How to Ferment Cabbage and Make Sauerkraut

How to Ferment Cabbage and Make Sauerkraut on #homemade #cooking #tutorial

A few months ago I wrote up a short post on a new food “trend” with ancient roots – fermentation. Many of you expressed interest in learning more about the process. I’m no fermentation expert… in fact, I’ve never done any fermenting at home before, but I’ve been wanting to try it. Your interest inspired me. For my first fermentation adventure, I decided to take a crack at the most basic fermented food – homemade sauerkraut. With the help of my trusty kitchen buddy/assistant Ashley and her boyfriend Gary (who happens to be a super talented, farm trained, do-it-yourself culinary school grad with lots of fermenting experience), we made our way through the first half of the fermentation process.

Sauerkraut, a combination of the southern German and Austrian words “kraut,” meaning cabbage, and “sauer” meaning sour, literally translates to sour cabbage. It is created by fermenting cabbage over a long period of time. There are several health advantages to homemade sauerkraut. It’s high in enzymes and vitamin C, both of which are lost during the heating and pasteurization of store-bought sauerkraut. It’s also low calorie and easy to digest. As I was learning about the fermentation process, I became curious about the difference between fermenting and pickling. The most obvious difference is that fermentation creates acid, while pickling requires an added acid, for example vinegar. Both serve as a preservation technique, the science is just a bit different.

Sauerkraut takes about 4-6 weeks to make. Since it’s a “hurry up and wait” kind of thing, I am documenting the adventure here on my blog. I will walk you through what we did, step-by-step, so you can try it at home. You might want to wait a few weeks to see how our fermented cabbage turns out before you take a crack at it yourself. I will post the results here on the blog. We did everything “by the book,” so fingers crossed it will all turn out delish!!

First thing’s first– we bought a crock. A big, honking fermentation crock. It really looked so much smaller online. At first, I was dismayed. After the initial shock wore off, I decided the size was a plus… it means you can make a large batch of fermented veggies at the same time. With the amount of time it takes to ferment, why not make a big batch that will last you several months? And I do mean a big batch. We sliced up enough cabbage to create a decade’s supply of sauerkraut. Seriously.

Here’s the crock in all its crock-ish glory, along with Gary and Ashley, my fearless sidekicks. Aren’t they cute?

If you too would like to be the proud owner of a ginormous fermenting crock, click here to check out the one I’m using. Keep in mind that it’s pretty heavy/substantial and kind of awkward to handle. It also comes in a smaller size, which is likely a lot more manageable. There’s an even larger size, but really?? That would require some serious fermentation love. You will also need a set of weights to help weigh down the food you are fermenting within the crock. We used 10-15 liter stone weights; for a smaller crock, use 5 liter weights.

Crocks can be a bit pricey, so if you’d rather not invest in one, there are some less expensive options. You can use just about any container, taller than it is wide, made from enamel, ceramic or food grade plastic. Once you have chosen your vessel, find a plate that will cover the majority of the cabbage. To make sure that the cabbage stays submerged in the brine, a key component of fermentation, you will need to make a weight to place on top of the plate. The simplest option is to place plastic storage bags filled with salt water on top. You can then cover your container with plastic wrap or a lid.

Once we cleaned out the crock, we got to work. With Gary and Ashley’s help and experience, I felt more confident in outlining the process for you here. I’ll check back with you in a few weeks and let you know how our sauerkraut turned out. Meanwhile, here are a few books that helped us learn the basic fermentation process:

The Preservation Kitchen

Preserving Food Without Freezing or Canning

Since I’m fairly new to fermentation, I decided to start with a basic sauerkraut, which only requires salt, cabbage, and water. Spices can be added to make a flavored sauerkraut or kimchi. If you feel like experimenting, the same method can be used for other vegetables, including cucumbers, onions, beets, carrots, kohlrabi, red cabbage, and rutabaga. You can even combine a variety of vegetables in a kraut medley if you’re really feeling adventurous.

Have you tried fermentation before? Did it turn out the way you hoped it would? What is your favorite fermented food?

UPDATE: Our kraut turned out great! It took about 5 weeks to achieve the flavor and texture I was going for. This sauerkraut was so much better than the store-bought kind… it was salty, pungent and the lactic acid made it tingle on my tongue. It’s delicious and way cheaper than store-bought probiotics. Good for your gut, good for your tastebuds… can’t beat that!

