Chinook is a very distinctive dual-purpose hop used in Ales for bittering, flavor, and aroma. Developed by the USDA breeding program and released in 1985 as a high-alpha variety, Chinook eventually found traction among craft brewers as a unique aroma and flavor hop. Its ancestry includes Petham Golding and USDA 63012. Thanks to its high alpha content and moderate cohumulone, Chinook delivers potent, smooth bitterness. Used a lot in IPA's, it has distinct medium intensity spice and pine characteristics with subtle notes of citrus and dried herb. Some consider the bittering quality of this hop is a bit rough because it lingers in your mouth after swallowing, however, some brewers can't get enough.
