Can I make Kombucha in the Pickl-It?

In short: no.

Kombucha creates primarily glyconic acid. It likes air, so the Pickl-It wouldn’t be a good choice because the Pickl-It is designed for anaerobic fermentation – a type of fermentation that does NOT like oxygen.

Kombucha, on the other hand, LOVES oxygen. It needs to have oxygen floating across the top of its brine. A light cover of butter-cloth or loose-weave muslin is ideal for covering your fermenting kombucha.

Review:
Kombucha = glyconic acid = needs oxygen
Vinegar = acetic acid = needs oxygen
Fermented foods (kraut, pickles, sourdough, kefir) = lactic acid and does NOT need oxygen
