Fermentation Airlocks
Airlocks for fermentation let the gas created by the fermentation process out, while keeping air from reaching the wine. Bubble airlocks (also known as S airlocks) and Senior three piece airlocks are the most common styles. A drilled (bored) bung is needed to use the airlock in a carboy or jug, so check out our selection of Bungs and Stoppers.
