resulted from a 1983 cross between tetraploid (2n = 40) Hallertauer mittelfrüh and a male aroma hop of unknown parentage. See hallertauer mittelfrueh (hop). It was released in 1989. Mount Hood is a triploid, which means it produces nearly seedless cones even when grown in the presence of fertile males. Mount Hood is well adapted to the growing conditions of the US Pacific Northwest region, where it yields about 1,345 to 2,240 kg/ha (1,200 to 2,000 lb/acre). Mount Hood is similar to its German aroma progenitor Hallertauer Mittelfrueh. It has a nearly identical essential oil profile and, like Hallertauer mittelfrueh, contains only traces of farnesene. But it matures later in the season and has a higher yield and about twice the alpha acid content (5% to 8%). Mount Hood is a suitable substitute for so-called European Noble varieties and can be used as an efficient bittering hop as well as for its aromatic properties. Its storage characteristics are poor, however, and Mount Hood requires immediate cold storage or freezing after drying. See also noble hops.
