High Quality Bubbler Airlock for Wine and Beer Making
Simply add water to your Airlock by half filling and view bubbles as your beer or wine is fermenting.
An airlock is a device used by nearly all wine makers and some beer makes. Its purpose is to allow gases released from the fermentation to escape while preventing oxygen from the atmosphere from entering the container and potentially spoiling the wine / beer. It is essentially a one way valve.
