Hops in Oregon
Image of hop flowers  
Hop production began in Oregon in 1932. Since then, Oregon has become the second largest hop producer in the United States. Oregon produces about 17% of the United States market share of hops which is about 5% of hops grown in the world.
The majority of hops in Oregon are grown in Marion County with some grown in Polk County. Oregon grows ten varieties of hops on about 6183 acres.
Hops are used in the brewing of beer for their bitter flavor and aroma. They also enhance the clarity of the beer, provide foam stability, and are a natural preservative.
Hops are inspected for seed content and leaf/stem content. The Oregon Department of Agriculture now offers hop certificates via e-mail. If you would like an official inspection certificate, please e-mail us your grower ID and address, or call the Commodity Inspection Program at (503) 986-4620.
Hops are grown from rhizomes. There is a Hop Quarantine against Powdery Mildew of Hops in Oregon, OAR 603-052-1020 (20.5KB doc).  This Oregon Administrative Rule prohibits the entry of hop roots or plant material from anywhere outside of Oregon except Washington and Idaho. If you have any questions, please call or e-mail the Commodity Inspection Program.