How to Ferment Cabbage and Make Sauerkraut

You will need

  • Fermentation crock
  • Cabbage - amount varies based on your needs (we used 3 large heads)
  • Large mixing bowl
  • Kosher salt
  • Kitchen scale
  • 2 fermentation weights
  • Medium saucepan
Prep Time: 20 Minutes
Servings: Varies
Kosher Key: Pareve
  • Before we start, a few pointers. Because fermentation can get a little messy, it’s important that every utensil, towel and piece of food that you use is very clean. You do not want to add any unwanted bacteria to your sauerkraut. We only want the good, pro-biotic kind. When making your own sauerkraut, or doing fermentation of any kind, it’s important to keep in mind that this is an ancient process, developed long before sanitizing cleansers and refrigeration. It’s likely that a small amount of mold or yeast buildup will develop on the top layer of your sauerkraut. This is part of the process and is not a cause for concern. This can be easily removed without coming into contact with your sauerkraut if you place whole leaves on the top of your shredded cabbage, which will create a protective barrier that can easily be removed at the end of the fermentation process. Instructions below.
  • Start by boiling 6 cups of water with 1 tbsp of kosher salt till salt is dissolved. Allow to cool.
  • Meanwhile, clean your cabbage and pull off 5-6 of the external whole leaves, set aside. Shred the remaining cabbage - for instructions on shredding cabbage, click here.
  • Cover the bottom of your fermenting pot with 3-4 whole cabbage leaves. You will only need two layers of whole leaves in the crock, one on the bottom and one on the top.
  • You will need to salt the shredded cabbage before adding it to the fermentation pot. We found this is easiest to do in smaller batches, to keep the salting amount consistent and mixed throughout the fermentation crock. Measure out 2 pounds of shredded cabbage into a bowl (we zeroed our scale with the bowl on, then measured a 2 pound batch).
  • Use clean hands to toss the shredded cabbage in the bowl with 1 tsp kosher salt.
  • Place the salted, shredded cabbage into the fermentation pot on top of the whole leaves.
  • Measure out another 2 pounds of the shredded cabbage and mix with 1 tsp of salt, then add to the fermenting pot. Repeat this process in batches until all of your shredded cabbage has been salted and added to the pot. Pack down the cabbage tightly, but do not crush the cabbage strips.
  • Cover the top of your shredded cabbage with remaining whole cabbage leaves. These leaves will help to collect the yeast and mold that may accumulate at the top of the crock, and can easily be removed and discarded after the fermentation process is complete.
  • Place stone fermentation weights on top of the whole cabbage leaves and press down, but not too hard. You don’t want to damage the cabbage.
  • Cover the fermentation crock with a lid. The salt will naturally draw some water out of the cabbage. After a few hours, check to see how much liquid has accumulated inside of the pot. It should be about 1-3 inches above the cabbage. If this hasn’t happened, add cooled, boiled salt water to the pot. We ended up needing about 3-4 cups of salt water. Pour it over the cabbage till it is submerged (you may not need to do this if your cabbage has created enough natural liquid). Reserve the remaining salt water.
  • Once the water level is where it should be, cover the pot and fill the channel around the lid with cooled salt water to create an airtight seal. This will keep oxygen out of the pot. Once this has been done, do not open the fermentation pot for at least 2 weeks. No peeking! Reserve the remaining salt water brine in a sealed container in the refrigerator; you will need it over the course of the next several weeks.
  • For the first few days, store the pot in a warm place, between 68 and 72 degrees. After a few days have passed, listen for a fizzy, bubbling sound coming from the pot. This is good and means that fermentation has begun. If you don't hear anything, don't worry, it may just mean that the walls of your crock are too thick for sound to travel through. After fermentation has started, move the pot to a cool place, between 59 and 64 degrees, for the remaining fermentation time. If you don't hear anything after 1 week, go ahead and move the crock to a cooler location without waiting for it to sound bubbly.
  • Check your water channel regularly to make sure that it's filled with salt water. At times, the pressure which builds up inside the crock can cause suction, which pulls the channel water into the crock (it happened to us a few days in). If this happens, pour more of the salt water into the channel to keep it full.
  • After the first 2 weeks, check your sauerkraut’s brine level and skim off any mold or bubbles that have gathered near the top. Be sure that your cabbage is always submerged in the brine. Fermentation breeds strange sounds and smells, so try not to worry about those. Close the fermentation crock again and refill the channel with salt water.
  • Your sauerkraut should be ready in about 4-6 weeks. You will know for sure once bubbles no longer appear in the liquid. The longer you allow the cabbage to ferment, the tangier the flavor will be. Check back on the blog in 4-6 weeks to see how our experiment turned out!

