The airlocks allow gas to escape as the yeast starts to ferment the apple cider in these five gallon pails. It prevents air (and other stuff) from getting into the cider. These batches of cider began bubbling 24 hours after I pitched the yeast. The cider is from Cider Hill Farm in Amesbury and Pine Hill Farm in Colrain.
