With two taps at home, one always has an IPA flowing. I started brewing not long ago and have brewed maybe 10 different Smash IPAs with different hops to judge which hop characters I like and don't like. I'm now going to try different grain bills and was wondering everyone's opinion. Do you have different grain bills for all of your IPAs? Or once you settle on a solid grain bill do you just stick to that and sub hop combos? I have made 2 good IPAs with the same base recipe including Maris, C40, and aromatic malt which got me wondering if I should just stick with that base recipe for consistency? Thanks!
