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.
