Sale price
Tax included.

Home fermentation can be difficult with the natural fluctuating temperatures. This flask has a double-wall vacuum that holds whatever temperature your ferment needs for extended periods, no need for electricity!

Included is a heavy glass AGEE jar similar to a Ball or Mason jar in size and shape -  with a stainless lid because we like making food in glass, not plastic and you can pop it straight in the fridge.

The Fermenting Flask is excellent for yoghurt, soft cheeses, cultured butter, kefir, dairy-free yoghurts. The simple, compact design makes it easy to clean and store.
