I'm going to brew a 100% Golden Promise IIPA this weekend.
I'm not adding any specialty grains. I'm shooting for an OG around 1.070. I'm actually going to try a SMASH IIPA with GP and Glacier hops.
I like a drier IIPA, so I think an all base malt IIPA at that OG level should be about right. I think the worst thing you can do with an IIPA is make it cloying.
