From Washington and Idaho’s arid climate to Oregon’s lush Bavarian-like landscape, U.S. hop growers produce a wide range of aroma, alpha and super-alpha hops. This page details alpha hop varieties that are grown in the U.S. It is not a comprehensive list of every hop variety, but rather a guide that describes some of the most popular American varieties used by brewers around the world. 

The Hop Growers of America encourages you to sample the diverse selection of premium hops grown in the United States. Please refer to the merchant contact information under the Site Tools section of this website for information on ordering hops from the USA.

Alpha Varieties...

Chelan
Chelan is a high alpha variety with a very high percentage of beta acids. The variety was developed through the John I. Haas, Inc., breeding program and released in 1994. It is a daughter of Galena and therefore has analytical data similar to Galena.

Chinook
Chinook was developed by the U.S.D.A. breeding program in Washington State and released in 1985 as a high alpha variety.  It has a medium strength aroma profile and is becoming increasingly popular with U.S. craft brewers. Chinook is often used in Pale Ales, IPA’s, Stouts, Porters, and in Lagers for bittering.

Cluster

Cluster is the oldest hop variety grown in the U.S.  Until the late 1970's, Cluster was one of only a few varieties growing in the U.S. and accounted for most of the country’s hop acreage.  It is an excellent general purpose hop with well-balanced bittering potential and aroma properties. The storage stability of its alpha acids is among the best in the world.

Galena
 
Galena
Galena is a high alpha variety that was developed in the Idaho state breeding program in 1978. It has balanced bittering properties combined with an agreeable aroma profile. Galena’s storage stability is excellent.   It has often used in both English and American-style Ales.

Nugget

Nugget is a high alpha variety released in 1983 from the U.S.D.A. breeding program in Oregon. It is characterized by a mild herbal aroma, a low proportion of cohumulone, and good storage stability.  Nugget is the second most widely grown hop variety in Oregon, and also has significant acreage in Washington State.
