Chinook (US)
Chinook was developed by the U.S.D.A. breeding program in Washington State and released in 1985 as a high alpha acids variety. The female parent is one of the English Goldings. The variety grows vigorously in all growing areas and yields best in the Yakima area. Alpha acids content is high while beta acids content is low compared to other high alpha acids varieties. Aroma strength is medium and storage stability is fair. |

The analytical values are typical for each variety at harvest time but values can vary among crop years, growing areas, growers, and with aging after harvest. * Alpha Acids are determined by ASBC spectrophotometric (Hops 6) in the USA. Alpha Acids for extracts are determined by HPLC (Hops 14) in the USA. ** Storage is percent remaining after 6 months at room temperature.  | |
