Step-By-Step Guide to Canning Sauerkraut
Now, let’s break down the canning process into bite-sized steps. Follow this guide carefully, and you will end up with delicious, homemade sauerkraut ready to store.
1. Prepare the Cabbage
Begin by removing any wilted or damaged outer leaves of your cabbage. Then, slice the cabbage into thin shreds. The thinner the shreds, the better the fermentation process. Place the shredded cabbage in the large mixing bowl.
2. Salting the Cabbage
Sprinkle the non-iodized salt over the shredded cabbage. At this stage, you can also add optional spices, such as caraway seeds or juniper berries, if desired.
Work the salt into the cabbage by kneading it with clean hands for about 5-10 minutes. This process releases the natural juices from the cabbage, creating a brine. The mixture should become wilted and juicy—this is where flavor and fermentation begin.
3. Packing the Jars
Once the cabbage has softened, it’s time to pack it into sterilized Mason jars.
-
Start by filling each jar with the cabbage mixture, pressing down firmly to eliminate air pockets. Aim to leave about an inch of headspace at the top of the jars.
-
Pour any excess brine into the jars, ensuring that the cabbage is fully submerged. This will help prevent spoilage during the fermentation process.
-
Use a bubble remover or a clean knife to carefully poke around the sides of the jar to release any trapped air bubbles. This step is crucial for proper fermentation.
-
Wipe the rims of the jars with a clean cloth to remove any residue, ensuring a good seal with the lid.
4. Sealing the Jars
Now, place the sterilized lids on each jar and screw on the metal bands until they are fingertip-tight. Do not over-tighten as this can prevent steam from escaping during the canning process.
5. Preparing the Pressure Cooker
Fill your pressure cooker with about 2 inches of water, and set the temperature to high. Follow the manufacturer’s instructions for your specific pressure cooker model.
6. Canning Process
Once the water is boiling, carefully place the jars in the pressure cooker. If your pressure cooker can hold multiple jars, stack them carefully to ensure each jar receives adequate steam.
Seal the pressure cooker lid securely and bring the pressure to 10-15 pounds, depending on the jars’ specifications. For most Mason jars, a pressure of 10 pounds is sufficient.
Process the sauerkraut for approximately 15-20 minutes, adjusting for altitude as needed:
- 0–1,000 feet: 15 minutes
- 1,001–3,000 feet: 20 minutes
- 3,001–6,000 feet: 25 minutes
After the processing time is complete, turn off the heat and allow the pressure to come down naturally. This crucial step allows the jars to cool slowly and helps prevent accidents.
7. Cooling and Storage
Once the pressure cooker is cool, remove the lid carefully. Use the jar lifter to transfer the jars to a cooling rack or counter. Be sure to place them in a location away from drafts. Allow the jars to cool completely for 12-24 hours. During this time, you may hear the satisfying “pop” as the seals form.
After cooling, check the seals by pressing down in the center of each lid. If it does not pop back, the jar is sealed properly. Any jars that did not seal should be refrigerated and consumed first.
Store the sealed jars in a cool, dark place such as a pantry or cellar. The sauerkraut will continue to ferment and develop its flavors over time. It can last for up to a year when stored correctly.
Tips for Success
Successfully canning sauerkraut takes practice. Here are some tips to enhance your canning experience:
Choose the Right Cabbage
For the best flavor and texture, opt for fresh green cabbage, Napa cabbage, or even red cabbage for a colorful twist. Organic cabbage often yields more vibrant flavors.
Monitor Your Fermentation
Fermentation can vary based on room temperature. Cooler environments promote slower fermentation, while warmer conditions speed it up. Always taste a bit of your sauerkraut during the process to find your ideal level of tanginess.
Experiment with Flavor
Don’t hesitate to customize your sauerkraut. Experiment with added ingredients, such as shredded carrots, beets, or various spices, to create your signature blend.
Enjoying Your Sauerkraut
Once you’ve canned your sauerkraut, the possibilities are endless! It pairs beautifully with:
- German sausage: Serve alongside bratwurst or kielbasa for a classic meal.
- Sandwiches: Use as a topping for Reubens or pulled pork sandwiches.
- Salads and bowls: Toss it in with grains, greens, and other veggies for a delicious crunch.

What is the best type of cabbage to use for making sauerkraut?
The best type of cabbage for making sauerkraut is green cabbage, as it has the ideal balance of sweetness and crunch. Varieties such as Savoy or even red cabbage can also be used for added color and unique flavors, but green cabbage remains the traditional choice. Look for fresh heads of cabbage that are firm and free from blemishes. Freshness is crucial, as older cabbage may lack the ability to ferment properly.
Aside from the cabbage variety, the quality of the cabbage is essential as well. Organic cabbage is often recommended since it tends to have a more robust flavor and is free from pesticides and chemicals. Always wash the cabbage thoroughly to remove any dirt or residual pesticides before starting your canning process.
