Willamette Hops Flavor
The king of aroma hops in the U.S. with its modest bittering value and sublime blend of flowers, fruit, earth and spice notes. (Reference)
Hop Growers of America Information
Named after Oregon’s Willamette River, which runs through that state’s hop growing region, Willamette was released in 1976 from the U.S.D.A. breeding program. It is a daughter of the classic English variety, Fuggle, and is characterized by a low alpha content and mild aroma. It imparts a mild, slightly spicy, and pleasant aroma in beer.
