Sauerkraut is fermented cabbage and is a popular food item in Northern European countries. It can be eaten as a side dish or as a topping on sandwiches and burgers. You may wonder if sauerkraut goes bad like other vegetables.
Does Sauerkraut Go Bad?
Sauerkraut is a fermented vegetable condiment, but it can start to spoil if it is not stored correctly.
Sauerkrauts that are dried out can go bad in as soon as a few days. For that reason, they should always be kept airtight to prevent moisture from escaping.
On the other hand, the sauerkraut can go bad if they become too moist. This will allow the bacteria to start to contaminate it.
This happens when the bacteria levels rise too high and the air can’t reach all the kraut in the jar. The bacteria will release an acidic gas which becomes toxic and starts to produce other smells.
There are different types of bacteria that live on cabbage and they will produce different smells depending on what type of bacteria is present. For example, Lactobacillus produces butyric acid, acetoin, and hydrogen sulfide whereas Pediococcus produces ethyl mercaptan and propionic acid.

How to Store Sauerkraut
Sauerkraut is a fermented food that can be stored for a long time without refrigeration. There are some factors that you need to consider while storing sauerkraut.
Sauerkraut is a type of cabbage that is fermented by lactic acid bacteria. The fermentation process takes about 2-4 weeks to complete, depending on how sour the cabbage is. Sauerkraut is usually served at room temperature or slightly chilled, though it can also be served hot or cold.
The best way to store sauerkraut is in an airtight container in the refrigerator for up to 8 weeks.
If you need to store them longer than 8 weeks, you can freeze them for up to 6 months.
Whether the sauerkraut is stored in the fridge or freezer, it should always be kept in an airtight container or freezer bag at all times.
How to Keep Sauerkraut Fresh Longer
Sauerkraut is a fermented cabbage dish that has been a part of traditional German and Scandinavian food since the Middle Ages.
It’s important to note that sauerkraut can be kept fresh for up to 3-4 weeks with proper storage. This is because the fermentation process eliminates most of the water from the cabbage, leaving behind more concentrated flavor and nutrients.
Here are some tips for how to keep your sauerkraut fresh longer:
- Keep your kraut refrigerated. This will make it last longer and maintain its original quality and flavor. The cooler temperature also slows down the fermentation process and keeps harmful bacteria at bay.
- Keep the sealed in an airtight container or plastic bag.
- Take out all the air from within the jar and replace it again with an equal amount of brine solution.
- Turn your bowl or jar upside down in order for the brine solution to drain out and replace it with clean water.
- If you are using a smaller container, use only one big spoonful of brine at a time and make sure you don’t let.
Does your kraut taste sour?
If the krauts aren’t sour and also don’t have a strong and persistent odor of fermentation, then it’s likely safe for consumption.
