Joenos Fermentation Stopper 10 mm for Airlocks, 1 Piece

The fermentation stopper connects your airlock tightly to the fermentation vessel. The 10 mm version fits plastic and glass airlocks and ensures that fermentation carbon dioxide only escapes through the airlock, while no air gets into the batch.

A tight fit is crucial during fermentation: leaky spots let oxygen and fruit flies reach the wine and make monitoring the bubbling unreliable. A spare stopper therefore belongs in every cellar kit, precisely because these small parts tend to get lost or become brittle over time. 1 piece is supplied.
