The Pacific coastal states of Washington, Oregon and California produced the majority of U.S. hops in the early 1900s. The end of Prohibition in 1933 resulted in a considerable increase in hop acreage in these states, with Idaho expanding the acreage later, during World War II. California commercial hop production ceased by 1990, and the Pacific Northwest continued to dominate U.S. hop production. In 2018, Idaho moved into second place in hop acreage planted and hop yield.
Hops became more popular in Idaho due to the craft beer industry and the speciality crop has been on the rise since around 2012.
