I'm brewing an IIPA with a recipe I designed from beer smith. I know some higher gravity beers have a longer boil time. BeerSmith has my recipe boiling for 60 minutes, but should I boil for 90 minutes. I'm using nearly a pound of hops all totaled(including dry hopping), I use a partial boil, and late extract addition. My target OG is 1.090, and I have done a starter batch of yeast.
