So I'm working on some cider, somewhat following a YouTube recipe (heavily modified.) I condensed two gallons of cider down to about 1.25 gallons, then added two cans of apple juice concentrate, a package of (boiled) baker's yeast and a pack of Mangrove Jack's M02 Cider Yeast. I put it all in my 6+ gallon BMB fermenter with the "universal" lid, one solid bung and one drilled. I keep having to force the lid back down because it keeps getting pushed up. Of course this causes the CO2 out through the airlock, so I have to refill that...
