Senior Airlock

Airlock for sealing your fermenting barrel. Slightly shorter than the bubbler airlock making it easier for small spaces and easier to clean.

Please note that your barrel will need an airlock grommet if you don’t already have one (sold separately).

An airlock is a device that allows air or gas to leave the fermenting vessel while preventing oxygen and bugs/debris or bacteria from entering the vessel.

There are different types of airlocks, however, the most common is a bubble airlock, which holds water inside it and as the gas escapes you can see bubbles or activity. Depending on how active the yeast is and the production of gas is, these bubbles will be more or less frequent. The water allows the gas to push itself out, but does not allow anything in.

Note: The airlock isn’t always the best way to determine the fermentation activity. So, if you find that it isn’t bubbling, it doesn’t mean that the beer isn’t fermenting. For more information on what to do if you don’t see bubbling,
