Nick Carr on September 2, 2016 0 Comments History of Chinook Hops: The Chinook hop variety is well-known among the American craft brewing world. Its origin was a cross between a Petham Golding and a variety only known as USDA 63102M. The male plant, USDA 63102M, as noted in For The Love of Hops by Stan Hieronymus, was the result of crossing a female Brewer’s Gold and a wild male plant from Utah. The Chinook breeding took place in 1974, by the famous research scientist Chuck Zimmermann while working for the USDA hop breeding program in Prosser, Washington. It then went on to testing under the designation W421-38. A USDA registration number was assigned in 1980, and after another five years of plot testing, it was released to the brewing public in 1985 by hop breeder Stephen Kenny.

For the most part mainstream brewers, like Coors, were only interested in Chinook as a bittering hop. No doubt, craft brewers liked it for the same reasons, but surely its other qualities — that of flavor and aroma — made a captivating impression on them also. Chinook found its home in the Yakima Valley of Washington state and to this day the bulk of the yearly supply comes from Washington hop farmers. It is adapted to both Oregon and Idaho, but has never fared as well in either location, especially in Oregon. There’s even a span of about twenty years when there were no Chinook hops grown in Oregon at all. This may be partially due downy mildew. A disease caused by a fungus-like organism, which is more prevalent in Oregon than in Washington. It also shares the problem of higher alpha acids contributing to hotter bales — and possible combustion — as Centennial hops, and this may have been deemed a legitimate reason to keep most of the crop close to easy cold storage in Washington. Despite these difficulties, the rising popularity of the dual purpose hop, over the last several years, has seen a slow return of the variety into Oregon. In 2010 Indie Hops planted Chinook on Coleman Farms. The acreage in Oregon is still quite small with this June 2016 Hop Acreage Report (PDF) showing 106 acres. Still it’s a start and brewers who tested the early crops seem to have been quite pleased with the profile of the Oregon grown Chinook. Chinook as remained one of top five hops since the American Brewer’s Association started releasing Hop Usage Reports back in 2007. The 2015 report has Chinook as the 3rd most popular hop variety.
