Hops are the name of the game with a double IPA, but we knew we had to take it one step further. With Hop Bullet, we're using a new technique, hitting the beer with a blast of magnum hops and lupulin dust - pure, concentrated hop flavor - directly into the tank to emphasize the intense pine and citrus flavors of classic West Coast hops. www.sierranevada.com.
