Developed by the USDA breeding program in Washington State and released in 1985 as a high alpha bittering variety, Chinook is a cross between Petham Golding and a USDA male. In recent years, it has found favour as a dual purpose hop in the craft brewing community as a result of its spice and pine aroma characteristics.

Aroma: Specific aroma descriptors include grapefruit, spice, and pine.
