When it comes to fermented foods, sauerkraut is one of the most popular and widely consumed options. Made from finely shredded cabbage that has been fermented in its own juice, sauerkraut is a tangy, crunchy, and flavorful condiment that can add a burst of flavor to a variety of dishes. But, like any fermented food, sauerkraut has a limited shelf life, and its storage and handling are crucial to maintaining its quality and safety. In this article, we’ll explore the topic of how long sauerkraut will keep in the refrigerator, and provide some valuable tips on how to store and handle it to ensure it stays fresh and delicious for as long as possible.
Understanding Sauerkraut’s Shelf Life
Sauerkraut is a fermented food, which means that it contains live cultures of bacteria and yeast that are responsible for its characteristic flavor and texture. These microorganisms are sensitive to temperature, humidity, and oxygen, which can affect their activity and the overall quality of the sauerkraut.
The Factors That Affect Sauerkraut’s Shelf Life
Several factors can impact the shelf life of sauerkraut, including:
- Storage Temperature: Sauerkraut should be stored in the refrigerator at a temperature of 39°F (4°C) or below to slow down the fermentation process.
- Humidity: Sauerkraut should be stored in an airtight container to prevent moisture from entering and causing spoilage.
- Oxygen: Sauerkraut should be stored in a container that is impermeable to oxygen to prevent the growth of unwanted bacteria and mold.
- Handling: Sauerkraut should be handled carefully to prevent contamination and spoilage.
How Long Will Sauerkraut Keep in the Refrigerator?
The shelf life of sauerkraut in the refrigerator will depend on several factors, including the quality of the sauerkraut, the storage conditions, and the handling practices. Generally, sauerkraut can keep for several months to a year or more when stored properly. Here are some guidelines:
| Storage Conditions | Shelf Life |
|---|---|
| Refrigerated at 39°F (4°C) or below, in an airtight container | 6-12 months |
| Refrigerated at 39°F (4°C) or below, in a semi-airtight container | 3-6 months |
| Refrigerated at room temperature (around 68°F or 20°C), in an airtight container | 1-3 months |
Signs of Spoilage
Sauerkraut can spoil if it is not stored properly or if it is contaminated with bacteria or mold. Here are some signs of spoilage to watch out for:
- Off Odor: Sauerkraut that has gone bad will have a strong, unpleasant odor.

How do I make sauerkraut at home?
To make sauerkraut at home, you’ll need a few simple ingredients, including cabbage, salt, and water. Simply shred the cabbage, mix it with salt and water, and pack it into a jar. Leave the jar at room temperature for several days to allow the fermentation process to occur, then store it in the refrigerator to slow down the fermentation process.
Can I use sauerkraut as a substitute for other fermented foods?
Yes, sauerkraut can be used as a substitute for other fermented foods, such as kimchi or sauerkraut. However, keep in mind that each fermented food has its own unique flavor and texture, so you may need to adjust the recipe accordingly.
