Placed above the carboy on a pierced stopper, this simple and solid bubbler is used in home breweries to protect the must in fermentation. It is essential for brewing beer because it traps and neutralizes toxic gases while allowing the pressure formed by CO2 to escape.

Operation: Filled with water, the bubbler acts as a siphon. The water insulates your home brew from the outside air. The bubbler thus prevents bacteria from penetrating inside while allowing the carbon dioxide formed during fermentation to escape from the demijohn.

 
Each of our brewing kits include a bubbler.
