How Much Salt do I use for Sauerkraut?

Sauerkraut – Using The Correct Amount of Salt

Making sauerkraut for the first time can be intimidating. I promise you it doesn’t have to be. There are just a few things you need to get right for a tasty, full flavored kraut.
The first (and most important) question I always ask myself is how much salt do I use for sauerkraut?

Expert sauerkraut makers agree on one thing. The amount of salt is critical to the quality and safety of your sauerkraut. The correct amount of salt for any recipe is 2% percent of the weight of your cabbage. This assumes your cabbage is fermenting in an 18C to 21C environment. As you keep reading, you’ll learn how to quickly calculate this for yourself.

In a nutshell, the method goes like this:

  1. Weigh your cabbage
  2. Do some math
  3. Weigh your salt

Seems fairly straight forward doesn’t it?

Step by Step Salt and Cabbage Measurements

Step 1 – Weigh your cabbage

First, weigh your cabbage using a digital kitchen scale.

By the way, I’m intentionally using the metric measurement of grams for this. It’s just easier to work with than the imperial system.

TIP:
Don’t weigh your cabbage in the condition you’ve purchased it from the market.
Instead, weigh it after you’ve torn off the outer leaves and removed the tough inner core.
The trick is to weigh the exact amount of cabbage that will end up in your sauerkraut.

For our example let’s say you’ve set your cabbage on a kitchen scale and it weighs exactly 2000g. (about two heads of cabbage)

Great, step one is done!

Step 2 – Do Some Easy Math

So from step one,  you discovered your cabbage weighs 2000g right? For step two, take that number (2000g) and multiply by .02. Notice how the number “2” is in .02? That’s how you end up with 2% salt.

Wait, before we continue, a lot of our readers don’t like math! So why not try our sauerkraut calculator directly below?

Sauerkraut Calculator

Type the number of grams of cabbage you have below:

For ??? of cabbage, you will need ??? of salt.

Note: This will give you a 2% salt to cabbage ratio. Which is exactly what you want!

After you multiply, you’ll end up with the number 40. That means 40g of salt is needed for 2000g of raw cabbage.

Let’s look at that again:
2000g of cabbage multiplied by .02 equals “the number of grams of salt you need”

OR

2000g x .02 = salt
2000g x .02 = 40g of salt

This also works for any amount of cabbage!

Let’s change the amount of cabbage and see what happens.

If you have 200g of cabbage, it would look like this…
200g x .02 = 4g salt

What about 654g of cabbage?
Let’s do it.

654g x .02 = 13.08g salt (we’ll just say 13g even)

And just to make it sink in, let’s have a little fun.
What about 40,000g of cabbage!
No problem.

40,000g x .02 = 800g salt

Fantastic, step two is done.

Step 3 – Weigh your salt

Now, simply weigh your salt with a kitchen scale to match the answer you got above. That’s how much salt you should use. There are no tablespoons to measure here.

Next, find out why tablespoons are inaccurate when measuring salt for sauerkraut.

    your post is quite old, but it has been extremely useful when yesterday I prepared, for my first time ever, my first fermented sauerkraut! I have just read a book by Dr. Perlmutter who recommends fermented vegs.
    Thanks a lot from Rome (Italy)

      Hi Oriana,
      Congratulations on your first batch of sauerkraut! I think that’s great and happy I could help with that. Just curious, which book of Dr. Perlmutter did you just finish reading? Was it possibly “Brain Maker” by any chance?

    Thank you for the calculation. In lock-down here in Sydney, Australia, I’m about to make my second (well, really third) attempt at sauerkraut. The first I threw out – I didn’t have weights and I gave up (this was a year ago). I’ve since bought a crock (last June) and finally started using it last month. This attempt was fabulous – crunchy and delicious. I found your site today because I couldn’t remember the ratio (using grams) of salt to cabbage. And, I really appreciate the detail and I’ve downloaded the resources from the University of Wisconsin to review as well. I hope you’re staying safe and have access to healthcare if needed. kind regards, Gillian

      Hi Gillian,
      It’s great that you stuck with it and kept trying. I had a few discouraging batches when I first tried myself.
      So far so good here, still healthy:). Hopefully the curve starts to flatten for everyone soon.

    I am virgin in this field, and looking for the ratio of salt to cabbage, I am disabled and have a lot stuff going and I found Sauerkraut as lot of my meds do my gut in but okay to eat it as I check first with my consultant doctor.
    it has help a lot side affects of the meds and I feel more comfortable and it give a lift.
    My only problem is the cost of buying the product ready made, so wanted to look into making it myself; which would keep the cost down for me.
    I have looked at book on the subject but could find what ratio was for salt to cabbage; you have simply answered my question / query on that subject. So I give a big thank you.

      Hi Tony,
      It’s great you’ve found that sauerkraut helps you support your health.
      I personally know someone eating fermented foods during and following long term use of antibiotics, so I hear you.
      Making sauerkraut yourself will no doubt cut down the costs a lot.
      And you’re very welcome for helping you out with the salt ratio. I’m very happy you found it useful.
      I wish you the best of luck with your fermenting.

      Anton