  1. I make it all the time…It looks absolutely unkosher when ready before cleaned and processed… But the final product is better than anything commercially produced.

    We add apple slices to ours, and we only use sea salt.

  2. One of my aunts threw out her dads least just before it was ready, thought it was bad…. all lasso cleaned the Packard with scouring powder and steel wool.

    I have a great piece already translated from Yiddish (I have the original Yiddish) into English, about how they used to prepare cabbage to be fermented to use through the next year, plus other things they included in the barrels with the cabbage, and the social scene of the women & girls doing it in each other’s homes in Lithuania but I don’t know how to send it to you for you to review.

    Once, and again, Tori, you bring back memories of me
    as a young child in the kitchen with my Bobcha preparing
    to make ‘kapusta’ and a very tasty ‘kapusniak’ or cabbage
    soup. Again, through your Web Site I renew my
    Polish Heritage.
    And, still, the renewing of my usage of my second language, ‘Polish’.
    Thank you, Tori.
    God Bless,

  5. This is interesting, I will try it out tomorrow.

    For your kind information we make fermented broad leaf mustard, mustard leaf. We call it GUNDRUK in our Nepali language. It is very popular item in Nepal. We just collect these and semi dry for 2-3 days under shade. then we cut them into smaller piece, rubbed for few minutes over a table, then wash in cold water and squeeze the remaining water by hand. Then we take clean earthen pot, locally made by a special kind of sticky soil, then put the material into it little by little, pressing is needed while putting into pot, we don’t use salt and any other ingredients. after filling the pot we place the lid, then put it
    sunny place during day, and take it to the room during night. After 5-7 days we open the lid and take smell, it has a peculiar type of sour smell, if that type of smell has not developed yet we put some warm water and keep it for another 2-3 days. Then we take out all material from the pot and spread above Black cloth about the size of bed sheet and let it dry in sun, If the drying can be done in solar dryer, that would be much better, after complete drying we store it in air tight container or thick gauze polythene bag. we can store it for whole year, until the next season.
    we can make soup out of it like any other soup. Also we can make Pickle from it, we can add a littlee of Gundruk in any other vegetable.

    Thank you very much

  6. Hi Tori…Has the sauerkraut fermented yet? Just curious on how it came out.

    I gave the link to this to someone I met in a work related class last week. It got me thinking of a discussion we had with my Dad many years ago. His mother (who was orginally from Romania) used to make sauerkraut and she had put black seeds in which we later found out was nigella seeds….sort of a black caraway. Have you heard of or used these before?

  7. You can eliminate the water if you do something a little differently in the processing. How I have done it for YEARS is… I shred a head, 2-3 tbsp of pickling salt (finer than kosher salt and gives the brine a better taste) and pound the cabbage until the juices release and you get a ‘sucking sound’ when you pull the pounding device up (I use a wooden thingy from my applesauce sieve – round, about 6 inches long and about 1.5 inches in diameter) then I add another head shredded, 2-3 tbsp of salt and pound… repeat this process until you are about 3/4ths of the way from the top of the crock you are using. just before you add your plate and weights, stick your arms down into the crock and ‘turn’ your pounded cabbage, then press down, add the plate and weights and cover with a bath towel. then the 4-6 weeks, skimming everything off the top every week til ready :)

    1. Sounds like the way we make it. We cover it with cabbage leaves a small plate then weigh it down with a big rock we save just for that, cover it with a towel, tie it up and wait!!

      I have a fermentation crock similar to this one that purchased a few years ago. followed the instructions that was very similar to Tracy’s and wined up making about 20 pints. everyone was great taste even today we are still eating. One thing I have heard so many tells of how to store by using caners. So I tried a different way of processing the jars. I used a vacuum sealing process and this is the second year going and every jar thus far is a success. every jar is firm and smells great. I am very satisfied with my results.

