MAJOR TRAITS: Pleasant "noble" aroma suitable for production of super premium beers, mild bitterness, particularly suited for production of Pilsner-type beer.
OTHER INFORMATION:Very poor clustering, usually only two cones per side arm node. Identical to USDA 21525, except for freedom from viruses; commercial planting established at the Anheuser Busch BARI Hop Farms, Bonner's Ferry, Idaho in 1990 adjacent to the Canadian border where summer day length is 1-2 hours longer than in the Yakima Valley or in the Willamette Valley. Commercial yields at that location reportedly exceed 1000 lbs/acre. Not grown commercially anywhere else in the United States. Closely related (perhaps identical) to USDA 21077.
