I'm going to begin using a 5 gallon glass carboy for the purpose of dry-hopping. I'm curious, is a 5 gallon carboy exactly five gallons when filled to the absolute brim, or is there maybe a quart or so of headroom?
I'd like to get as much of my brew into the carboy as possible, and generally do batches that tend toward 5.25 gallons. If I can't get it all in there, would putting the excess in a glass jug (with airlock) be an acceptable alternative, then recombine at bottling?
Back to brewing! It's been too long!!
