Home fermentation can be difficult with the natural fluctuating temperatures. This stainless steel Fermenting Flask has a double-wall vacuum that holds whatever temperature your ferment needs for extended periods. Included is a heavy glass AGEE jar 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.
