Miso soup does go bad. If the soup is kept in the fridge, it can last for 2 to 3 days before it goes bad, but it can go bad if kept for longer. So, do not treat miso soup the same way that you would treat miso paste (which may last up to a year when kept in the fridge), assuming it will last long. 

What exactly goes into miso soup that can cause it to go off when miso paste on its own can last so long then? What makes this soup have such a short timeframe for when it is suitable to eat it? Let’s take a closer look.

Does Miso Soup Go Bad?

Miso soup can go bad, and it could happen in a relatively short period of time. The reason so many people often think that miso soup won’t go bad is because of the longevity of the miso paste itself.

Miso paste is a fermented product, and it also contains a lot of salt, making it a very well-preserved product that can last up to a year in the refrigerator. Miso paste hardly ever goes off, making it an easy product to store for long periods of time. If you’re interested in making your own miso soup, I like this miso from Amazon.

However, this does not mean that miso soup will be the same. Remember that miso soup is still a fresh product that contains other ingredients in it that can still go off quickly.

The fresh ingredients that are used in miso soup can vary, but alongside miso paste, often other products that are used in miso soup include seaweed, tofu, and fresh vegetables.

Due to the fact that this soup also contains miso paste, a product that is so high in probiotics, it actually leaves the soup at a greater risk of going bad quicker due to the live bacteria in the prepared soup.

How Long Until Miso Soup Goes Bad?

Miso soup will generally only last for a few days after it has been made before it will go bad. How quickly it goes off will also depend on how you store the soup.

Once you have finished eating your miso soup and you are ready to pack the left-over soup away, you should start by allowing the soup to cool down entirely. This can sometimes take hours, but have patience because it is important.

Once the soup is completely cooled down, you will need to put it in an airtight container and store it in the fridge.

Miso soup that is stored in the fridge will usually last two to three days before going bad – this is a relatively short amount of time to be able to store something in the fridge before it goes off, but as was discussed, miso soup has live bacteria in it.

DID YOU KNOW? The live bacteria in miso soup is incredibly good for you and for your gut health as it is so rich in probiotics. This soup also contains many other minerals and vitamins that your body needs, such as vitamin K, vitamin E, and folic acid, to name a few.

Fresh food products that do not have preservatives in them do unfortunately go bad quicker than foods that are not fresh and that are full of preservatives.

So, even though it may feel frustrating that your miso soup would go bad so quickly, just remember that it is actually a good thing, as it indicates that the miso soup is a fresh and high-quality food – and sometimes the price you pay for fresh and high-quality food is that you will not be able to keep it as long.

How Do You Know if Miso Soup Has Gone Bad?

There are a few different key ways that you will know whether or not your miso soup has gone bad or if it is still fine to eat. However, if you are ever unsure of whether or not it has gone bad, it’s best not to eat it.

Eating miso soup that has gone bad can give you food poisoning, or at the very least, cause some intestinal distress. So when it comes to old miso soup, if you are unsure it’s best to play it safe rather than be sorry that you ate it.

Some of the signs to look out for when it comes to telling if your miso soup has gone bad include:

• A bad smell – miso soup has a very unique smell, but if this smell ever changes and develops a pungent or sour smell, throw it away as there is a high chance it has gone bad.
• Mold – this should be a fairly obvious one; however, if there is ever any mold that has started to grow on your miso soup it is a good indication that the soup has gone bad. Do not try and scrape the mold off and eat the soup, just throw the soup away.
• If it’s older than a week – with miso soup only lasting about 2 to 3 days in the fridge before going off, if you have some left-over miso soup in your fridge from last week do not eat it. There is a very high chance that it will no longer be suitable for consumption.

If there are ever other abnormalities in your leftover miso soup, such as discoloration or anything else, it’s better to discard the soup than take the risk.

How Long Does Miso Soup Last Out of The Fridge?

Leaving miso soup out of the fridge is a risky thing to do. Miso soup only lasts two to three days in the fridge, so without being kept in a cool environment to help it keep fresh for as long as possible, chances are that your soup will not stay edible for very long.

The exception to this, however, is the possibility of leaving your soup out on the stove overnight.