  8. Excellent - 5 starsExcellent - 5 starsExcellent - 5 starsExcellent - 5 starsExcellent - 5 stars
    I have the same crock.

    Wow…you didn’t “punch” the cabbage to get the proces started? That’s what I was told to do by the kraut expert that sold me the crock.

    Anyway, the kraut was amazing and crunchy. But then I heated it and canned it. Now it still tastes fine but it’s dark brown and mushy. I prefer the crunchy, fresh kraut right out of the crock.

    So my question is: How long can you leave it in the crock, without heating and preserving it?

    1. Hi Mitch– if you keep the kraut in the crock it will continue fermenting and become overly soft/strongly flavored. Once it gets to the point that you’re happy with the flavor and texture, I’d suggest pouring it into sterile bottles and refrigerating it. The sauerkraut will continue fermenting, but refrigeration will slow down the process quite a bit, allowing you more time to enjoy it before it loses the proper texture. It’s also possible that you processed it too long in the canning bath, which may be why it became soft/limp. For sauerkraut I would suggest boiling the can for 15 minutes.

  9. I make sauerkraut every summer in my grandmother’s #6 churn. I make it with just cabbage and salt, never used water, but pack the shredded cabbage down with a stick until the brine covers it. We leave it 9 days (or longer if you like) then heat it and pack it in sterilized jars and seal it. This is how my grandmother always made it and “store bought” kraut can’t even come close to homemade. My son is helping this year so he can carry on the “krauting” tradition.

  10. My mother still makes sauerkraut and we want to keep the tradition going. Your steps are similar to the ones she uses except mom uses a 10 gallon crock that that has been passed down through the generations (made by Uhl Pottery) enough to do about 35 heads of cabbages she raised in her garden. I was happy to learn sauerkraut has beneficial bacteria for the gut which we all know keeps us healthy. Hooray for old world solutions ( cheaper than buying probiotics in the drug store)

  11. I tried to make kraut for the first time 2 weeks ago from the cabbages from my garden. Organically grown, beautiful cabages. I used 1/2 green cabbage and 1/2 purple cabbage. In two weeks now, I see the scum on top and have removed it but I see no bubbles and it just smells moldy and theres blue mold in the insides of my food grade plastic bucket. The cabbage is all under the brine level and has been from day 1. Is it spoiled? Again, ive seen no bubbles.

    1. Hi JIl, if the brine has been thoroughly overtaken by mold it is time to start over. It is difficult to determine how bubbly the sauerkraut should be since I used a fermentation crock and could not see the inside at all times. Some white mold and strange smells are normal, but if it smells like it’s spoiled then it’s best to start over. Bad bacteria or spores may have gotten into your kraut, which will cause it to spoil rather than ferment. Every piece of of equipment must be clean and sterile before starting, and the brine must be at room temperature before adding it to the cabbage. Also, try not to keep it opened and exposed to the air for any longer than necessary– you can check it after the initial 2 week period, but only open it as long as you need to, no longer. Hope that helps!

  12. I’ve got a Harsch 10L fermentaton crock, and am on my 3rd batch of kraut this year. The first failed, only had enough cabbage to do 1/3 of the crock. Had some mold after 4 weeks and a foul smell, so I discarded the whole batch.
    The second one is a work in progress. Had some issues with the water in the airlok channel, which, kept “syphoning” into the crock and may have contaminated that batch. After 4 weeks, the liquid (in the crock) had overflowed into the airlok channel, the kraut smells ok, but there is no flavor and the product is very firm. I transferred the kraut to 1 gallon glass jars and placed in the refrigerator to, hopefully, continue the fermentation process.
    The third batch is in it’s first week, started “burping” within 24 hrs (1 burp about every 5 minutes), and am relocating the crock to a cooler location. All comments/advice is appreciated.

  13. the bag of water to seal sounds so much easier! I want to know though, has anyone substituted sour whey for sweet whey in the inoculation process? the sour whey from yogurt as opposed to the sweet whey from cheese making?

