A comprehensive, step-by-step pictured tutorial on How to Make Sauerkraut that is incredibly healthy and delicious! Making your own fermented homemade sauerkraut is super easy, requires minimal prep work, and the rest is just a waiting game!
Sauerkraut is in my blood. Being from Germany and raised by a health-conscious mom, I ate this stuff on a regular basis. In Germany sauerkraut is eaten fresh or cooked in a wide variety of dishes; everything from casseroles and soups to salads or alongside meats and sausages. Raw fermented sauerkraut was always readily available in our local health food stores. My mom and I regularly went to our local Reformhaus and in the refrigerated section was a large vat of fresh sauerkraut where we could scoop out as little or as much as we wanted into the bags provided. We’d often nibble on some of it as we made our way through the outdoor shopping district and then take the rest home with us. This ancient skill has been making a comeback in recent years both overseas and in the U.S., with a growing number of people learning how to ferment their own foods.
I’ve been fermenting vegetables, grains, legumes, and dairy products for over a decade and it is a deeply satisfying venture. If you’ve been curious about how to make sauerkraut it’s time to make that leap.
For anyone interested in trying their hand at fermentation, sauerkraut is the perfect place to start!
Why Make Your Own Sauerkraut?
The benefits of probiotics are well-established and the fact that you’re here reading this means you’re already aware of that. And you’re probably also aware that there is no better or easier way to access a wide spectrum of probiotics than making your own sauerkraut. With probiotic supplements you’re limited to a couple or few select strains. Research has shown homemade fermented sauerkraut to contain as many as 28 separate and distinct strains. No probiotic pill can replicate that. Not to mention that there is no way to verify how much of the bacteria is even still alive in probiotic supplements.
With homemade fermented sauerkraut you’re benefitting not only from a large variety of probiotic strains, you’re also getting a large dose of live, healthy, and robust ones.
What Equipment Do I Need to Make Sauerkraut?
You don’t need any specialized equipment to make sauerkraut.
- A large glass or ceramic jar
- Some kind of heavy, flat-bottomed tamper for crushing the cabbage
- Something flat to weigh down the cabbage that’s relatively close in size to the diameter of the jar you’re using
- Fresh cabbage
- Salt
That’s it. You don’t need any specialized tools, gadgets, or equipment. People have been successfully making sauerkraut for many centuries using the most basic supplies and chances are you already have what you need on hand and can easily improvise if you need to.
Specialized Sauerkraut Making Equipment (Optional)
Alternatively you can invest in some dedicated equipment, some of which (airlock lids) will make the process more maintenance-free:
- Airlock lids – These lids prevent mold spores/yeasts from getting into the jar so that you don’t have to monitor it as closely or remove mold as it forms. They also automatically release air pressure as the veggies ferment so you don’t have to manually open the jar on a daily basis to release the pressure.
- Sauerkraut Crocks – These come in all difference sizes depending how large of batches you’re making. Some crocks come in a kit with a tamper and weight.
- Sauerkraut Tamper/Pounder – You can find these in wood or stainless steel and they allow you to pound the cabbage to release its liquid and then use it as a tamper for stuffing the cabbing in the jars.
Additional Resources
- The Art of Fermentation by Sandor Ellix Katz – The ultimate guide to fermenting anything and everything, including sauerkraut. It’s my favorite book on the subject and the one I most highly recommend.
How Long Does Sauerkraut Keep?
Stored in a dark, cool place it will keep for many months. The cooler the storage area the longer it will keep. I keep mine stored in the fridge. Even in a cold environment like the fridge, sauerkraut will continue to ferment though at a much slower pace.
Can You Freeze Sauerkraut?
Yes, but just know that it will kill the probiotics. Cooking the sauerkraut will also kill the probiotics. So if your objective is to reap the benefits of the probiotics, eat it raw and unfrozen. If your objective is simply to enjoy it cooked as a delicious food (and delicious it is!), you will still reap the benefits of its vitamins and fiber.
How Long Does it Take to Ferment Sauerkraut?
As long as you want it to until it reaches the desired texture and level of tanginess. Days. Weeks. Months. It will become tangier the longer it sits.
The length of the fermentation time will depend primarily on the temperature of the environment. The cooler the environment, the longer it will take to ferment. The warmer the environment the quicker it will ferment, the flavor will be inferior, and the sauerkraut is at greater risk of developing unwanted yeast and going bad. The ideal temperature for sauerkraut is 65-70 F. At that temperature we recommend letting it ferment for at least 2 weeks (preferably longer) but you can cut it shorter depending on your taste preference.
Can I Make Sauerkraut Without Salt?
