Manufactured using 304 grade stainless steel, the Kombucha FV 300L is a specialised version of our temperature-controlled fermentation tank. Initially, this fermenter was designed for use in a Kombucha brewery, where the main purpose is heating rather than cooling.

A regular beer yeast reacts with sugar to create alcohol and, from this, heat is given off which may spoil a beer if the level reaches above about 30°C. A Kombucha yeast, otherwise known as a Scoobie, doesn’t emit heat like this, and needs a temperature of 30°C to ferment correctly. This means that if conditions are cool it may be too difficult for the fermentation process to complete.

The system we developed is able to pass warm water through the stainless immersion panel in the fermenter, gradually raising the fermenting temperature. Delivering a gentle heat is important to ensure that the yeast cells aren’t killed; this would very likely occur if we used a heat source like that which is used in our boilers & hot liquor tanks.

The system is fully automatic and self-contained – no external input will be needed. In addition to this system being ideal for Kombucha or Kefir brewers, it has also been used successfully for other
industries where a gentle heat delivery is vital.
