A demi john is one of those 5 gal bottltles with a ring on either side at the top- and we boiled up 10000 mushies as the pint an a half of hot water u use in makin the peach snaps made up to 5 gal with sugar n water n yeast- airlock on the top so it can breath- looks like mud after u strain the mush juice but in a few days it goes pink fook knows where the sediment goes but it it it goes - six weeks of brewin time and yer good to go- l dont think JD would work coz its gotta ferment but there are other mixes than peach snaps- have a mooch bud- l thought ld wasted 10k of mushies but it was crackin stuff- hope thats kinda clear mate but if u need out clearin up let me know - im a 50 year old mushie head and its always a pleasure to meet another!!!
