Fermentation Airlocks

Airlocks enable CO2 to be released during fermentation, but it traps oxygen from entering the fermenter and harming your beer or wine. Northern Brewer offers fermentation airlocks for beer, wine, hard cider, and anything else fermentable! Choose between the Bubbler Airlock and the Three-Piece Airlock. Compatible with all our drilled stoppers.
