I've read a bunch about 2.5 gallon brews and scaling the hops etc., but I am trying to figure out if the Boil Volume should scale as well.
For a 5 gallon brew your boil volume would be (about) 3 gallons or so, and then add the extra 2 to 2.5 gallons post boil to bring your batch volume to 5.
For a 2.5 gallon brew, do I need to scale this? Or can I simply just boil 3 gallons to bring it down to around 2.5 and no need to add water post boil?
Thanks for the help, noob here. Got the good ol' Caribou Slobber in the fermenter at the moment, and I want to start doing some single hopped IPA's to get a good feel for the taste of different hop varieties (and I don't wish to have to make two cases of beer each time...)
