i have yet to do an all grain, but this recipe looks right up my kind of beer!
that said, is this recipe do-able extract version? also, if doing a 5 gallon batch, i'm going to be cutting everything by half. is that true for the hops as well? final question, and i hope this doesn't sound stupid, but do you need to do a 90 min boil if 1st hop addition is at 60?