  14. On my fourth year of kraut fermenting. Ist year in an open crock, the last two in a 20 liter straight sided water seal crock of Polish manufacture. My first batch was excellent and every batch since has just gotten better. The water sealing crocks are definitely worth the extra cost as they eliminate the task of removing the fermentation scum that accumulates in an open crock.
    I just shred the cabbage, sprinkle in kosher or pickling salt as I add the layers of cabbage, mixing with a large spoon as I go and firmly tamping down the cabbage to help create the brine. I also cover the top of the shredded cabbage with whole leaves and the ceramic weights.. Your crock, utensils, and hands don’t need to be sterile just very clean, I don’t mean pretty clean, I mean very clean! That’s it, I can’t imagine anything more simple and once you taste naturally fermented sauerkraut you won’t be able to imagine eating anything else. I use it to make sauerkraut soup as part of a traditional Slovak Christmas Eve meal and one of my all time favorite dishes Choucroute Garni. After fermentation I store in the fridge in an airtight container and it lasts for months without losing it’s flavor or texture because it is still alive, just sleeping, not dead like canned food.
    Table salt has iodine and will not allow fermentation to begin, don’t use it. My theory on the fluctuating water level in the water seal channel is that it is due to changing atmospheric pressure, that your crock is acting somewhat like a barometer. When high pressure moves into your area it “pushes” the water down and into the crock and when low pressure is present it allows the water to expand and fill the channel to the rim and sometimes overflow. I could be completely full of beans too!

  15. I just checked my kraut at the 10-week mark. I was disappointed to realize I had totally forgotten to put whole leaves on top. There’s a fair amount of white mold, so I’m hoping when I remove it the kraut will be okay.

    1. Hi Mitch,
      It’s not absolutely necessary to cover your kraut with whole leaves although it does help to keep the underlying cabbage clean. 10 weeks seems like a long time to ferment your kraut, how did it turn out?

  16. Excellent - 5 starsExcellent - 5 starsExcellent - 5 starsExcellent - 5 starsExcellent - 5 stars
    I just canned my first batch of sauerkraut and am currently loading the second crock full to start fermenting. I keep reading about the wonderful probiotic benefits of fermenting and I am wondering if I destroy those good bacteria when I process (can and heat) my sauerkraut?

    1. Canning will take the living probiotics out of fermented food. Best to let the sauerkraut live in the refrigerator, where fermentation slows down and you can still enjoy the health benefits. I’ve been told it can last up to a year in the fridge.

  17. Hi! Awesome directions! How much cabbage (approximate number of heads) did you put into the crock? How much did it make?

    I’m getting ready to buy a crock and trying to choose btwn 5 and 10 liter.

    1. I used two large (and I mean large kraut cabbages, 16 and 14 pounds each) They filled my 20 liter crock about 2/3 full, it is too heavy to move so best to pack your crock where it is going to stay. For me that is in a corner of my kitchen. I find the gentle “burping” of the crock as the kraut ferments oddly soothing. Weird…

    1. Oh no Mitch! Sorry to hear that. It happens from time to time. You have to be so careful that all of your utensils and tools– the crock, your hands, everything that touches the cabbage– is very clean. If not, a small amount of bad bacteria can get in there and ruin the whole batch. Better luck next time!

  18. My mum used white large buckets.plate on top then a stone weight on top.left for 3 months cool dark place.water salt and cabbage.she just used to scoop scum off remove plate and that’s it..awesome cabbage!!

    Great blog and documentation of the process… correction though. You mentioned taking care so you don’t bruise the cabbage. This is wrong, you actually want to POUND the cabbage as flat as possible, as in STEP 3 of this tutorial:

    link to

    I made a wooden tool for this out of a piece of firewood, I call it a STOMPER and the process is kinda fun. I have made two batches now by this method, turned out great both times…wonderful flavor. I have since bought some large pickling crocks, but the first time I used a gallon clear glass cookie jar. It was a little small, but great to because I could see all the bubbles forming and traveling up as fermentation happened.

    1. Hi Dave, while we do pack down our cabbage, we don’t stomp it so hard that the cabbage is crushed or bruised. It’s especially important not to bruise the barrier layer of cabbage at the top of the crock, as it’s there for protection. We’ve had excellent results without “stomping,” however there are many different techniques out there. Obviously you should use what works best for you (and if that means stomping, go for it!). I love the idea of a glass cookie jar, it would be neat to see the fermentation bubbles gathering.