If you are wanting to cook your soup a day in advance for whatever reason, you can do the following:

• Prepare and make your miso soup just as you normally would.
• Once the soup is finished, put the lid on your pot, and turn the stove off.
• Leave your soup in the pot with the lid on overnight (once the oven plate has completely cooled down, you can even wrap a kitchen tea towel around the pot and put one over the lid to keep as much warmth in as possible.)
• When you wake up the next morning, warm the soup up again on medium heat for around 10 minutes to make sure it has warmed up all the way through, and you can then serve your soup when ready.

This is not a fail-proof way to always ensure that your soup will last well being left out overnight, so always use discretion before eating the soup to ensure that it did not go bad overnight. 

Conclusion

Miso soup can definitely go bad, and it can actually happen in a very short time frame. It’s always important to exercise caution and check that your left-over miso soup is still okay to eat before you dive right in come lunchtime.

If you are ever unsure as to whether your soup is still fine to eat, first look for the obvious signs of the soup being off, but if you have done the checks and you are still just completely unsure if it is fine – give it a pass.

Old miso soup that has gone bad can give you food poisoning as well as just a bad case of intestinal distress if consumed, so always play it safe when it comes to eating miso soup after a few days. If it is not clear that it is still fine to eat, just skip it.

If you have ever fermented something at home, whether it be a sourdough starter, beer, kombucha, or something else entirely, you have probably found yourself asking: do light and heat help fermentation? What is the ideal environment for fermentation?

Light does not help fermentation, but heat does. While fermentation requires a dark environment to truly thrive, having a warm environment for the fermentation to take place in will really help the process – it should not be too hot or too cold, just warm. 

Heat will help the fermentation process, but light will not. Let’s take a closer look at exactly why heat and darkness can aid in fermentation but light does not, and how to create the perfect environment for fermentation.

Does Sunlight Help Fermentation?

Sunlight does not help the fermentation process. While fermentation requires a dark environment to truly thrive, warmth will also really help the process. It should be neither too hot nor too cold.

The bacteria that do all the work when it comes to the fermentation process are called lactic acid-producing bacteria, otherwise known as LAB.

The lactic acid-producing bacteria are very negatively affected by sunlight. The UV rays from the sunlight more often than not will end up killing the lactic acid-producing bacteria.

Due to sunlight being so harmful to the lactic acid-producing bacteria, and therefore being harmful to the fermentation process as a whole, it is generally advised that when fermenting anything, it should be kept in a dark room or a shady area. 

TIP: If you are unable to store whatever it is that you are fermenting in a dark area, at least make sure it is an area that will always be out of direct sunlight.

If you live in a city where you do not get much natural sunlight in certain seasons, it would be fine to leave whatever item that you are fermenting on your kitchen counter as long as you know for a fact that your fermenting item will remain out of direct sunlight.

Does Heat Help Fermentation?

Fermentation actually requires a certain level of heat for the process to take place efficiently. The heat will help in the fermentation process up to a certain point – and after that, it may become harmful.

Fermentation processes thrive in a warm environment. For example, if you are fermenting a sourdough starter, wrapping a cloth around your jar may help the fermentation process go quicker than it normally would have without the extra warmth. 

NOTE: The ideal temperature for a room at for fermentation would depend on what it is that you are fermenting, as different fermentation processes require different heats.

If you are fermenting homebrew (beer, for example), the room should be somewhere between 90ËšF to 95ËšF (which is 32ËšC to 35ËšC).

However, if you are fermenting vegetables, the ideal temperature of the room you are fermenting the vegetables in would be around 70ºF (which is 21 ËšC ). The room shouldn’t be warmer than 72ºF (22 ËšC) or cooler than 68ºF (20 ËšC)

When the room is too warm, the yeast in the fermentation process may become overly active. If the room is too hot, the yeast could die, making the fermentation process completely inactive. This room thermometer from Amazon can help you be sure of the specific temperature where you are storing the ferment.

This means that you will see little to no results, as the yeast will not be working hard enough for any fermentation to take place.

Not only does heat help fermentation, but without enough heat, fermentation may not take place at all. If it does, it may be in such a small amount that you won’t even be able to tell that it is fermenting.

What is the Ideal Environment for Fermentation?

Fermentation is not necessarily complicated; however, it does require a few specific conditions in order for the process to take place as well as it possibly can.

