How To Store Homemade Sauerkraut

If you are a fan of sauerkraut, then you know that there is nothing quite like the taste of homemade sauerkraut. However, once you have made your batch, it is important to store it properly to keep it fresh and tasty.

The good news is that storing homemade sauerkraut is easy if you follow a few guidelines. Firstly, understanding the basics of sauerkraut storage is key. Sauerkraut needs to be stored in an environment where it can continue to ferment slowly.

This means that it needs to be kept at a cool temperature, away from direct sunlight and heat sources. In addition, the container used for storage plays an important role in preserving the freshness of your homemade sauerkraut.

By following these tips and tricks for storing homemade sauerkraut, you’ll be sure to enjoy its tangy flavor for months to come!

Understand the Basics of Sauerkraut Storage

You’re gonna want to make sure you store your homemade sauerkraut properly if you don’t want all that hard work to go to waste! The first step in understanding the basics of sauerkraut storage is knowing that it needs to be kept in a cool, dark place. Ideally, you’ll store it at around 40-45°F (4-7°C). This will help slow down the fermentation process and keep your sauerkraut fresh for longer.

Another thing to consider when storing your homemade sauerkraut is flavor variations. Sauerkraut can have a range of flavors depending on how long it’s been fermented, the type of cabbage used, and any additional seasonings or ingredients added.

Storing your sauerkraut in different ways can affect its flavor as well. For example, if you prefer a sweeter taste, store your kraut at room temperature for a few days before transferring it to the fridge. And let’s not forget about the health benefits – proper storage ensures that your homemade sauerkraut stays full of beneficial probiotics and nutrients.

Choose the Right Container

When choosing a container for your homemade sauerkraut, there are three key points to consider: materials, size and shape, and sealability.

Firstly, you’ll want to choose a food-grade container that won’t react with the acidic environment of your kraut.

Secondly, the size and shape of your container will depend on how much kraut you’re making and how much storage space you have available.

Lastly, make sure your container has a good seal to prevent air from getting in and spoiling your kraut.

Keep these tips in mind when selecting the perfect vessel for fermenting your sauerkraut!

Materials to Consider

One must consider the type of container they’ll use when storing homemade sauerkraut. The materials used in the container can affect the quality and taste of your sauerkraut.

Here are some materials to consider:

  1. Glass jars – These are a popular choice for storing sauerkraut as they’re non-reactive, easy to clean, and allow you to see what’s inside.

  2. Ceramic crocks – Fermentation crocks specifically designed for fermenting vegetables like sauerkraut can be a good option if you want larger batches and have enough space in your kitchen.

  3. Stainless steel containers – These are durable and non-reactive, but can be expensive compared to other options.

  4. Vacuum sealers – If you want to store your sauerkraut for longer periods of time, vacuum sealing is an effective method that removes all air from the container.

Consider what factors matter most to you when selecting a storage container for your homemade sauerkraut. Each material has its own advantages and disadvantages, so choose one that fits your needs best.

Size and Shape

Considering the size and shape of your container can impact the overall fermentation process and flavor profile of your kraut. Different container types, such as mason jars or crocks, come in various sizes and shapes that can affect how quickly the kraut ferments.

A smaller jar may ferment faster than a larger one because there’s less oxygen present to slow down the process. Similarly, a wider vessel with more surface area exposed to air may cause the kraut to dry out or develop mold if not properly monitored.

When choosing a fermenting vessel for your sauerkraut, it’s important to consider its size and shape in relation to the amount of cabbage you are using. If you have a large head of cabbage, you’ll need a bigger container to accommodate it all. However, if you’re making small batches for personal use, then smaller jars may be more practical.

Additionally, considering the shape of your container can help ensure even fermentation throughout all layers of cabbage and prevent any unwanted air pockets from forming. Ultimately, selecting an appropriate container for your homemade sauerkraut can make all the difference in achieving optimal flavor and texture results.


The sealability of your fermenting vessel can impact the success of your kraut by keeping out unwanted air and bacteria. When choosing a container for your homemade sauerkraut, it’s important to look for one that has a tight-fitting lid or cover.

A well-sealed container will create an anaerobic environment that’s essential for the fermentation process. Here are some benefits of fermentation to keep in mind when considering the sealability of your container:

  • Fermentation preserves nutrients and increases their bioavailability
  • It boosts gut health by introducing beneficial probiotics
  • Homemade sauerkraut contains more live cultures than store-bought varieties

In addition to these benefits, it’s also important to consider the difference between homemade and store-bought sauerkraut when choosing a container with good sealability. While store-bought kraut may come in vacuum-sealed packages or cans, homemade kraut requires an airtight vessel that allows for gas exchange during fermentation.

By ensuring proper sealability, you can enjoy all the benefits and flavor of homemade sauerkraut without any unwanted contaminants.

Properly Seal and Label Your Sauerkraut

To ensure your sauerkraut stays fresh, it’s crucial to seal and label the jars properly.

First off, make sure the lids are tightly sealed to prevent any air from entering the jar. You can check if a jar is properly sealed by pressing down on the center of the lid; if it doesn’t pop back up, then you’ve achieved a good seal.

When labeling your jars, include important information such as the date of fermentation and any additional ingredients added. This will help you keep track of how long your sauerkraut has been fermenting and what flavors or spices were used in case you want to recreate it in the future.

