Bubbler airlock for use in demijohns and brewing bins

An old favourite, the bubbler airlock is ideal for beer and winemaking. Air locks prevent air getting into your brewing vessel and spoiling the must/wort, and allow the escape of the carbon dioxide (CO2) built up during primary fermentation.

 

Add a small amount of sterilising solution or cooled boiled water and place in a bored cork/bung or a grommet and use to seal a brewing bin, demi-john or wide necked fermentation vessel.

 

Air locks can be also be used in place of solid bungs  to seal demi-johns or fermenting vessels for long term storage.

 

Please note: The bubbler DOES NOT come with a bored bung.
