Kraut Source - Fermentation Made Simple

Just one more day to go! 
Our campaign ends on Tuesday, August 26, at 3 PM, PST.

Kraut Source is Mason jar kitchenware for making fermented foods like sauerkraut, natural pickles, kimchi, kefir, and more. It's stainless steel, dishwasher safe, and easy to use.

If you are already buying live-culture fermented foods, you know how expensive that can get. Kraut Source encourages the DIY, artisanal spirit by enabling home chefs to create gourmet fermented foods, economically.

Kraut Source is designed for singles and families of all sizes. It fits on wide-mouth Mason jars, so you can make pint, quart, or 2-quart size batches. It takes up little space, so you can have several batches going at the same time. Its elegant, streamlined design means that it will look really nifty on your counter top.

Naturally fermented foods like sauerkraut and pickles are gourmet superfoods. Whether you are following a raw, vegan, vegetarian, gluten-free, paleo, or somewhere-in-between diet, eating fermented foods on a daily basis is good for you because they contain probiotics, enzymes, and vitamins.

The Problem

We started fermenting the old-fashion way with a big crock and a rock to keep the vegetables submerged underneath the brine.  The "crock-n-rock" method was inconsistent, as some batches turned out good, and some spoiled.  The batches were so big that they could feed a whole village.  Then we also had to transfer them into many jars that cluttered up the fridge. Plus they were all the same flavor. Boring!

We wanted to make different varieties, try different spices, but it wasn't possible with the big crock. We also tried other methods ( such as filling a big plastic bag with water to keep the vegetables submerged, or using an airlock, or a jar within a jar) but there was no solution that was simple, elegant, and consistent.  That's why we created Kraut Source.

 The Solution

Successful lacto-fermentation requires 3 fundamental steps:

  • Carbon dioxide produced by the fermenting bacteria must be vented. If not vented, the container can actually explode.
  • Fresh air must be kept out because the health-promoting lactobacilli bacteria are anaerobic. Fresh air allows undesirable microbes to grow, tainting or ruining your ferment.
  • The vegetables must be kept completely submerged in the salt-water brine because exposed vegetables can rot.

Kraut Source beautifully fulfills these requirements:

  • Kraut Source uses a water moat to provide a one way seal that lets carbon dioxide escape.
  • The same water moat keeps new air from entering.
  • Kraut Source uses a compact spring press to push down and submerge the vegetables. The spring press works better than a weight (stone or glass hockey puck used in other fermentation systems) because the spring exerts several times more downward force.

Besides fulfilling the basic requirements, Kraut Source does more:

  • Convenient. It fits onto a wide-mouth mason jar, so when your fermentation is complete, just remove Kraut Source, attach a regular lid, and place in the fridge for storage.
  • Attractive. It has a sleek elegant design that looks good on your counter top.
  • Durable. It's made from heavy gauge stainless steel.
  • Food safe. Stainless steel and glass are two of the safest materials known.
  • Consistent. Produces batch after batch of gourmet quality fermented foods.

How it Works

Endless Variety

There are endless varieties of fermented foods.  Nearly every culture has invented their own favorites. (German:sauerkraut, Korean: kimchi, South American: curtido, India: chutneys). Kraut Source opens the door to variety and creativity.  Impress your guests with unique homemade gourmet fermented recipes that cannot be found in any store.

Please help us reach our goal

We spent almost 2 years designing and refining Kraut Source.  Our mission is to make it fun and easy for everyone to make healthy and delicious fermented foods at home. Please support us by pre-ordering through one of the pledge/reward levels and also share our Kickstarter page with your family and friends.

Risks and challenges

The designer's life has gotten a lot easier in the last few years with 3D CAD & 3D printing. We created several 3D printed versions, then looked for a manufacturer who could produce Kraut Source in stainless steel.
With help from a number of very generous advisers and financial supporters, we identified a manufacturer, then produced several steel versions that we tweaked until we were satisfied.
We've already produced a small production run of 100 units that we've sent out for testing and feedback.
One issue that we uncovered in our testing is that existing Mason jar rings can't stand up to the acidic brine solution. A goal of our project is to produce stainless steel rings. We'll either get our current manufacturer to produce them or find a company that already produces rings and get that supplier to run them in stainless steel.
