Fermentation locks, filled with a suitable sealing fluid, have the purpose of protecting fermenting and fermented drinks and mashes against air ingress and thus the detrimental influence of atmospheric oxygen, micro-organisms which need oxygen, and dust and fruit flies, while at the same time allowing the carbon dioxide from fermentation to escape. Fermentation locks thus also allow for easy monitoring of the fermentation process.
The larger the fermentation or storage container, the larger the fermentation lock should be.
Violent fermentation and storage containers with plenty of headroom require larger compensation vessels.
Fermentation locks with a pulled out or angled shaft are intended for low clearance, e.g. low ceiling heights or groups of fermentation and storage containers stacked on top of each other.