Additionally, consider using DIY fermentation weights to ensure that all of your cabbage is submerged in its brine and reduce the risk of mold growth.

With proper sealing and labeling techniques, you can enjoy homemade sauerkraut for months to come!

Store Your Sauerkraut in a Cool Place

Now that you’ve properly sealed and labeled your homemade sauerkraut, it’s time to talk about storing it in a cool place. You have a few options for this – refrigeration is the most common and convenient method, but if you have access to a root cellar or other cool storage options, those can work too.

In this discussion, we’ll go over the benefits and drawbacks of each option so you can choose the best one for your situation.


Refrigerating your homemade sauerkraut is crucial for maintaining its flavor and preventing spoilage because it slows down the fermentation process, ultimately extending the shelf life of your sauerkraut. Without proper storage in the refrigerator, your sauerkraut can quickly become over-fermented and develop an unpleasant odor or taste.

To ensure that your homemade sauerkraut stays fresh, follow these simple steps:

  • Transfer it to an airtight container: Once you’ve finished fermenting your sauerkraut, transfer it into a clean glass jar or a food-grade plastic container with an airtight lid. This will help keep out any excess air that can cause further fermentation.

  • Keep it in the refrigerator: Place your container of sauerkraut on one of the shelves in your refrigerator where it can stay cool and dry. Avoid storing it on the door as this area experiences temperature fluctuations every time you open and close the fridge.

By taking care to refrigerate your homemade sauerkraut properly, you’ll be able to enjoy its tangy flavor for weeks or even months after making it. If you’re looking for alternative preservation methods, there are also ways to freeze or can your sauerkraut for even longer storage options.

Root Cellar

Imagine having a cool and dark space in your home to keep your vegetables fresh for months on end – that’s the magic of a root cellar.

A root cellar is an underground storage area that works by utilizing the natural coolness and humidity of the earth to preserve produce. This method has been used for centuries and is still popular today due to its many benefits.

One of the main benefits of using a root cellar is preserving produce without electricity or refrigeration. The consistent temperature, usually around 50-60°F, helps slow down the ripening process and prevents spoilage. The high humidity also keeps vegetables from drying out while maintaining their freshness.

Root cellars are especially beneficial for storing root vegetables like carrots, potatoes, onions, and beets which can last up to several months in this environment. With proper ventilation and organization, you can have access to fresh produce year-round simply by utilizing a small portion of your basement or digging one into your backyard.

Other Cool Storage Options

You can easily keep your produce fresh without using a refrigerator by exploring other cool storage options available to you. One alternative to storing sauerkraut in a root cellar is by using mason jar alternatives. While glass jars are the most common way of storing fermented foods, ceramic containers or stoneware crocks can also be used. These materials provide better insulation and protection against light and air, which can affect the quality of your homemade sauerkraut.

Another option is to use DIY fermentation crocks. These containers come in various sizes and shapes that allow for more efficient and controlled fermentation of your sauerkraut. They have weights or stones that help keep the cabbage submerged in its own brine, which aids in keeping out harmful bacteria while promoting lactic acid fermentation. With proper care and maintenance, these crocks can last for years, making them a great investment for any home fermenter.

By exploring these different storage options, you’ll be able to enjoy fresh and flavorful sauerkraut all year round without relying on electricity or refrigeration.

Monitor Your Sauerkraut’s Quality and Shelf Life

Now that your sauerkraut is stored in a cool place, it’s important to keep an eye on its quality and shelf life. You’ll want to watch for any signs of spoilage, such as mold or a foul odor.

Generally, homemade sauerkraut can last up to six months in the fridge, but there are creative ways you can use up any leftovers before they go bad.

Signs of Spoilage

If your sauerkraut has a slimy texture or a foul odor, it may have spoiled and should be discarded. Spoilage can occur due to potential causes like improper storage, contamination during the fermentation process, or using old vegetables. To prevent spoilage, make sure to use fresh vegetables and sterilize all tools and containers before beginning the fermentation process. Additionally, store your sauerkraut in a cool and dark place, away from direct sunlight.

Here are four signs of spoilage that may evoke an emotional response in you:

  1. Mold – seeing mold on your sauerkraut can be disgusting and off-putting.

  2. Discoloration – if your sauerkraut has turned brown or black instead of its usual light green color, it’s likely gone bad.

  3. Sour smell – while fermented foods tend to have a sour smell, if it smells particularly unpleasant or rancid, it’s time to throw it out.

  4. Slimy texture – touching slimy sauerkraut is sure to make anyone feel uneasy.

By paying attention to these signs of spoilage and taking preventative measures during the fermentation process and storage of homemade sauerkraut, you can ensure that your batch stays fresh for as long as possible.

Expected Shelf Life

It’s important to know the expected shelf life of your sauerkraut, so you can enjoy it at its best before it goes bad. Factors affecting the longevity of homemade sauerkraut include temperature, storage conditions, and the quality of ingredients used. Typically, homemade sauerkraut can last up to six months in a properly sealed container and stored in a cool, dark place.

To prolong the shelf life of your sauerkraut, there are some tips you can follow. First off, make sure that all utensils and containers used for making or storing sauerkraut are clean and sterilized.