The environment in which the fermentation process takes place is probably the biggest factor in what the results of the fermentation will be – because of this, it is very important to make sure you have the ideal environment ready and available for use.

As discussed above, the fermentation process does not do well in light, which means that the first aspect that is important in the ideal fermentation environment would be darkness.

Having a dark environment helps the lactic acid-producing bacteria thrive, meaning that your fermentation process will thrive too.

The second aspect that is crucial when it comes to fermentation is the temperature of the room. As we discussed above, the ideal temperature of the room will vary depending on what it is that you are fermenting.

TIP: Finding out the ideal temperature for the item you are fermenting should be the first step that you take, and once you have figured that out, you will need to try to find a space in your house that is as close to that temperature as possible.

To sum it up: the ideal environment for fermentation is a dark place with the right temperature. It is not complicated; it may just be a bit of a tricky process trying to find the space with these conditions!

What Can I Do to Speed Up Fermentation?

Fermentation is mostly a waiting game. It is not something that can be quickened or rushed or forced to go faster than it can.

The bacteria needs time to work, and the yeast also needs time to feed in order to produce all of its sought after goodness – it cannot happen overnight.

However, if you need the fermentation done quicker than usual for whatever reason, here are a few things that you could try to speed up fermentation:

• If the fermentation recipe requires you to add yeast, you can add slightly more yeast than is required – the more yeast that is at work, the quicker the fermentation will go.

• Turning up the heat ever so slightly (for example, wrapping a blanket around the jar) could help assist the yeast in being more active – they will feed on the sugars and starches faster, though, so be sure there is enough food for them.

• Add less salt if you are fermenting vegetables – the salt will slow down the fermentation process, so by adding less salt, it will go faster by default.

NOTE: There are not many things at all that will speed up the fermentation process or give you overnight results, so the best thing you can do is have patience.

Conclusion

Fermentation can be a delicate process since you are dealing with bacteria, and knowing what helps the process and what does not help can make or break the end result.

While light does not help with fermentation, heat does, so use this knowledge wisely.

Keep the jar of whatever is it that you are fermenting in a dark and warm environment, as it will help the process thrive and will give you the best chance of getting the results that you are after in the final product.

And at the end of the day, fermentation needs time, time, and more time. It is a relatively long process, but it is well worth it in the end.

As much as you may want to set up your fermentation one day and wake up the next day to a finished product, this is unfortunately not the way this process works. So set up your fermentation process, then sit back and relax, because the end results will be worth your time!

Fermenting vegetables is a practice that has been done for thousands of years. In modern times, even with all the tools of the trade and experience with fermenting veggies, you can still end up with a soggy and mushy mess of a fermented vegetable, and no one likes a soggy veggie. So, how do you keep fermented veggies crisp?

There are many ways to keep fermented vegetables crisp; let’s dive in and go into more detail about each step and how it will aid you in making perfectly crisp fermented veggies. Here are the basic steps to learn about when it comes to keeping your fermented veggies crisp:

1. Use fresh, firm veggies
2. Use sea salt for brine
3. Add tannins to the brine
4. Remove blossom ends of veggies
5. Soak veggies in ice water
6. Pierce skin of thick veggies
7. Ferment at cool temperatures
8. If it’s hot, ferment for less time
9. Taste the veggies often

Steps To Keep Fermented Veggies Crisp

Keeping your fermented veggies crisp can be a challenge as one day can mean the difference between a crisp fermented veggie and a soggy, mushy veggie that no one wants to eat.

Thankfully, there are some things we can add to the brine before we put the veggies in it, and a few things we can do to prepare the veggies before they go into the brine to help them stay crisp, crunchy, and good to eat.

We also need to ensure that we have full control over how fast our veggies ferment to help us get the crisp fermented veggies that we like.

Fermenting the vegetables too quickly can have undesirable results and turn your veggies into mush inside the jar. Here is what we can do to the brine and the veggies to ensure a better crisp that lasts longer.

#1: Use Fresh and Firm Veggies

To help ensure that you get the crispness you enjoy from your fermented vegetables, you should start with quality vegetables. The fresher the vegetables are, the better the ferment will turn out to be.

TIP: The ideal situation is to use fresh-grown garden vegetables that are harvested on the same day that you intend to ferment them. You can’t get vegetables any fresher than that!

