Getting ready to brew a dry stout. The recipe called for about 0.7 oz of target hops for 60 min (11% AA). These were unavailable at LHBS so owner suggested goldings as a replacement, but only at 3.7% AA. I plugged this into a hop conversion app and it calls for 2.1oz of the goldings as a replacement. If this is purely for bitterring purposes should it work out? I've never had to substitute hops before (this is only batch 8 or so for me). Open to any and all advice.