  20. I know this a few months past the time you made your Kraut
    I started my 1rst. Batch 3wks ago every thing is going ok
    Except the water in the top channel keeps disappearing
    Could it be evaporating or being drawn into the crock ? Any suggestions ?


    1. Hi Ken, if you read the recipe above you’ll see that we ran into this too:

      “Check your water channel regularly to make sure that it’s filled with salt water. At times, the pressure which builds up inside the crock can cause suction, which pulls the channel water into the crock (it happened to us a few days in). If this happens, pour more of the salt water into the channel to keep it full.”

      Hi Ken,
      You can call me crazy but I swear the fluctuations in the water channel are linked to barometric pressure. I too have experienced this same phenomena with very batch I have made, the past three years in a water sealing crock.
      During this years batch (which I just finished this past Sat. Yummy by the way!) I carefully monitored the water level in relation to the weather conditions and it remained stable for the first 4 weeks during which our weather was our normal autumn conditions of mild, cloudy and moist weather. We had a post-Thanksgiving cold spell here in the Pacific Northwest and we experienced a week of very dry, frigid and clear weather. Around here these wintertime conditions are always accompanied by very high atmospheric pressure and sure enough my water level began to fluctuate dramatically. The water would seem to disappear overnight but was actually being pushed into my crock and as soon as the conditions changed to our more normal wet mild weather, which is always accompanied by low pressure, the water channel began to fill again as it was (I believe) pushed out of the crock by the now higher pressure inside the container.
      So long as this stable weather system prevailed the water level remained unchanged. That’s my story and I’m sticking to it!

  21. Very good - 4 starsVery good - 4 starsVery good - 4 starsVery good - 4 starsVery good - 4 stars
    I just started my first batch. I followed the directions to a “T” but found that I actually had to put 12 cups of salted water to bring the level to 1.5 inches above the weights. After sitting for four hours there wasn’t much juice from the cabbage. I used fresh organic cabbage that looked great. I have a 3 gallon fermenting crock and I used 6 medium heads which filled it to a little more than halfway. Hoping for the best. Upon further reading I found that it can take up to 24 hours for the juices to release. Should have researched a little more…

  22. I bought a German crock and it’s HUGE!
    I used 3 heads of cabbage and 15 carrots. Added fennel and anise seeds.
    Question: Do you have to fill the crock to nearly the top or can it be half full of cabbage? The opening is too small to place a plate on the cabbage and then the stones so they went directly on the cabbage leaves.

    The liquid volume was 2 inches above the stones. I am concerned that the stones look odd…kind of irregular with what I’d guess is grease ground in?? Wonder if they are safe..been too long to contact seller I fear. Your thoughts?

    Anyway..I did not use salted water for the channel and I think my channel water got sucked in so I don’t know if it went dry or just disappeared… I checked it every 2-3 days.
    I am a bit sad my first attempt in my crock went sour..:-)
    I have made several batches in jars with off and on results.
    I wish I had the cute crock shown here!

    1. Hi Annette. The size of the crock shouldn’t make a difference, as long as everything is fully submerged in the brine, including the stones. It doesn’t “need” to be filled to the top. Ours wasn’t even close to full. Also, we didn’t place a plate between the cabbage and the stones, it isn’t necessary. As for the stones, I’m not sure what you mean when you say they are irregular, but they shouldn’t look greasy. It’s important that every single thing you use (crock, stones, any utensils, hands) has been thoroughly cleaned and sterilized before you begin.

      If the liquid appears to have dried up, you need to make more brine to refill the channel. When you say your are checking every 2-3 days, do you mean you are checking the channel or opening the crock? Checking the channel daily is a good idea, refill with salt water as necessary. However, you definitely should not be opening the crock every 2-3 days during the fermentation process. Every time you open the crock the sauerkraut is vulnerable to contaminants from the air, which can lead to spoilage. Hope that makes sense!

    2. Hi Annette,
      Cleanliness is everything when it comes to fermenting anything, be it beer, wine or cabbage! I put my crock weights in the dishwasher before and after use. After washing to remove any physical soil and contaminates, you may consider sanitizing them with hot water but be careful! Do not immerse the cold stones into scalding hot water, they may break. Warm them first with very warm water from the tap.

  23. Yahoo! Started my first batch in a 10 L gärtopf! 10 lbs of cabbage, salt, much pounding and a lot of love. See it in 4-6 :)
    Enjoying the guidance and suggestions here.

