Is Dr. Rudi Available in Cryo/Lupulin Powder Form?
Unfortunately, there is no lupulin powder version of the Dr. Rudi hop. Neither Yakima Chief Hops (Cryo/LupuLN2) nor Haas (Lupomax) have created versions of this hop in lupulin powder form yet. This new type of hop product is pure concentrated lupulin powder, which leads to more flavor when used in the whirlpool or dry hop additions.
