Yakima Cluster Hops

Dual: Aroma and BitteringAlpha 4.4 - 9.8%United States

Refined in the 1950s by the Prosser Research Center and tracked under the official designation USDA 65102, Yakima Cluster is a specific clonal selection of the oldest and most impactful hop lineage in United States history. While often indistinguishable from its genetic sibling Early Cluster and typically referred to simply as "Cluster," this specific variant was carefully isolated and engineered to thrive in the sun-drenched, irrigated soils of Washington’s Yakima Valley. This specific terroir is so vital to the plant's performance that the clone notoriously struggles to replicate its high-yielding agronomic success when grown in the more humid microclimates of Idaho or Oregon's Willamette Valley. Standing as a literal living artifact of the domestic craft movement, Yakima Cluster represents the missing link between the wild bines of the early American frontier and the precision of modern agricultural science, remaining the ultimate gold standard for brewers looking to anchor their brewhouse with historical authenticity.

The sensory footprint of Yakima Cluster is a wonderfully unpretentious, vintage American masterpiece that intentionally prioritizes deeply rustic, clean botanical notes over the flashy, tropical-candy saturation of contemporary craft hybrids. The aromatic canopy opens aggressively with an assertively woody and earthy foundation, evocative of rich garden soil and fresh wild field grass. These deep, grounding elements seamlessly transition across the palate into a pleasant, old-school floral bouquet resembling dried lavender and wild meadow blossoms, before finishing with a distinct, dark-fruit undertone reminiscent of dried blackcurrants. Boasting a robust, time-tested essential oil matrix and a clean, firm alpha-acid percentage, Yakima Cluster functions as an incredibly reliable dual-purpose asset. It delivers an exceptionally smooth, uniform bittering base when tossed early into the kettle, while adding a beautifully structured, nostalgic continental-style depth when utilized in traditional late-boil additions or whirlpool infusions.

Substitution Tip

If you can't find Yakima Cluster, the best alternatives are California Cluster, Chinook, Eroica, Galena, or Northern Brewer.
