Fermentation Bubbler Airlock & Bored Rubber Bung by Almost Off Grid.
When you’re making wine or beer in a demijohn, you need a fermentation bubbler airlock and bored rubber bung.
It lets CO2 out of your home brew without letting contamination in.
Simply half fill the bubbler with water and you’re good to go.
The Fermentation Airlock is a standard size, so fits all fermenters.
The Rubber Bung has a bore hole in it for the bubbler, and fits Standard Glass Demijohns. (Looking for a cork bung instead?)
