Imperial IPA – All Grain

Statistics

General Info

Buddy Brew with Danielle Robinson. Double IPA brewed with seven "C" hops. Inspired by Dry Dock Brewing Company's beer of the (formerly) same name.

Comments

Substituted Calypso hops for Crystal.

Compared with the inspirational brew when at five weeks of age. Original was "smoother" - mine had a stronger bitterness bite to it; possibly a combination of fusel alcohols and minerals in the water. Original had more hop aroma and a lighter color. Aside from these three differences, all who sampled (five people), said this was "very close" to the inspirational beer.
