I'm trying to create a hop schedule using galaxy hops and wanted to use magnum as a buttering hop then use galaxy as flavor and aroma hops. I've used two calculators and they suggest that my ibu's will be 112. I've read that these calculators don't do very at calculating ibu's for late hop additions and was wondering if anyone knew the actual hop utilizations. I want to showcase the galaxy hops by using extensive amounts but I think 112 ibu's is a little much for 1.060 ipa. Should I just throw out the magnum 60 min addition and go with pure hop bursting?
