The Homemade Sauerkraut Project – It’s a Success! (Seriously, that Kraut is amazing!)

Ever since I did my first Whole30® a little over 6 months ago, I’ve heard so many great things about sauerkraut that I felt I really needed to incorporate it into my regular diet.

As luck would have it, I happen to love sauerkraut.

Not quite so lucky, though, was the realization that good sauerkraut is very hard to come across. And very expensive, too!

Most of the commercial stuff that’s available at the grocery store is loaded with all sorts of nasties, and more often than not, commercial sauerkraut is generally pasteurized and then packaged in a brine of extremely salty water. This kind of sauerkraut has none of the beneficial probiotics or enzymes of homemade sauerkraut.

There was only one thing left to do: I had to learn how to make my own.

So I read, and read, and read some more on the subject, until finally, I felt ready and comfortable enough to start my very first batch.

Of course, I took notes and pictures to share my experience with you.

Here’s how it went.

First, I went out and bought me what’s known as a Primary Fermenter. You know, one of those buckets that’s used to brew wine and/or beer at home.

Only I would put mine to much better use!

This beautiful food grade, 6 gallon bucket released my wallet of $40.

Not bad, considering all the batches of sauerkraut it’ll hold and ferment for me in its lifetime.

While I was at the Home Brewers Supply store, I also got me what’s called an Airlock, or Fermentation Lock.

This neat little contraption allows carbon dioxide to escape the fermenter but won’t allow air to get in, which prevents oxidation, or rot.

This nifty little gadget cost me an extra $5. Worth every single penny, if you ask me!

Now for the “ahem” handy and technical part…

Don’t worry guys, installing the Fermentation Lock will require only a few tools and very little “construction” skills.

First off, you’ll need a power drill and a hole saw of the appropriate size.

Your airlock will have to sit tightly in the hole that you will be punching with that saw, so pick a size that’s somewhere halfway between the larger and the smaller end of the airlock’s rubber plug.

You will also need some kind of a punch to mark the spot where you want to drill the hole for your airlock to rest.

Now that hole doesn’t HAVE to be smack in the center of the bucket’s cover. It could be anywhere, really.

I just thought dead center would be easier, and prettier!

Once that hole has been punched, you want to go ahead and pierce a bigger hole using the hole saw.

And place your airlock right in your freshly made hole.

Euhm… you might want to rinse it off first, to get rid of all those little pieces of plastic!

I was just demonstrating here that, TADA, it fits perfectly.

Now that you have your container taken care of, you will need to prep you some cabbage to put in it.

A lot of cabbage!

I used a total of 4 large heads plus half a tiny little one, just because it was begging to be part of the project, too!

So I gave in and let him join the others…

Homemade Sauerkraut Project | by Sonia! The Healthy Foodie

First, you will want to remove all the outer leaves. Then, cut your cabbage in 4 pieces and remove the core.

Now, you’ll need to finely shred your cabbage.

To get the job done, you could simply use a knife, but that would take you a while, and might leave you with a few blisters on your fingers…

Homemade Sauerkraut Project | by Sonia! The Healthy Foodie

A mandolin sure would be a nice upgrade…

But still, it would take you a wee while!

Homemade Sauerkraut Project | by Sonia! The Healthy Foodie

When I’m dealing with that big a job, I always like to rely on my trusty heavy duty food processor.

Equipped with the slicing disk attachment, it took care of the task at hand in no time at all!

Homemade Sauerkraut Project | by Sonia! The Healthy Foodie

And it shredded my cabbage to just the right consistency, too!

Each bowlful got thrown right into the big white bucket, until it was almost full.

I told you, we’re talking A LOT of cabbage!

Homemade Sauerkraut Project | by Sonia! The Healthy Foodie

Alright, time to add the salt.

For 4 large heads of cabbage like that, I needed 6 tablespoons of salt diluted in 4 cups of boiled (or bottled) water.

Homemade Sauerkraut Project | by Sonia! The Healthy Foodie

Also too, to be on the safe side, as well as to make sure my sauerkraut would be nice and crunchy, I chose to add some starter culture.

While not absolutely necessary, using starter culture pretty much insures you that nothing will go wrong during the fermentation process, as it supplies a great deal of bacteria to support the process right from the start.

So in went 2 packages of Caldwell’s Starter Culture diluted in 2 cups of bottled water.

Homemade Sauerkraut Project | by Sonia! The Healthy Foodie

Time to beat that cabbage up a little!

Or a lot…

Pictured above is what my cabbage looked like right after I added the salt and starter culture.

Homemade Sauerkraut Project | by Sonia! The Healthy Foodie

And that’s what I had after about 10 minutes of kneading, mixing, beating and mistreating my cabbage.

To get this job done, you want to whip up the heavy (and CLEAN) artillery, such as a meat mallet, a rolling pin (the French kind that has no handles, you know) or even a (brand new) wooden baseball bat, why not?

But I honestly think that the best tool for this is your hands. Make sure you clean them nice and good before you begin, and really go ahead and scrub all the way to your elbows. Because yeah, you’ll be digging this deep!

Now what you want to do is squish and squeeze the cabbage so that it releases some of its liquid, which will blend with the salt and starter culture to form your brine.

Eventually, the cabbage will have released enough water for the brine to completely submerge it.

Homemade Sauerkraut Project | by Sonia! The Healthy Foodie

At this point, you can stop beating your cabbage and wash your hands again. Trust me, you’re gonna want to.

Now, it is absolutely imperative that your cabbage stays submerged AT ALL TIMES during the fermentation process, so you want to help it stay under the brine.

