3 days ago i started my first home brew useing tooheys draught i seen a video on the net showing how to make a cheep fermenter useing a bucket hose and jar so i was of to the hardware and made my own fermenter i cut a hole in the lid for the hose airtight i ran the hose from the lid into a jar half filled of water im a bit worried because i heard that durring fermenting the water in the jar should make a bubbleing sound but mine just has heaps of little bubbles in the jar is that normal is something wrong ?
