Willamette is one of the most widely used aroma hops in the U.S., and most notable among craft brewers. Its mix of oils is above the norm (myrcene up to 55%, humulene up to 30%, and farnesene at 5-6%) brings out an herbaceous spiciness characterized by both floral and fruit notes. With excellent vigor, very good yield and good storage stability, Willamette accounts for 20% of the commercially-grown hops in the U.S.
