ALPHA ACIDS: 7.1% (5-year range 6.7 to 8.9%)

BETA ACIDS: 4.3% (5-year range 4.1 to 4.9%)

COHUMULONE: 46%

MAJOR TRAITS: High yield potential, some similarities to aroma hops in taste and flavor perception. Bracts conspicuously turned upwards.

OTHER INFORMATION: Established in Washington, Oregon, and Idaho in 3-acre commercial trials in 1987. These trials were expanded to 100 acres in Washington the following year to produce sufficient hops for Anheuser Busch for plant-scale brewing evaluation. Aquila was officially released in 1994. Anheuser Busch lost interest in this hop and it was discontinued from commercial production in 1996.
