AIR CAP DURING FERMENTATION D

• Large and efficient pipe for home production of wine, beer and the like
• The stopper protects against insects
• Special ventilation holes are designed inside the stopper
• Elastic, suitable for multiple uses
• Transparent and flexible, allows you to observe how it “works”.

The fermentation process uses an airlock filled with water to protect the contents of the batch from oxygen saturation, while at the same time allowing for regular emissions of carbon dioxide produced in the ongoing process.
A special protective plug prevents fruit flies from entering the container, while at the same time not affecting the fermentation process.