    Hi Tori. I just received my beautiful new crock; it is unpacked and set up on my counter. It is the same one you pictured here except I got the 10L having absolutely no clue as to what I am doing. Very excited about this new adventure! Your instructions and accompanying photos of the process are enormously helpful to neophyte! The crock did not come with any instructions for first use: do you wash these pottery crocks with SOAP and water? Do you use white vinegar to remove any last residue of soap that may remain after rinsing. The crock is large, heavy, bulky, and rather unweildly so not sure how to do this without chipping the crock. Then, how do you ‘sterilize’ it — I’m afraid of pouring boiling water in it for fear it might crack. I would imagine that cleaning it this first time should be done right before I’m about to use it to reduce possibility of ‘contaminents from air?’ What an utterly great blog this is!!!

    1. Hi Sandra! I know what you mean, it’s a very big and heavy crock. We were able to fit it into an otherwise empty dishwasher; we ran it through once to sterilize it, along with the lid and stones. Do you have a dishwasher? If not, good old soap and hot water will probably do the trick and your idea to follow up with vinegar sounds like a good one. I wouldn’t pour boiling water in or immerse the stones in boiling water either, you are correct that they might break this way. The cleaner you can get it before you start the better! Have fun fermenting. :)

  25. Hi Tori….I’m saving money to get this crock from your online store! Have you tried making kimchi before? Is this crock good for that as well?


    1. Hi Dave– awesome! You will love it. :) I do not make kimchi because it is one of the few things in this world my husband can’t stand (truffles are another one). However I don’t see why you couldn’t make kimchi in this crock as well!

  26. You don’t need anything fancy or pricey. I use a 5 gallon ceramic/enamel pot, you can find these…the one’s with the blue overlay and smallish white dots, at any store. I simply use a stainless steel pot lid that is just a bit smaller than the factory lid. I put same inside of the pot, along with a 5 pound weight atop that….this compresses the cabbage as it ferments.

    Simple. I get excellent results….and I haven’t spent one dollar on “special equipment”. I am partial, though, to my 5 pound weight. Its a circular whiteish rock, found along a New Mexico highway. About the same size as an average cabbage head…how appropriate.

    Good luck!!!

  27. I prepared the kraut a 1 1/2 weeks age (MLK day). I’ve got the 10 l crock on my kitchen counter where it is pretty warm. I have yet to notice any “fizzy, bubbling sound coming from the pot.” I have not opened not moved to a cooler place, yet. Should I do either?

    1. Hi Ethan, as it says in the instructions above: “If you don’t hear anything, don’t worry, it may just mean that the walls of your crock are too thick for sound to travel through. After fermentation has started, move the pot to a cool place, between 59 and 64 degrees, for the remaining fermentation time. If you don’t hear anything after 1 week, go ahead and move the crock to a cooler location without waiting for it to sound bubbly.”

  28. I just began ( for the first time ever) cabbage in a crock. the water level dropped down a bit below the top of the cabbage and I see some black mildew. do I need to throw out and start again?

    1. Hi Judy, there should never be black mildew in the fermentation crock, so I’m afraid you’ll need to start over. Next time make sure that the cabbage and the weights are completely submerged in the brine before you begin the fermentation process; you may want to add an inch or two of brine above so the level never drops below the top layer of cabbage.

    Wonderful! My first batch after 5 wks fermentation is fabulous. Now, I’d like to send a couple of jars to family (one to PA and one to Germany). I have not canned the kraut, as to not kill what I worked so hard to get, but any suggestions for mailing a 1/2 quart jar. I put a piece of cabbage leaf on top in the jar as a natural cover and I thought of quick canning, i.e. putting it in a water bath for a minute or two just to create a seal. What do you think? Will it keep for a week at variable temperatures? thx

    1. Hi Ethan, that’s a great question. I would be wary of sending anything uncanned… I’m not sure what to tell you here. Maybe another reader will have a suggestion.

  31. Tori please help! I have made it one 2 years ago and it was perfect, the last 3 attempts it immediately molded BADLY in out pantry which stays around 69 degrees. the only think ive done different is the first time i accidentally used too much salt, but it was perfect.

