MAJOR TRAITS: Highly aromatic. Valued worldwide for its noble aroma characteristics as a fine finishing hop for super premium beers.
OTHER INFORMATION: Extreme susceptibility to Verticillium wilt and low yield potential caused steady decline of this hop in the Hallertau, the major German hop growing area. The old Hallertauer mittelfruh has practically disappeared from commercial production, but the trade has accepted a relatively new selection, Hallertauer Gold, as a partial substitute. Not grown commercially in the United States except in a new planting (about 500 acres) of virusfree Hallertauer m.f. near Bonners Ferry, ID. (Ref. A.Haunold. Travel Report to Anheuser Busch Inc., July 1991, 4 pp.).