Do I need to add any other ingredients besides cabbage for canning sauerkraut?
While the primary ingredient for sauerkraut is cabbage, you can enhance its flavor by adding coarse sea salt. A common ratio is about 3 tablespoons of salt for every 5 pounds of shredded cabbage. This salt helps to draw water out of the cabbage, starting the fermentation process and creating a flavorful brine. Some recipes may suggest adding shredded carrots, spices like caraway seeds, or even garlic for a unique twist on the traditional flavor.
However, it’s crucial to ensure that you do not add any preservatives or oils, as these can interfere with the fermentation process and potentially spoil the sauerkraut. The goal is to keep the ingredients simple to let the natural flavors shine through while also creating a safe and delicious end product.
How long should I ferment sauerkraut before canning it?
The fermentation time for sauerkraut can vary, typically ranging from 1 to 4 weeks, depending on your taste preference and the fermentation temperature. A warmer environment speeds up fermentation, while a cooler room may slow it down. It’s advisable to start tasting the sauerkraut after one week to determine its flavor and crunchiness; many prefer a tangy flavor that develops around the two-week mark.
During fermentation, ensure that the cabbage stays submerged in the brine, as this prevents unwanted mold from forming. If necessary, you can use a fermentation weight or a clean, heavy object to ensure that the cabbage is fully submerged. Once you’re satisfied with the flavor, it’s time to move on to the canning process.
Can I can sauerkraut directly in the pressure cooker?
Canning sauerkraut directly in the pressure cooker is not recommended. Instead, you should first ferment the cabbage and prepare it in a separate container. After the fermentation process, you can use the pressure cooker to sterilize the jars and seal them properly. The canning process requires specific temperatures and times that are generally achieved by using a water bath or a pressure canner, which helps preserve the sauerkraut for long-term storage.
After the fermentation is complete, pack the sauerkraut into sterilized jars, leaving some headspace, and then process them in the pressure cooker. This method ensures that your sauerkraut maintains its flavor and texture while being safely preserved for future use.
How long can I store canned sauerkraut?
Canned sauerkraut can typically be stored for up to a year if kept in a cool, dark, and dry place. After this period, while it may still be safe to eat, the flavor and texture can begin to deteriorate. It’s recommended to label your jars with the date of canning to keep track of their shelf life. Always inspect the jars before consumption; if you notice any signs of spoilage, such as an off smell or fizzing when opened, it’s best to discard it.
When it comes to storing your canned sauerkraut, ensure that the lids are still sealed properly. A properly sealed jar will have a slight indent at the center of the lid. If you press the lid and it pops back, that means the jar is not sealed, and refrigeration is necessary. Proper storage and handling can significantly extend the life of your canned sauerkraut.
Can I use a regular pot instead of a pressure cooker for canning sauerkraut?
You can use a regular pot, such as a large stockpot, for canning sauerkraut, but it must be equipped to handle water bath canning rather than pressure canning. Water bath canning is suitable for high-acid foods like sauerkraut, which can be processed at boiling temperatures (212°F or 100°C). If you choose this method, ensure your pot is deep enough to allow water to flow over the jars by at least an inch during the boiling process.
However, if you’re using a pressure cooker specifically designed for pressure canning, it provides a more controlled environment and is often recommended for preserving low-acid foods. Although sauerkraut is high in acidity, using a pressure cooker can expedite the processing time and ensure a safe seal. Be sure to follow the manufacturer’s instructions for canning in any pot you decide to use.
What are the potential safety risks of canning sauerkraut?
When canning sauerkraut, it’s vital to adhere strictly to safety guidelines to avoid foodborne illnesses. The primary risks are under-processing, which may lead to spoilage, and the possibility of botulism if improper canning methods are used. Botulism is a rare but serious illness resulting from the bacteria Clostridium botulinum, which can thrive in an improperly sealed or low-acid food environment.
To mitigate these risks, ensure that you follow a tested recipe and strictly monitor processing times and temperatures. Additionally, always check your jars for proper seals before storing them. If you notice any jars that are not sealed or show signs of spoilage, do not consume them. Proper attention to safety during the canning process is crucial for enjoying your homemade sauerkraut without health concerns.
Can I freeze sauerkraut instead of canning it?
Yes, sauerkraut can be frozen instead of canned, which is a great option if you’re looking to preserve it for a shorter term or prefer not to go through the canning process. Freezing sauerkraut is easy and can help maintain its flavor and texture for up to 8 to 12 months. To freeze, simply pack the fermented sauerkraut into freezer-safe bags or containers, leaving some room for expansion as it freezes.
However, keep in mind that freezing changes the texture slightly, making it softer upon thawing. This change may not be significant for cooked dishes where sauerkraut is blended into recipes, such as soups or casseroles. But if you enjoy sauerkraut raw or want to use it in salads, it’s best to stick to canning for the best overall crunch and quality.