While you can make sauerkraut without salt and you can find information on alternatives online, we do not recommend it. Salt is a key ingredient in fermenting foods for several reasons: 1) It creates an environment that favors the formation of lactobacillus bacteria (good bacteria) and prevents unwanted bacteria and yeast from forming, 2) It prolongs the shelf-life, 3) It helps preserve the vitamin and mineral content of the food, 4) It improves the flavor, 5) It helps keep the vegetables crisp and crunchy, and 6) It slows down the fermentation process so that the vegetables can develop a fuller, more complex flavor.
Fermented vegetables, including cabbage, do best with a salt content of 2-3%. Translated in measurements that’s 1 1/2 to 2 teaspoons of salt per pound of cabbage (9-12 grams of salt per 450 grams of cabbage).
Does Sauerkraut Go Bad?
While fermented foods are slower to go bad, they most certainly can and will in time. So how can you tell if sauerkraut is bad? See below.
My Sauerkraut Has Mold on it: Is it Safe to Eat?
In most cases it is perfectly safe. Mold most often occurs when the cabbage isn’t submerged under the brine and comes in contact with air. When this happens it is perfectly safe to remove and discard the top layer of the sauerkraut. This is true if the mold is a greenish or grayish color. If however the mold is black, orange, or pink or if your sauerkraut has changed to an unpleasant color, slimy texture, or bad smell, then toss it.
How to Make Sauerkraut
- Chop the cabbage and place it in a large flat-bottomed bowl.
- Salt the cabbage.
- Pound the cabbage to release its juices.
- Transfer the cabbage to a glass or ceramic jar or crock and use a tamper to push the cabbage down into the jar to remove any air pockets until the cabbage is completely submerged under the brine.
- Place the lid on the jar, put the jar in a cool, dark place, and wait. Remove the lid every day to release air pressure, to make sure the sauerkraut is submerged under the brine.
- Taste the sauerkraut every day after the first few days until it reaches the desired texture and level of tanginess.
- Screw the lid on tight and store your finished sauerkraut in the fridge or a cool cellar.
Let’s get started!
Prepare the Cabbage:
Remove any bruised or damaged exterior leaves from the cabbage, then cut the cabbage in half and remove the core. Slice the cabbage very thinly, approximately 1/8 inch thick. For the best texture we recommend slicing it very thinly by hand, not with a food processor. You can slice it by hand, use a mandolin, or cabbage slicer.
Place the sliced cabbage in a large bowl and toss in the salt. Let it sit for about 20 minutes until the cabbage has begun to wilt and releases some of its juices. Use a tamper/pounder to crush the cabbage until it is wilted and has released a lot of liquid. This will take several minutes.
Pack the Cabbage into a Jar or Crock:
Transfer the cabbage and all the juices to a glass or ceramic jar or crock a bit at a time and mash it down with a tamper. Fill the jar to about 2/3 full (the cabbage will bubble as it ferments and could overflow if the jar is too full).
Continue to mash the cabbage with the tamper, releasing more juice, until the cabbage is completely submerged under the brine.
If you’ve mashed all you can mash and you still don’t have enough brine to cover the cabbage you’ll need to make some supplemental liquid that is consistent with the salinity of the cabbage brine: Dissolve 2 teaspoons of salt in 1/2 cup of water (12 grams of salt in 118 grams of water) and add that to the jar until the cabbage is completely submerged under the liquid.
It’s also important to mash the cabbage to remove any air pockets in order to prevent mold growth.
The prep work is done.
It is imperative that the cabbage remain submerged under the brine during fermentation, otherwise mold will form (See section above “My Sauerkraut Has Mold on it: Is it Safe to Eat?”). To do this choose a heavy object whose diameter is roughly the same size to the inside of the crock you’re using. The object should be glass, ceramic, or non-reactive metal.
Note: I have made sauerkraut multiples times in large mason jars (usually 1/2 gallon size) without needing to use weights. Because of the small diameter of the jar, after a day or two of fermenting the cabbage usually remains below the liquid level. If the cabbage rises above it I just mash it back down with the tamper. If you choose to use mason jars without using something to weigh down the cabbage, just be sure to keep a close eye on it each day throughout the fermentation process.
Let the Fermentation Begin!
Screw on the lids to fingertip tightness. If using airlock lids, follow the instructions provided with your lids.
Place the jars in a dark place that is between 65-70 degrees F, the ideal temperature for fermenting. (See section above “How Long Does it Take to Ferment Sauerkraut” for information on temperature variations.)
Now it’s time to WAIT.
