Expiration & Storage Tips
When does sauerkraut expire?
Unopened jars of commercial sauerkraut can last up to 18 months in the pantry, even beyond their printed best-before date provided they're stored in cool, dry conditions. However, once opened, the product should be stored in the fridge and consumed within two weeks for optimal flavor and safety. Homemade sauerkraut, which doesn't contain preservatives used in commercial production, typically lasts up to a year if canned properly and stored in a cool, dry place. Once opened, it's best to consume it within a month. If you choose to freeze your sauerkraut, it can extend its life for up to a year. But remember, freezing might alter its texture a bit. To defrost, simply transfer it to the fridge a day before you plan to consume it.
How do you tell if sauerkraut is bad?
Spoilage in sauerkraut is easy to spot but sometimes can be tricky. Look for changes in color, noticeable mold, or an off smell. A good sauerkraut should have a pale to medium yellow color, should be submerged in brine, and have a tangy smell. If it's unusually dark, has a slimy texture or an off smell, discard it immediately. Always avoid tasting it if you suspect it’s spoiled as it can cause foodborne illness.
Tips for storing sauerkraut to extend shelf life
• Store unopened jars of sauerkraut in a cool, dry and dark place, away from heat sources.
• Once opened, always keep your sauerkraut refrigerated and make sure it’s submerged in its brine, which acts as a natural preservative.
• Homemade sauerkraut should be stored in airtight jars. When consuming, always use clean utensils to prevent contamination.
• If you've made a large batch, you can freeze a portion of your sauerkraut in airtight freezer-safe containers.
• Opened sauerkraut can be transferred to a resealable plastic bag before being stored in the refrigerator to help prolong its shelf life.
