The Karl Kombucha Silicone Fermentation Lid & Air Lock is specially designed to be used with a Karl Kombucha 4 litre Jar. The lid is made from premium silicone and combines an Airlock which in turn creates an anaerobic atmosphere that is perfect for fermenting foods and creating alcohol Kombucha aka Hard Kombucha!
The airlock allows gases to be released from the fermenting foods or during the making of Hard Kombucha but does not allow air to enter the jar. Air entering the jar from outside can cause the food to spoil or stop the making of alcohol in your Kombucha.
Adding the fermentation lid to a Karl Kombucha Jar means that you can make Hard Kombucha
