How Long Does Sauerkraut Last in the Fridge?
How to Store Sauerkraut and Identify Spoilage
Sauerkraut lasts about 1–3 months in the refrigerator when kept in an airtight container.
Sauerkraut is a fermented staple known for its tangy flavor and probiotic benefits. Because it undergoes lactic acid fermentation, it is naturally more shelf-stable than fresh cabbage; however, maintaining its quality requires proper handling once opened. Storing sauerkraut in the refrigerator slows down the fermentation process, which helps preserve the characteristic crunch of the cabbage. To prevent the vegetable from absorbing unpleasant fridge odors or losing its acidity through oxidation, always keep it tightly sealed. While it remains safe to consume for several months if handled correctly, monitoring texture and aroma is essential to ensure you are eating it at peak freshness.
Heads up: shelf-life ranges are estimates based on home storage. We make no guarantee of accuracy. When unsure, throw it out.

Common questions
How long does sauerkraut last in the refrigerator?
Sauerkraut typically stays fresh for 1–3 months in the refrigerator when stored in an airtight container.
Can I freeze sauerkraut to extend its shelf life?
You can freeze sauerkraut, but be aware that freezing breaks down the cabbage's cell walls, resulting in a very soft texture once thawed.
How should I store opened sauerkraut?
Always keep opened sauerkraut in an airtight container inside the refrigerator to prevent oxidation and odor absorption.
Is it safe to eat limp sauerkraut?
If the cabbage is soft but lacks mold, slime, or a foul odor, it is generally safe. It is best used in cooked recipes like stews rather than eaten raw.
Keep your kraut in a tight jar and enjoy that tangy crunch for months!
