I started brewing about a year ago and have always done partial mash brews from Ahs. I have had good luck hitting close to my og numbers, but the last brew I did came from a different place and the instructions called for a 90min mash vs my old 45min mash. It called for more sparge water instead of 1qt per 2lbs of grains . Well my OG ended up low , it called for an 1.054 og and I had a 1.046 og. Should I stick with my old method or does anyone have a good method that I should try.
