This is a fermentation without foreign bacteria and oxygen!

The fermentation tube prevents during the fermentation process that especially oxygen and air enters the fermentation vessel. The resulting carbon dioxide can still escape. This prevents the wort from being contaminated by foreign bacteria, which could cause faulty fermentation, or oxidized to vinegar by the oxygen in the air.

A sealing rubber is needed to insert the fermentation bung in a lid of a PVC bucket or in a lid of a fermentation barrel.