    1. Hi Rob, the best advice I can give is to keep all of your implements and the crock or jar you’re using very clean and sterile. Tips are shared throughout the comments. It’s also possible that you have some existing mold in your pantry that you might not know about. Mold spreads very quickly, so if there is already mold in that environment the fermentation crock can easily pick up the spores and allow them to multiply. Do you have another cool-ish area to keep the crock in?

  32. I always add a few TBSP of clear liquid (also strained through four layers of quality cheese cloth) from living yoghourt and some Braggs vinegar, both of which add extra probiotics to the mix. I think I found out about this from WestonPrice. I also break a capsule of very expensive probiotics into the mess, but do not know if this adds anything or even survives to spread its goodness.
    I add many items, hot fresh chillies, beet matchsticks, a few raisons, chopped figs I have soaked and washed to get ride of sulphates, sweet potato (both white and yellow), and lots of fresh pineapple. Finally, Junipers and other living seeds and spices I also add, and even bunches of herbs adorn my Kraut.
    Mine never looks as pretty as the ones I see on line. I want all the colours I can get into it as it seems such may help in health.
    My first batch cleared up irregularity problems within weeks and strangely, body odour disappeared. (sorry, but themes the facts)
    I sense my well being has improved and I really think the Kraut is the responsible addition to my Paleo diet. I have two meals a day and both have the addition of my Sauerkraut which sits in a smaller mason jar in my fridge.
    Namaste and care,

  33. Traditional sauerkraut is made with Juniper berries and cumin seed. Many mistake this with caraway seeds. The juniper berries are put in whole . My Moms made it this way all her life.

  34. started mine a few weeks ago, looks awesome. did about 25 pounds of cabbage and mixed in a few pounds of Brussels spouts between the layers. tried it today totally delicious also added caraway seeds

  35. Looking forward to a new kraut season here in the Northwest. The big basketball size cabbages should be available in about 3 weeks. Love all the great comments I have read on this blog and am thinking of going with some cranberries and cumin or maybe just stick with my traditional juniper berries and Brussels sprouts. Any suggestions?

  36. I tasted my sauerkraut today. I think it’s pretty darn good. First attempt for me. How do I store the finished sauerkraut ? Do I just leave it in the crock and take out small amounts at a time for eating? Or put it in jars in the fridge? I’m hoping to enjoy it throughout this winter.

  37. Why do you say not to press hard or don’t damage cabbage? My Grandfather started making sauerkraut when he was still living in Hungary. He used a 20 gallon crock and a wooden tamper to pound the cabbage as he added each layer. His sauerkraut was the best I think I’ve ever eaten. He always told me how important it was to break down the cabbage to release the water.

    1. Hi Doug, this is a note of texture preference. Tamping down causes a much softer end result, the leaves don’t hold their structure as well during the fermentation process. If you like the way it turned out when your grandfather made it, use his method…grandparents always know best, in my opinion!

  38. I live in Israel and I had this crock in my shopping cart at Williams-Sonoma on-line shop for quite a while, but the shippment was so expensive, that I kept postponing ordering it. And then we travelled to Poland for vacation and guess what – in the city of Boleslawec, in
    Lower Selesia (the border between Poland, Germany and Chech Republic) we came across a factory and the shop that actually produces these crocks! I was so excited! We shlepped one back to Israel and I went online to look for the receipt. And that’s how I came across your site. I assume your crock comes from the same origin :) (actually on WS site it say that it is made in Poland).
    So I did my first batch of the saurkraut following your receipt, and I have a couple of questions:
    1. After a couple of hours the level of the cabbage went down considerably and freed a lot of space. Can I add some cabbage before I finally ceal it?
    2. Shall I fill the crock with water up to the rim? Or is it just a couple of inches above the weights? But then there is still air inside…

    1. Hi Marina,
      As the cabbage ferments the resulting production of carbon dioxide will push the air out of the crock leaving a protective layer of CO2 over the cabbage thereby inhibiting spoilage. You don’t need to fill the crock entirely with brine, an inch or two over the the stones should be sufficient.

  39. Excellent - 5 starsExcellent - 5 starsExcellent - 5 starsExcellent - 5 starsExcellent - 5 stars
    I followed your recipe thoroughly and we are enjoying Wonderful! sauerkraut. The best. I just packed the crock for another round.
