If you are a fan of sauerkraut, you probably know that this tangy cabbage dish can last for a long time. But what about opened sauerkraut? How long can you keep it in the refrigerator before it goes bad?
The good news is that opened sauerkraut can last for several weeks in the refrigerator, as long as it is stored properly. The key to keeping sauerkraut fresh is to keep it submerged in its own brine. This brine acts as a natural preservative, preventing the growth of harmful bacteria.
When storing opened sauerkraut, it is important to use an airtight container to prevent any air from getting in. This will help maintain the quality and flavor of the sauerkraut for a longer period of time. Additionally, make sure to keep the sauerkraut refrigerated at a temperature below 40°F (4°C) to slow down the fermentation process.
The Shelf Life of Opened Sauerkraut in the Refrigerator
Sauerkraut is a popular fermented cabbage dish that is known for its tangy and sour flavor. Many people enjoy sauerkraut as a topping for hot dogs or as a side dish. If you have opened a jar of sauerkraut and are wondering how long it will last in the refrigerator, it is important to know that it can stay fresh for a certain period of time.
Once you have opened a jar of sauerkraut, it is recommended to store it in the refrigerator to maintain its freshness. The cold temperature slows down the fermentation process and helps to preserve the sauerkraut for a longer period. It is important to keep the sauerkraut covered in its original brine to prevent it from drying out and to maintain its flavor.
The shelf life of opened sauerkraut in the refrigerator can vary depending on various factors. On average, opened sauerkraut can last for about 1-2 months when stored properly in the refrigerator. However, it is essential to check for any signs of spoilage before consuming it.
Some common signs of spoilage in sauerkraut include a foul smell, mold growth, or a slimy texture. If you notice any of these signs, it is best to discard the sauerkraut to avoid the risk of foodborne illnesses.
To extend the shelf life of opened sauerkraut, you can transfer it to an airtight container or a resealable bag. This will help to prevent any air from reaching the sauerkraut and slow down the spoilage process. Always make sure to label the container with the date you opened the sauerkraut to keep track of its freshness.
In conclusion, opened sauerkraut can last for 1-2 months in the refrigerator when stored properly. It is important to be mindful of any signs of spoilage and discard the sauerkraut if necessary. Enjoy your sauerkraut as a delicious and tangy addition to your meals!
Factors Affecting the Storage Time of Opened Sauerkraut
Proper storage is essential for ensuring the longevity and safety of opened sauerkraut. The storage time can be influenced by various factors, including:
1. Temperature
Temperature plays a crucial role in determining how long opened sauerkraut can be stored in the refrigerator. It is recommended to keep the sauerkraut at a temperature below 40°F (4°C). Lower temperatures help slow down the growth of bacteria and extend the shelf life of the sauerkraut.
2. Packaging
The type of packaging used to store opened sauerkraut can affect its storage time. It is best to transfer the sauerkraut to an airtight container or resealable bag after opening the original packaging. This helps prevent air exposure and maintains the quality of the sauerkraut for a longer period.
Note: If the original packaging is resealable and airtight, it can be used to store the sauerkraut.
3. Contamination
Contamination can significantly reduce the storage time of opened sauerkraut. It is important to use clean utensils and hands when handling the sauerkraut to avoid introducing any harmful bacteria. Any signs of mold, off-putting odor, or sliminess indicate spoilage, and the sauerkraut should be discarded immediately.
4. Air Exposure
Avoiding air exposure is crucial in preserving the quality and storage time of opened sauerkraut. Exposure to air can promote the growth of bacteria, leading to spoilage. Always ensure the container is tightly sealed to prevent air from entering.
By following these factors and storing opened sauerkraut correctly, it can last for approximately 1-2 weeks in the refrigerator without compromising its safety and taste.
Tips for Properly Storing Opened Sauerkraut in the Refrigerator
Once you’ve opened a jar of sauerkraut, it’s essential to store it correctly in the refrigerator to maintain its freshness and quality for as long as possible. Here are some tips to help you properly store opened sauerkraut:
1. Transfer the sauerkraut
After opening the jar, it’s recommended to transfer the sauerkraut to an airtight container. A glass or plastic container with a tight-fitting lid works best. This step helps to preserve the sauerkraut’s flavor and prevent it from absorbing other odors in the fridge.
2. Seal the container tightly
Make sure to seal the container tightly to prevent air from entering. Exposure to air can lead to the growth of mold or bacteria, which can spoil the sauerkraut. It’s advisable to press down on the sauerkraut to remove any excess air before sealing the container.