At a the ideal temperature range of 65-70 F we recommend fermenting the cabbage for at least 2 weeks (we recommend longer) but follow your own taste.
After 4 days of fermenting start tasting the cabbage daily until it reaches the desired texture and level of tanginess. Don’t be alarmed if the brine becomes fizzy, this is completely normal and a positive sign of microbial activity.
The color of the cabbage will change from green to a pale yellowish beige (in the pic below compare the green-colored cabbage in the jars, still in the early stages of fermenting, with the finished sauerkraut in the middle).
Once your sauerkraut has reached the level of tanginess that you want, it’s time to screw the lid on tight (remove the airlock lid if using and replace it with a regular lid).
Store the sauerkraut in the fridge or a cold cellar. The storage temp should be between 38-50 degrees F. Fermentation won’t stop but it will be greatly slowed down.
Stored in the fridge the sauerkraut will keep for many months. (See section above “Does Sauerkraut Go Bad?”)
Eat your sauerkraut raw to reap the benefits of the probiotics or use it in any recipe calling for sauerkraut.
Enjoy!

How to Make Sauerkraut
Ingredients
- 1 1/2-2 teaspoons salt for every pound of cabbage (9-12 grams salt per 450 grams of cabbage) (use sea salt, pickling salt, or kosher salt - avoid iodized salt because it can inhibit fermentation and make sure that whatever salt you use contains no anti-caking ingredients)
- very fresh green cabbage (The fresher the cabbage the more juice it will have to make a sufficient amount of brine. The finished sauerkraut will also have a much better texture.)

Ivan Lotter says
Hi,
Nowhere does it say how to prepare the brine. Does the mashing create the brine, i.e. Cabbage Juices and Salt that was added?
Regards
Ivan
Kimberly @ The Daring Gourmet says
Hi Ivan, yes that’s correct, the brine is produced by mashing down the cabbage. In Step 2 I provide instructions for how to create a salt brine if you need additional liquid beyond what mashing the cabbage produces.
Dan says
Yes
You can add salted water to the cabbage. 2tbsp/cup water. Use kosher salt
Mahsa says
I made it for the first time following this recipe. After 10 days the result is perfect. No weight used
Kimberly @ The Daring Gourmet says
I’m so glad it was a success, Mahsa, thank you!
Kris says
Can you use red or purple cabbage?
Kimberly @ The Daring Gourmet says
Yes you can, Kris. It’s a little sweeter than green cabbage and has a beautiful color. It’s a fun way to change things up.
Julia Sidorov says
Hello, I followed this recipe and used mason jars. I am wondering if I need to “burp” them every day? The brine is covering the cabbage and it seems to be doing well. It’s been 1 day. It does look like some air built up under the lid, should I release it? Thank you for your time.
Kimberly Killebrew says
Hi Julia, yes that is correct. The part about releasing the air is in Step 3: “Note: If you’re not using an airlock lid be sure to open the lid of your jar/crock every day to release the pressure and prevent your jar from exploding.” The amount of air building up will subside over time and it won’t be necessary to release it every day, you’ll just want to keep an eye on it.
Sanjiv says
Very interested in trying out this recipe. A few questions
1. Seems like the plastic bags with water are not recommended. Is there a shop or some other solution for the weight on the cabbage?
2. What does finger right mean when screwing on the cap?
Kimberly Killebrew says
Hi Sanjiv, many people use the plastic bag method and as long as it’s food grade plastic it probably really is fine. Otherwise you can get creative with any objects you have around the house that won’t corrode with exposure to salt – like a large ceramic mug or a small dessert plate that you can lay on the surface and weigh down with a glass filled with water, etc. Finger tight simply means not screwing the cap on really tight – just screw it on lightly.
Lewis Schwartz says
I live n Arizona and can’t store jar in 60-75 F, house in summer usually @ 82F.
Can I ferment in the refrigerator?
Kimberly Killebrew says
Hi Lewis, unfortunately no. The fridge is generally between 36 and 38 F which is too cold for fermentation to effectively take place.
Chris Martinelli says
Use a large cooler and put a cup of ice or 2 in it and keep changing it out every morning and evening, and it will keep at the proper temperature… I’m in arizona too and I make kraut and Kimchi all year round like this.
Cathy says
I put the jar in a few layers of insulation, (e.g. a towel and a thermal bag with a reflective layer) then move it in and out of the fridge every few hours. I can feel the jar to check that it’s cool and has not come up to room temperature, to figure out how often I need to move it. During the day I have it in the fridge for shorter times and out for longer times, as I think the recommended temperature is closer to room temperature than to the fridge temperature; so maybe an hour in the fridge then a few hours out. At bedtime I put it in the fridge. I figure it’s OK if it spends a longer time in the fridge where it might ferment slowly (according to some sources) or take a break from fermenting; but not OK to spend too long out of the fridge. If I happen to wake up during the night I’ll move it out or in.
