So I'm 6 brews in (4 all grain) now and have figured out a bunch of my mistakes, but the US vs UK gallon thing still confuses me no end.
Carboys are 6 US gallon, 5 Imperial, and I know that most recipes list in US gallons, but why is it that a lot of recipes don't use the full volume of the carboy/primary? I thought it was bad to leave a lot of airspace over the beer, or is that a misconception too?
