Classic Sauerkraut

Classic Sauerkraut at 1840 FarmI enjoy the tangy flavor of sauerkraut paired with many dishes and also served on its own. For years, we have been purchasing a local kraut. Each time we served it at our family table, I wondered if we could make a homemade version.

The process of fermentation seemed a bit daunting. The recipes all made the technique seem so simple that I doubted it would be so easy. A few weeks ago, I finally decided to take the plunge and try it for myself.

As I searched for a foolproof recipe and advice to ensure success, I discovered Kraut Source’s blog and innovative lid system. They were kind enough to lead me through the process of making our first batch of kraut step by step. They shared their recipe for classic sauerkraut which I adapted further to include only three ingredients: green cabbage, sea salt, and filtered water.

After a week’s time on the kitchen counter, the humble shredded cabbage my daughter and I had packed so tightly into the Mason jar had been transformed into a delicious, tangy sauerkraut. I was equally amazed at how simple it had been to make and how amazingly flavorful it was. It was so delicious that weKrautSource made a second batch, doubling the recipe to ensure that we never run out of this delicious, homemade classic sauerkraut.

With gardening season fast approaching, we’ll be planting a few heirloom cabbage varieties so that we can make our own kraut using cabbage fresh from our organic garden. We hope that you’ll join in and try your hand at fermenting a batch of sauerkraut using the classic recipe adapted from Kraut Source below.

Visit Kraut Source’s blog, Facebook page, and Instagram feed to learn more about the art of creating cultured and fermented foods in your kitchen. They fill my newsfeed with a steady stream of delicious recipes and helpful tips. I know that you’ll enjoy following them as much as I do!

Shredded Cabbage for Sauerkraut

Lacto-fermentation takes advantage of the beneficial bacteria (including Lactobacillus) that are naturally present on the surface of fruits and vegetables including the cabbage called for in this recipe. When held at room temperature and submerged in brine, these healthy bacteria convert the natural sugars in the cabbage into lactic acid. The lactic acid will naturally preserve the kraut and inhibit the growth of harmful bacteria.

Much like canning, fermentation requires clean tools and surfaces to safeguard against potentially unsafe bacteria. Simply washing all the tools and equipment and your hands with soap and hot water before beginning the recipe is sufficient. This will ensure that you have begun the process with the clean environment necessary for successful and safe fermentation.

1 1/2 pounds (675 g) green cabbage
1 Tablespoon (15 ml) sea salt
brine as needed (1 teaspoon sea salt dissolved in 1 cup cold, filtered water)

Quart-size Mason jar
Kraut Source Unit or Mason Jar Lid

Rinse the head of cabbage in cold water. Quarter the cabbage, removing the core before finely shredding each quarter. Place shredded cabbage in a large bowl. Add the sea salt, tossing to evenly distribute. Allow the cabbage and salt to rest for 10 minutes.

Massage the sea salt vigorously into the cabbage for about 5 to 10 minutes. Working the sea salt with the shredded cabbage will help to draw liquid out of the cabbage and begin the process of breaking down the fibrous nature of the cabbage.

Packing SauerkrautIf you have time, allow the massaged cabbage to rest in the bowl as the salt will draw out liquid. If you do not have time to wait, simply pack the cabbage into a quart-size, wide mouth Mason jar. Use a pounder or wooden spoon to really press down and pack the cabbage in . The top of the cabbage should be even to the shoulder of the jar. If there isn’t enough liquid to cover the cabbage by one inch, add enough brine to cover.

Secure your Kraut Source unit or lid on the jar. Take care not to tighten the lid too tightly. As the cabbage ferments, carbon dioxide will be released. If the carbon dioxide is not allowed to safely escape the jar, it can cause the jar to break or the lid to be forced off of the jar.

The innovative Kraut Source unit contains a spring and a press to hold the cabbage underneath the surface of the liquid while allowing the carbon dioxide to escape. If you are using a standard lid, a piece of the cabbage’s core or a small weight can be used to keep the sliced cabbage below the liquid .

The lid can be removed every few days and replaced to adequately vent the excess carbon dioxide. During fermentation, the cabbage must be completely submerged in the liquid to prevent spoilage. Additional brine can be added as needed to completely cover the submerged cabbage.

Allow the kraut to ferment at room temperature for 5-7 days or several weeks to develop the desired flavor. After 5 days, begin tasting the kraut every few days to determine if the flavor is to your liking. When the taste is agreeable, transfer the kraut to the refrigerator. Any weight or cabbage core used to keep the kraut submerged can be removed at this point.

We find ourselves enjoying this homemade sauerkraut on top of nearly every sandwich or alongside most main courses.  We love to enjoy a side of it with our Beer and Brown Sugar Braised Pork Roast and Cast Iron Skillet Pork and Potato Hash.



  1. I’m going to try this and the kimchi recipes. They sound wonderful & this will be my first attempt at fermenting. I’m just wondering how long the sauerkraut stays safe to eat once in the fridge?

    1. Also, I don’t have filtered water. Just well water, but it’s great water. Should I boil it or something?? Sorry for the dumb questions lol!

        No need to apologize! I’ve asked every question before and am happy to answer any questions that I can. Filtered water is best and is the only type of water I have ever used when making fermented recipes. Both of these recipes require very little water, especially if you allow the cabbage to sit with the salt a little longer and work it enough with your hands to create enough brine to cover the cabbage when it is packed into jars. Many times, I don’t need to add any additional brine, or a few Tablespoons at the most. Give it a try and let me know how it works for you!

      I am so glad that you are going to give them both a try! Opinions vary on length of storage for sauerkraut, but 6 months is a good place to start. Many people store their kraut in a cool, dark place for a year or more, but mine never lasts that long!
