Airlocks & Stoppers

One of the most important aspects in beer fermentation is the evacuation of CO2 produced by the yeast from the fermenter. It’s crucial that during this process the gas to be evacuated from the vessel without getting any air, which may carry contaminants, into the fermenter. This is achieved by using a tight fit stopper and a dedicated airlock, and this category features all the things you’ll need to provide your fermentation vessel with an optimal airlock option.

Airlocks are quite simple in essence, as they’re based on the concept of water barrier, which lets the gases pass from within the vessel, where the pressure is higher during fermentation, while preventing the air from getting inside. There are different models made out of different materials, so you will have various options to choose from. And to make sure that the airlock has the perfect fit with the fermenter opening, we also carry a broad selection of rubber, plastic, and silicone stoppers and bungs of various sizes that fit the majority of conventional fermentation vessels.
