As well as adding strength, the concave bottom also allows spent yeast to settle out after fermentation. The graduations make measuring a piece of cake. And the revolutionary Big Mouth makes cleaning easy by allowing you to get straight to stuck-on yeast deposits, and offers total control over flavouring additives and dry-hopping.


*The new Big Mouth Universal Lid included in the kit fits all Big Mouth Bubbler® Fermenters.


The Big Mouth Bubbler® Universal Lid is exactly like a standard demijohn stopper, only bigger! ...and it's just as easy to clean and sanitise, and fitting is easy too. The ridged silicone seals ensure pests are refused entry, while the unthreaded design lets the lid move, preventing run-away fermentation from over-pressurising the fermenter.


The optional Dual Port Lid allows you to use a thermostat sensor. Ensure precise fermentation temperatures every time with the ThermoStar Dual-Mode Digital Temperature Controller thermostat.


The lid port works with either a standard 6.5 rubber bung or the Northern brewer Small Universal Stopper.
