How long does sauerkraut last in the refrigerator? Tips & Tricks!

Sauerkraut is a fermented food that has become popular in recent years. It’s not only delicious but also nutritious. Sauerkraut contains vitamins, minerals, and probiotics, which promote gut health. But how long can you keep sauerkraut in the refrigerator? Here are some tips and tricks to help you store sauerkraut properly and make it last longer.

What is Sauerkraut?

Sauerkraut is a German word for sour cabbage. This food is made from finely shredded cabbage that is fermented by lactic acid bacteria. The fermentation process takes several days to several weeks, depending on the temperature and the amount of salt used. The result is a tangy, crunchy, and slightly sour food that can be enjoyed as a side dish or used in sandwiches, salads, and other recipes.

How Long Can Sauerkraut Last in the Refrigerator?

Sauerkraut can last for several months in the refrigerator if stored properly. The key to keeping sauerkraut fresh is to prevent air from entering the jar or container, which can cause oxidation and spoilage. Here are some tips to help you store sauerkraut:

Use an Airtight Container

When you buy sauerkraut or make your own, transfer it to an airtight container for storage. A glass jar with a lid or a plastic container with a tight-fitting lid is ideal. Make sure the container is clean and dry before adding the sauerkraut.

Keep It Refrigerated

Sauerkraut should be kept in the refrigerator at a temperature between 32°F and 40°F. The cooler the temperature, the longer it will last. If you have a root cellar or a cool basement, you can store sauerkraut there if the temperature is right. However, make sure the container is airtight to prevent any insects or rodents from getting in.

Store It on the Bottom Shelf

The bottom shelf of the refrigerator is the coldest and most stable, making it the best place to store sauerkraut. Avoid storing sauerkraut on the door, as this area is exposed to temperature fluctuations every time the door is opened and closed.

Keep the Liquid Level High

Sauerkraut needs to be submerged in its own liquid to prevent it from drying out and spoiling. If the liquid level drops below the surface of the sauerkraut, add some filtered water or brine (salt water) to cover it. Make sure the liquid is fresh and clean, or it can introduce harmful bacteria.

Check for Mold or Indications of Spoilage

Even if you store sauerkraut properly, it can still spoil if it’s contaminated or exposed to air. Check the sauerkraut regularly for mold, off-odors, sliminess, or discoloration. If you notice any of these signs, discard the sauerkraut immediately.

How Long Can an Open Jar of Sauerkraut Last?

An open jar of sauerkraut can last for 1-2 months in the refrigerator if stored properly. Follow the same storage tips as for unopened sauerkraut. However, keep in mind that once you open the jar, the sauerkraut is exposed to air, which can cause it to lose its flavor and texture over time. To help preserve the sauerkraut, spoon out what you need and replace the lid immediately. You can also transfer the sauerkraut to a smaller container that fits its volume more closely, leaving less room for air.

Can You Freeze Sauerkraut?

You can freeze sauerkraut to extend its shelf life, but keep in mind that freezing can alter its texture and taste. Frozen sauerkraut will be softer and less crunchy than fresh sauerkraut, but it can still be used in cooked dishes like soups, casseroles, and stews. To freeze sauerkraut, transfer it to an airtight container or a freezer bag, leaving some headspace for expansion. Label and date the container, and store it in the freezer for up to 6 months. Thaw the sauerkraut in the refrigerator before using it.
