G'day brewers, I've got a head-scratcher here. I do all-grain BIAB and I've noticed ever since bulk priming with dextrose (using the calc on this site) all my brews are on the flat side. Some background on how I roll: I mostly do pale ales, wheat beers, stouts My recipes are scaled to 15 L each time I hit (or close to) my gravity readings I ferment and carbonate in temp controlled fridge for 14 days each I rack 14 L into a bottling bucket each time (1 L loss to crud etc) When I bulk prime I use the BF calc and input these numbers: Units: Metric Amount being packaged: 14 L Volumes of CO2: I'd go 3 or 4 (but there's no diff in the carb level) Temp of beer: Whatever I fermented at. I then weight out the corn sugar (dextrose) value it returns i.e. 180 gm, add it to a pot and cover with just enough water then boil for a minute or 2. I pour into bottling bucket then rack my 14 L wort and bottle from that point. I recently ditched my air lock and use glad wrap, probably not the cause but worth noting. I've had brews that were still flat 6 weeks after bottling. Any advice appreciated!!
