When used with whirlpool or dry hop additions, pure hop lupulin powder contributes to a concentrated flavor in your beer. Unfortunately, there is not yet a lupulin powder version of the Zappa Hop available, but I am sure it will be available in the future. Haas (Lupomax), Yakima Chief Hops (Cryo/LupuLn2), and Hopsteiner are the leaders in this field, so check the websites periodically.
