How long does sauerkraut last?
Properly fermented and stored sauerkraut has an impressively long shelf life. It can easily last for 4–6 months when kept refrigerated in an airtight container or jar. The lactic acid produced during fermentation acts as a natural preservative, preventing the growth of harmful bacteria. With ideal storage conditions, some sauerkraut enthusiasts claim their homemade batches can last for up to a year.