Make sure that your vegetables do not have any soft spots and that they do not look too wrinkly. If any are bruised during the harvesting process, it’s best to use that particular vegetable in a meal rather than include it in the ferment.

Bruised vegetables tend to get mushy much quicker than unbruised vegetables, so take your time to select the best ones.

You want to use the best and most fresh veggies that you can get your hands on. Whether you have the opportunity to pick vegetables fresh from the garden or get some from a local farmer’s market, then those veggies would be the ideal candidates to use for fermenting.

REMEMBER: If your veggies have any soft spots, or bruises, or are on the slightly over-ripe soft side, then it is best not to use them for fermenting. If you want your fermented veggies to be crisp, these old veggies that are past their prime will go even softer during the fermentation process.

Essentially, the reason that they will go soft is that they have already started to decompose. The decomposing process creates additional sugars that become part of the ferment and can result in unintended textures and tastes for your ferment.

This could also add different bacteria into the fermentation, which can cause the ferment to react differently and affect the final outcome of the vegetables.

#2: Use Sea Salt When Making Brine

Once you have fresh veggies, you can begin to make the brine for fermentation which is a crucial ingredient that is imperative to get right. The salt in the brine helps to control and prevent harmful bacteria from growing and multiplying in the fermentation.

The salt also helps to create a positive saline content around the vegetables, which draws excess water out of the vegetables and helps to keep them crisp and firm.

NOTE: The best and healthiest choice for the salt component is to use natural sea salt. The reason why sea salt is the best to use for fermentation is that sea salt contains minerals like magnesium and calcium. This sea salt from Amazon works great.

To make the best brine for crispy fermented veggies, it is best to have about a 4-5% salt concentration as this will help bring out the crispiness of the veggies.

To make a brine solution that has the right salt concentration for your ferment, use one of these ratios:

• For a 4% salt concentration, use two tablespoons of sea salt per 4 cups of pure water.
• For a 5% salt concentration, use two and a half (2.5) tablespoons of salt per 4 cups of water.

TIP: Try both salt concentrations to know which you like best, everybody’s tastes are different. Some people like the 5% but for others, it may be too salty.

A note on water:

Ordinary tap water is not the best medium for making brine. Most tap water contains fluoride and chlorine, which are both chemicals that are designed to reduce the quantities of microorganisms in the water.

These chemicals in tap water will hinder your ferment and could produce unsatisfactory results, such as slowing the ferment or reducing the effectiveness of the ferment.

It’s best to use filtered water or distilled water where the concentration of these chemicals has been reduced or eliminated completely. This water filter from Amazon is very good quality and perfect for filtering water for drinking and fermenting.

#3: Add Tannins to the Brine

Adding tannins to the brine is one of the best ways to keep your veggies from going soggy while fermenting. Once the brine is made and completely ready, add tannins before you add in your veggies.

Tannins will help prevent the cell walls of your veggies from breaking down, which is one of the causes of veggies going soggy. Tannins are the best thing to add to your brine to keep your fermented veggies crisp. We will go through tannins and tannin sources later on in this article.

#4: Remove the Blossom Ends of Veggies

The ends of the vegetables that connected them to their plants are known as the blossom end. This end of the veggies needs to be removed before they are soaked because it contains an enzyme that will soften and break down your veggies.

This is a natural reaction in the plants that causes the vegetable to continue to ripen, which encourages it to soften. However, this is the outcome we are trying to avoid and we do not want this to happen during fermentation.

So, use a knife to cut off a very thin slice from the blossom end of your veggies; this will help the veggies to keep their firm texture throughout the fermentation process. If you do not do this, then there is a chance that your veggies may go soggy while fermenting.

#5: Soak the Veggies in Ice Water Before Fermenting

Once the veggies have been trimmed and the brine has been made, soak the vegetables in ice water for about one to two hours before you place them in the brine.

Soaking vegetables in ice water will help them get nice and firm. This process cools down the water in the cells of the vegetables and also allows them to absorb any water that they are lacking.

REMEMBER: Vegetables can be a bit dehydrated without looking wilted, but you want them nice and hydrated for fermenting so they can stay crisp. Soaking them is a helpful task for hydration!

#6: Puncture the Skin of Thick Veggies

Some vegetables have harder skin compared to others, so for these hard-skinned veggies, you should pierce the skin a few times around the vegetable before you place them in the brine.