The best way to do that is to push it down with a plate that fits nice and snug in your bucket and to hold that plate down with a weight.

I used water bottles, so I wouldn’t run the risk of breaking my precious plate! (yeah, I used one of my favorite ceramic plates… I like to live dangerously!)

Homemade Sauerkraut Project | by Sonia! The Healthy Foodie

Now that your cabbage is sitting safely and comfortably under that brine, you’ll want to put the cover on and add a little bit of booze (vodka is best) to your airlock.

Add just enough so it fills up about halfway on both sides.

You could also use water, but it’s better to use alcohol to prevent contamination in the event that some of the liquid would inadvertently be drawn into the fermenter.

Now put that baby away in a relatively cool room and leave it undisturbed for a full month.

Yeah, you heard me right. A FULL MONTH! That’s how long it takes for the fermentation process to complete.

Of course, you can check in from time to time just to make sure that everything is fine and that your cabbage is still under the anaerobic safety of the brine.

After a month, remove the lid and this is what you see.

Strange and very unappealing color, I know…

But don’t be put off by it. This is seriously good stuff, I guarantee it.

Let’s remove that plate and see what’s underneath.

Homemade Sauerkraut Project | by Sonia! The Healthy Foodie

Better, isn’t it?

Sure starting to look like sauerkraut to me!

Let’s pick up a sample and look at it closely.

Homemade Sauerkraut Project | by Sonia! The Healthy Foodie

Oh yeah! Beautiful

That’s exactly what I’d been hoping for.

Crispy, crunchy, super tangy and salty sauerkraut.

It’s perfect, in every possible way.

And I created that!

Homemade Sauerkraut Project | by Sonia! The Healthy Foodie

Time to transfer it into jars and place it in the fridge, where my precious kraut will keep for months.

Not only will it keep, it will also get better. Apparently, it takes about 6 months for sauerkraut to get to taste its very best.

Not sure it’ll last that long…

Homemade Sauerkraut | by Sonia! The Healthy Foodie

Oh, and by all means, do not chuck that leftover brine: use it to start a new batch, or even to try your hand at fermenting some other veggies.

I’ve only just started experimenting with this, but I get the feeling I’ll be fermenting ALL SORTS of things.

Of course, I already have another batch of Kraut going…

As well as a batch of fish sauce…

And some corned beef too!

Corned beef and sauerkraut. Now that’s a winning combination to me! :)

Homemade Sauerkraut | by Sonia! The Healthy Foodie


I’m aslo starting to think that soon, very soon, I’ll be tackling Kombucha.

Because hey, I’ll need something to drink with that corned beef and kraut, won’t I?

Ha! It’ll be the ultimate fermented meal!

    Nice! I am going to have to try my hand at sauerkraut – I have only ever made it in small batches before.
    I do have some kombucha on the go at the moment though.

  2. says

    Ok, this is BADASS! It’s like HomeDepot meets Julia Childs meets Chemistry Set.
    Some friends of mine have tried their hands at making sauerkraut, but failed miserably. It was like an eruption of mold or something. Really gross.
    So hats off to you Sonia; what you did is remarkable!

  3. Bonnie says

    Love, love sauerkraut, especially on mashed potatoes. Unfortunately, Hubby does not. I will have to find neighbors to share before attempting this. Please share the corned beef fermentation process and recipe. Thank you for sharing this sauerkraut recipe. :)

    • says

      Oh, but sauerkraut keeps for a very long time, Bonnie. And you can have a little bit every day, too! I made this whole batch just for myself, although my son is finding it really good and steals some frome time to time… who knows, maybe hubby will learn to love it too! 😉

      As for the corned beef, it’ll be a few weeks still before I know whether the experiment was successful. Fingers crossed! :)

  4. Susan says

    How great to have some good instructions on how to do this. My husband and I both enjoy good sauerkraut. We might take exception about your bucket being better for sauerkraut than brewing beer (although we would not brew our own beer) because we are huge fans of craft beer. And good wine. :-) Thank you for posting this.

  5. says

    Looks great! it has been awhile since I made sauerkraut. My better half already has a ton of home brewing supplies so I may think of making a batch or two this year. If I do I’ll try your method. Thanks for posting! ~sue

  6. Chelsea F says

    That is awesome! Is there a way to make it in smaller batches? Living in a small 1 bedroom apartment here…I do make my own kombucha though! It’s very easy. I make about a gallon a week (unless I forget about it and let it ferment longer…)

    • says

      Of course you can make a smaller batch, Chelsea. You only need get your hands on a smaller primary, or food grade bucket of some kind. The rest of the process is exactly the same! :)

      I can’t wait to start brewing my own kombucha. I feel it’s only a matter of a few weeks. I’ll know who to go to if I have questions! 😉

  7. Chris C says

    Bought the equipment, and now going to make the sauerkraut.I was wondering, have you tried to ferment other foods besides the sauerkraut. Wonder if you could make Kim chi, or pickles,using this set up?

  8. says

    Love your writing style, entertaining and informative. My family is starting to scale up our sauerkraut business in Minnesota and we are looking into holding classes to teach people to make their own kraut and other fermented goodness. It really is an incredibly simple and intensely beneficial process so thank you for helping to spread the wealth!

  9. James says

    Looks great, but FWIW Lowe’s carries food grade buckets for around $4, plus another $3 for a lid (Or $7 for a “Gamma” screw-top lid)

  10. Michelle Perry says

    I have a question. What if you don’t have the little airlock gadget. How would you do it then? Would I put the lid on the bucket?
