Eureka! Hops

Dual: Aroma and BitteringAlpha 17.0 - 20.0%United States

Eureka! stands as a high-impact, dual-purpose American powerhouse engineered for ultimate brewing intensity and agronomic resilience. Developed and commercialized by the advanced agronomic experts within the Hopsteiner Breeding Program (originally evaluated during field trials as Experimental Variant #05256), this variety was born from a calculated genetic cross between two high-alpha titans: Apollo and Merkur. Thanks to this formidable parentage, Eureka! inherits a massive chemical payload and stands out in the hop yard for its exceptional oil density and robust bittering potential. The vine itself exhibits supreme agricultural strength, establishing quickly to deliver high-volume, uniform yields. Because of its massive oil weight and clean bittering efficiency, it has become a favorite choice for late-kettle, whirlpool, and dry-hop additions in bold, aggressive craft styles.

The profile of Eureka! is a complex, multi-layered, and unabashedly pungent sensory showcase that has earned it the legendary brewhouse reputation of being "Simcoe® on steroids." It bursts open with an intense, front-and-center wave of sticky pine sap, crushed forest needles, and a heavy, "dank" herbal undertone. As this initial resinous canopy settles across the palate, a deep, dark fruit character steps forward, driven by prominent notes of sharp blackcurrant, bruised purple plums, and wild mountain berries. This heavy fruit and forest architecture is cleanly balanced by a refreshing, sharp back-end accent of bitter grapefruit zest and sweet citrus oil. This unique parallel running of heavy dark-fruit esters and aggressive, sticky pine makes Eureka! an exceptional standalone weapon for imparting maximum, unrefined New World character.

Substitution Tip

If you can't find Eureka!, the best alternatives are Apollo, Columbus, or Galena.
