The Boss — waterless airlock for desert fermenting


I have a beautiful 5L fermenting crock I got as a wedding present (the brown one pictured above). It fits three shredded cabbages and makes the most beautiful, mold-free kraut. It does this by means of a water-filled moat around the top (similar design to a butter bell) that lets carbon dioxide out and doesn’t let oxygen in.

But I need more vessels. Right this moment I have a batch of kraut going, and it needs at least another month. I want to do some quick, small batches of veggies in the mean time.

My only complaint about the magnificent crock is that our dry air (~20% humidity) sucks the water out of the moat at a rate of more than 1 moat per day.

Enter the Boss Pickler, from Primal Kitchen of Olympia, WA. It’s a glass jar with a silicone gasket and a silicone nipple that serves as the airlock. Brilliant! (They also make Kraut Kaps for less than $10, if you’re less of a fanatic about avoiding plastic and don’t have the evaporation issues we have).

I bought a 2L and a 1.5L on Etsy. I can’t wait till to try them out.

Update: The pressure of fermentation seems to make my brine dry up in the Boss Picklers. My sister-in-law is doing a lot of experimenting and seems to think covering it with a cloth for the first week or so is the way to go. Anyone else care to weigh in?

  1. Any further update on your experience with the boss picklr? I’m in the desert myself right now and am looking for ferment again….the Boss Picklr intrigues me since it doesn’t take up as much space as a regular airlock, but I can’t seem to find much personal experience with it.

    1. Kathy,
      I do seem to lose water from the boss picklrs, but it’s hard to know if a 90+ degree trailer is really a fair environment to test fermentation hardware. I have a few weck jars that seem to work similarly to the boss picklrs, and they’re cheaper. Good luck.
