HBC 438 is an experimental hop variety originating from the open pollination of YCR 123, a cultivar derived from the subspecies neomexicanus. It is the sister to the well-known experimental HBC 472 and exhibits many of the same characteristics including a unique coconut aroma. HBC 438 imparts a strong and complex fruit flavor to beer. In a Haas Experimental Brewery brew dry hopped at 2.0 lbs per barrel, the beer aroma was described as mango, coconut, grapefruit, lemon grass, and wood. HBC 438 has shown to brew consistently, delivering its distinct and recognizable flavor every time.
