Origin and Description
Crystal Hops was born in 1983, created in Corvallis Oregon. Drink a Rogue Brutal Bitter, and say colchicine induced tetraploid three times. This type of Hallertau was crossed with USDA 21381M, which is resistant to downy mildew. Out comes a hops variety, which is a half sister of both Mt Hood Hops and Liberty Hops.
Crystal Hops bears a low alpha acid rating of 3.5%-6.0%, and carries a relatively high myrcene oil content. This combination makes it ideal for aroma additions in the wort as it bring with it a mix of woody, green, some floral and fruit notes, with some herb and spice character. Crystal Hops lends itself to a number of beers like Light Ales, such as Goldens, Pale Ales, Aroma for India Pale Ales, and even Stouts and Lagers.
Crystal's ancestral tree suggests it was intended to be disease resistant, and this proves so with its resistance to downy mildew. Acreage of Crystal is on the rise, even though its yield is on the light side. Crystal is fairly easy to obtain, however its profile allows itself of substitution with other varieties including Hersbruck and Hallertau Hops. It is more widely used in the U.S.but can be found in beers from England as well.