Use a paring knife or a skewer to puncture the skin of the vegetable. The vegetables can get a bit slippery during this process, so be sure to have a firm grip on the vegetable and the tool you are using to puncture it with.

Piercing vegetables that have hard skin helps the brine to penetrate into the vegetable faster, allowing it to culture more evenly. Faster brine penetration and faster culture time will help your veggies to stay crisp as it will take less time for them to ferment.

Once this is done, then it is finally time to place the veggies into the brine and get the fermentation process started!

#7: Ferment at a Colder Temperature

Once the veggies are in the brine and you have sealed the container properly, place the container in a cool place in your house. If your house is too warm, it can cause problems with the fermentation process. A hot fermentation can speed up the process too much and lead to your veggies losing their crispiness.

To keep your fermenting veggies cool throughout fermentation, you can place them in a cool and dark kitchen cabinet that does not get direct sunlight at any point in the day, or you can place your fermenting veggies in the fridge to keep them cool.

NOTE: Cooler temperatures do make the fermentation process take a bit longer, but give you more control over the process, and will keep your veggies at the crispiness you prefer.

#8: If It’s Hot, Ferment the Veggies For Less Time

If you do not have a cool place to keep your fermenting veggies, you can still ferment your veggies in a warmer environment and yet keep the veggies crisp. This will be a bit more difficult and require a bit more work as you will need to monitor your fermentation much more closely.

If the temperature in your house is over 75 degrees Fahrenheit (23 degrees Celsius), then you should ferment your veggie for a shorter amount of time.

In these conditions, you should check your fermenting veggies after about three days to see if they are ready yet or not. If they are not ready, then leave them for another two days and then check them again.  

Hot temperatures will make your veggies ferment quicker, which could make them lose their crispiness and turn soggy if you do not watch them and stop the fermentation when it needs to be stopped.

#9: Taste the Veggies Frequently

Once the veggies have been fermenting for a bit, open them up and cut a small piece of the vegetable, and taste it. This will help you know if your fermented veggies are ready or not.

Check your ferment on a regular basis. Fermenting can be a finicky process and it can only take one day without checking your vegetables for them to change and go soggy.

TIP: If your fermented veggies start to show signs of going soggy, you need to place them in the fridge immediately to stop the sogginess from going any further.

Natural Sources of Tannin for Fermentation

Tannin is a great help to people who want to make crisp and delicious fermented vegetables. Tannin is one of the best things you can add to your fermenting veggies to keep them crisp. Almost all fermenters will highly recommend putting tannin in your brine when fermenting veggies.

If you do just one of the steps mentioned above to keep your veggies crisp, add tannin to your ferments. This is one of the best and simplest ways of keeping fermenting veggies crisp; it may even be called a trade secret for fermenters.

DID YOU KNOW? Most people who ferment veggies will use grape leaves when fermenting to add tannin to their ferments. Grape leaves have some of the highest concentrations of tannin in them that you can get.

However, it can sometimes be hard to get a hold of some grape leaves, thankfully, and to the delight of fermenters everywhere, there are many sources of tannin that you can use apart from grape leaves, and they are quite easy to acquire.

Good Sources for Tannin to Use in Fermenting

• Bay leaves (these ones from Amazon are great)
• Cherry leaves
• Black currant leaves
• Indian almond leaves
• Raspberry leaves
• Horseradish root, chopped or grated (order it here from Amazon)
• Horseradish leaves
• Sour cherry leaves
• Mesquite leaves
• Oak leaves (these contain the highest amount of tannins, so be careful, you only need a little)
• Green banana leaf
• Loose tea leaves
• A tea bag

These are all great sources of tannin, but bay leaves are by far the easiest one from the list to get your hands on. Only need about two to four bay leaves per quart when fermenting to achieve the best crisp for your veggies.

Conclusion

There are methods we can use to help our fermented veggies to stay crisp while fermenting: changing the type of salt used and the salt concentration in the brine, fermenting in a cool environment, adding some tannin, and more. All of these methods help the structure of the vegetables and keep them firm.

These fixes for soggy fermented veggies are easy to implement and will allow you to control the amount of crisp you want your veggies to be. Follow them and enjoy your crisp fermented veggies!
