I need help with a hop substitute. The recipe I'm looking at calls for 1 oz of Hallertau Hersbrucker at 60 min (of a 60 min boil). Being pretty new to brewing, I'm still trying to figure out when/how to substitute hops. I'm assuming that because these are added at 60 min., they're strictly for bittering purposes, right? With that said, how would I know what hops that I currently have would substitute correctly for the Hallertau? I currently have Mt. Hood, Willamette, Cascade, Simcoe, EK Goldings, and Chinook.
Any help would be appreciated.
