is a European-type aroma hop similar to German Tettnanger. See tettnanger (hop). It was bred in Corvallis, Oregon, in 1988. Its genetics include Tettnanger as well as Hallertauer and Cascade. Santiam is a triploid, which means it produces nearly seedless cones even in the presence of male pollinators. It is adapted to the growing conditions in all major hop-growing areas in Oregon and Washington. In the brewhouse, it can be used as a replacement for German aroma hops. Its yield may be as high as 2,400 kg/ha (2,000 lb/acre), which is significantly higher than that of Tettnanger. Its alpha acid content ranges from 5% to 8% and its beta acid content from 5% to 7%; its cohumulone content is about 22%. It keeps well in storage. Santiam’s essential oil composition is similar to that of Tettnanger, averaging about 30% to 50% myrcene, 18% to 28% humulene, 5% to 8% caryophyllene, and 8% to 14% farnesene. The characteristic humulene-to-caryophyllene ratio ranges from 3.2 to 3.6, which is similar to Tettnanger. Santiam seems perhaps to have suffered from poor marketing—it is a hop little spoken of, despite having very good brewing characteristics.