By the way, I also add a bit of leftover sauerkraut that I save from the previous batch, to get the bacteria started. This seems logical to me but may have advantages and disadvantages. I need to watch out that I don’t get unwanted microorganisms in there.
Linda Deiter says
Can you use a crock with a lid that just sets on top such as a crock pot with a glass lid?
Kimberly Killebrew says
Hi Linda, the challenge with the crock pot with the glass lid is the seal, or rather the lack thereof, which will expose the kraut to the air and increase the potential for contamination. If you’re diligent about ensuring the cabbage is kept fully immersed under the brine at all times you limit the exposure, but I still recommend using something with a lid that’s more secure.
Susan Simpson says
Can you add vinegar to the cabbage? For some reason I always thought there was vinegar was in sauerkraut.
Kimberly Killebrew says
Hi Susan, vinegar is added when manufacturers don’t take the time/follow the process to actually ferment the sauerkraut (it’s their effort to try and replicate the tangy flavor). This recipe is for making real, naturally fermented sauerkraut the traditional way. No vinegar is added.
Cindy Winter says
I made your recipe and loved how simple it was! Plus a recipe for extra brine. I don’t think I made sure to get all the air out after adding some brine. It’s been 3 days, can I open it up and push everything down to make sure all the air is out?
Kimberly Killebrew says
Hi Cindy, yes you can do that, no problem. Just be sure to use a clean, sterilized spoon to avoid introducing any contaminants.
Wm Weber says
We made Kraut in 25 gal. Crocks. Buy Kraut cabbage, 1/4 each head. Place into a hand shredder. Layer 8 inches each lift. Beat with our hand to produce liquid thru each layer up to desired level. Salt was added at each lift, periodically mustard seed were added, also a clove of garlic periodically. Once complete a wood “Lid” laid on top then a gal of water added for weight and covered with a cheese cloth. Then wait, taste periodically. Once met, then packed on quart jars. 50% given family and friends. I loved a large dish with Kraut cover with pork ribs and baked. Also as a raw snack.
William
Kermit R Johnson says
My mother made Sour kraft when I was A boy. She. Always sterilized. Her jars then stuffed the scheredded cabbage into jars. Added 1tbs canning salt then Poured boiling water to the top of jars. put on lid and waited for fermentation process.
Rebecca P says
i just tasted the product on day 3 & its very salty, is this normal?
Kimberly Killebrew says
Hi Rebecca, how much salt to use is very subjective and there’s a range of how much salt you can use to prepare sauerkraut depending on your preference. The first round of sauerkraut will inform your subsequent batches and whether you want to increase or decrease the salt content.
Sarah says
Hi! Do you mean that you should eat sauerkraut cold in order to get the prebiotic benefits? We’ve always heated it up on the stove with sausages or pork chops…
Kimberly Killebrew says
Hi Sarah, no, prebiotics will survive the cooking process. I’m referring to probiotics which are living microorganisms (ie, healthy bacteria) and they are destroyed once the temperature reaches 115 degrees F. So in order to benefit from probiotics foods must be consumed raw/unheated.
Maryellen says
It was suggested to me to fill a sandwich bag with 2/3 water, seal and cover the top of the cabbage, until it is submerged (I use Mason jars). The weight of the water will keep the brine over the cabbage. This has worked well for me and it allows gases to escape.
Kimberly Killebrew says
Hi Maryellen, yes, that is a method I know a lot of people use and it does work to keep the cabbage submerged. I just personally prefer to avoid any contact with plastics when it comes to the fermentation process. I know food grade plastic is considered safe but I’m still cautious when it comes to acids.
Laura says
Can this kraut be water bath canned once it’s done fermenting so it will stay shelf stable longer?
Kimberly Killebrew says
Hi Laura, this hasn’t been tested for canning and I doubt the pH level is sufficiently acidic to be safe for water bath canning.
Deb says
Hi Laura we have been making sauerkraut for years and we can it in pint jars. We heat it on the stove and put into hot jars and cap just like any canning method. I don’t use a water bath but you probably can. Ours last at least a year until our next batch is made.
Leanne says
Do you need to sterilise the jar ?
Kimberly Killebrew says
Hi Leanne, I always sterilize jars when I’m canning for long-term storage. For sauerkraut I don’t usually bother. But if it will give you peace of mind it never hurts to take the additional step.
