Airlock and plug for Speidel fermentation tanks

The airlock filled with some water acts as a siphon. The water closes the beverage that is inside of the tank from outside air and therefore prevents the bacteria from the environment getting into the beverage. The lock enables carbon dioxide to be emitted during the fermentation process thanks to the overpressure that is generated during fermenting.

The water inside of the airlock evaporates over time, so it is necessary to check the water lever regularly and add water if necessary.
