A winter warmer. Almost a porter but still just about in IPA territory. I'm aiming for lots of body with maltiness balanced out with English hops. My supervisor in the photo is Stinky.
For most brewing salts, hot water works best to dissolve them. Gypsum specifically works the other way around, where it dissolves best in cold water (retrograde solubility). I always used to just throw the gypsum in before I started heating my strike water, and any other salts after it was hot but before grain.