3. Store in the refrigerator
Place the sealed container of sauerkraut in the refrigerator as soon as possible. The cool temperature of the fridge helps slow down the fermentation process and maintain the sauerkraut’s texture and taste. Ideally, the sauerkraut should be stored at a temperature of around 36-40°F (2-4°C).
4. Keep away from light
Sauerkraut is best stored in a dark place in the refrigerator. Exposure to light can cause the sauerkraut to become discolored and develop off flavors. For this reason, it’s recommended to store sauerkraut in the back of the fridge or in a drawer.
5. Check for signs of spoilage
Regularly check the sauerkraut for any signs of spoilage, such as an off smell, slimy texture, or unusual discoloration. If you notice any of these signs, it’s best to discard the sauerkraut to avoid the risk of foodborne illness.
By following these tips, you can prolong the shelf life of opened sauerkraut and enjoy its tangy flavor in various recipes for an extended period.
Signs of Spoiled Sauerkraut to Look Out For
While sauerkraut can last for a long time in the refrigerator when stored properly, there are certain signs you should be aware of to determine if it has gone bad. Here are some common signs of spoiled sauerkraut:
1. Foul Odor
One of the first indicators that your sauerkraut has gone bad is a foul or off-putting odor. If it smells rotten, sour, or otherwise unpleasant, it’s likely that the sauerkraut has spoiled and should be discarded.
2. Mold Growth
Another visible sign of spoiled sauerkraut is the presence of mold growth. If you notice any green, black, or white spots on the surface of the sauerkraut or inside the jar, it is a clear indication that the fermentation process has gone awry and it’s no longer safe to consume.
Remember: Even a small amount of mold can indicate the presence of harmful toxins, so it’s important to play it safe and avoid consuming moldy sauerkraut.
3. Unpleasant Texture
Spoiled sauerkraut may have a slimy or mushy texture, which is another sign of spoilage. When sauerkraut goes bad, the texture changes from crisp and crunchy to soft and unpleasant.
4. Discoloration
If your sauerkraut has undergone a noticeable change in color, it’s likely that it has started to spoil. Look out for sauerkraut that has turned brown, darkened significantly, or has any other unnatural coloration.
5. Gas Formation
When sauerkraut ferments, it produces carbon dioxide, which leads to the buildup of gas. However, if your sauerkraut exhibits an excessive amount of gas formation, with the jar lid bulging or popping, it can be a sign of spoilage.
Note: When in doubt, trust your senses. If something seems off about the sauerkraut, it’s better to err on the side of caution and throw it away.

Alternative Storage Methods for Sauerkraut
If you have opened a jar of sauerkraut and need to store it for an extended period, there are alternative methods available besides keeping it in the refrigerator. While refrigeration is the most common and recommended method, these alternatives can be helpful in certain situations.
1. Canning: Canning is a popular method for preserving sauerkraut long-term. When properly canned, sauerkraut can last for up to a year without refrigeration. The process involves sterilizing jars, filling them with sauerkraut, and sealing them tightly. The jars are then submerged in boiling water to create a vacuum seal, ensuring the safety and longevity of the sauerkraut.
2. Freezing: Freezing sauerkraut is another option for long-term storage. After opening the jar, transfer the sauerkraut into an airtight container or freezer bags. Make sure to remove any excess brine before freezing. Sauerkraut can be stored in the freezer for up to six months without losing its flavor and texture. Thaw the sauerkraut in the refrigerator before using it.
3. Fermentation Crocks: Fermentation crocks are specially designed containers used for fermenting and storing sauerkraut. These crocks have a water-sealed lid that allows gases to escape during the fermentation process while preventing air from entering. While this method requires an initial fermentation period, the sauerkraut can be stored in the crock at room temperature for several months.
4. Vacuum Sealing: Vacuum sealing is an effective method for preserving sauerkraut without refrigeration. It involves using a vacuum sealer to remove all the air from the packaging, creating an airtight environment. This method helps to maintain the quality and freshness of the sauerkraut for an extended period.
Although these alternative storage methods can be useful, it’s important to note that refrigeration is still the best option for maintaining the quality and taste of sauerkraut. When using alternative methods, monitor the sauerkraut carefully for any signs of spoilage, such as a foul odor or mold growth. Discard the sauerkraut if any of these signs are present to prevent foodborne illness.
