Hops Production in Washington: The Yakima Valley and Beyond

Washington State grows approximately 75 percent of all hops produced in the United States, a figure that makes it not just a regional curiosity but a structural pillar of the American craft brewing industry. The story centers on the Yakima Valley, a semi-arid corridor in south-central Washington where volcanic soil, abundant sunshine, and reliable irrigation from the Yakima River converge in ways that hop plants find, apparently, irresistible. This page covers how hops are grown, harvested, and processed in Washington; the key decisions growers face; and what distinguishes the Yakima Valley from other hop-growing regions in the country.

Definition and scope

Hops are the cone-shaped flowers — technically strobiles — of the Humulus lupulus plant, a perennial vine that can grow 20 feet or more in a single season. Brewers use them primarily as a bittering and preserving agent in beer, though the aromatic compounds in modern "aroma varieties" have become equally prized. Without hops, most beer would be sensorially unrecognizable.

Washington's hops industry is anchored in Yakima County, which the Washington State Department of Agriculture (WSDA) consistently identifies as the state's single most productive hop-growing county. The broader scope of Washington hops production stretches into Benton and Kittitas counties, though Yakima remains dominant by acreage. The state's total hop acreage has fluctuated around 34,000 to 38,000 acres in recent years — numbers reported through USDA's National Agricultural Statistics Service (NASS), which publishes the annual Hop Stocks and Hop Grower Intentions reports.

Scope note: This page covers Washington State hops production within the context of state agricultural regulations, WSDA oversight, and regional growing conditions. Federal import/export rules for hops, international hop commodity markets, and hops production practices in other states fall outside this coverage. Washington-specific water management practices that affect irrigation allocation for hop yards are related but addressed separately.

How it works

Hop yards are a feat of infrastructure before they're a feat of agriculture. The trellis systems — networks of poles and wire reaching 18 feet high — must be erected years before a yard reaches full production. Rhizomes (root cuttings) planted in spring take three full growing seasons to reach peak yield, which means capital investment precedes revenue by years.

The Yakima Valley's growing success traces to a specific convergence of conditions:

  1. Latitude — The valley sits near the 46th parallel, giving hop bines approximately 15 hours of daylight during peak summer growth, which drives vigorous plant development.
  2. Volcanic soil — Well-drained silt loams derived from ancient Columbia River basalt flows provide good aeration without waterlogging.
  3. Irrigation access — The Yakima River and its federally managed irrigation system (operated by the U.S. Bureau of Reclamation) deliver water to farms that receive only 8 to 10 inches of annual rainfall — far too little for dry-land hop farming.
  4. Low disease pressure — Semi-arid conditions reduce fungal disease incidence compared to wetter hop regions like the Willamette Valley in Oregon.

Harvest occurs almost entirely in August and September. Mechanized harvesters strip bines, then cone separators and kilns — called oast houses — dry the fresh hops from roughly 80 percent moisture down to approximately 10 percent for storage and pelletization. Pelletized hops (compressed ground cones) now represent the dominant commercial format, enabling longer shelf life and easier handling in commercial brewing operations.

Washington's hop yards are explored further on the broader Washington Crop Production page, which situates hops alongside the state's other major commodity crops.

Common scenarios

Three distinct grower profiles define Washington's hop landscape:

Large contract growers — The majority of Yakima Valley acreage is operated by farms growing under long-term contracts with major brewing companies or hop merchants like Yakima Chief Hops or Hop Union (now part of Yakima Chief Hops). Contract lengths of 3 to 5 years are common, providing price certainty but limiting the grower's ability to pivot toward trendy new varieties.

Craft-focused independent growers — Smaller operations — sometimes 50 to 200 acres — growing proprietary or experimental varieties for craft breweries. These farms often command premium pricing but carry more market risk. Spot market hop prices can swing dramatically; in years of oversupply, spot prices have fallen below production cost.

Integrated processing operations — Some of the larger Yakima Valley operations own their own pelletizing and cold-storage facilities, allowing them to capture value beyond raw hop cones. This vertical integration shifts the business model closer to a food processor than a simple commodity farm, with implications for labor classification and food safety compliance under Washington food safety standards.

Decision boundaries

The decisions that define a Washington hop operation's trajectory aren't made at planting time — they're made years before and hinge on a set of compounding trade-offs.

Variety selection is the most consequential. The industry distinguishes between:

Craft beer's growth in the 2010s created enormous demand for aroma varieties, pulling growers toward higher-risk, higher-reward plantings. When craft growth plateaued after 2016 — a trend documented in Brewers Association annual reports — some yards planted heavily in trendy varieties faced oversupply conditions.

Water rights represent the second structural boundary. Hop yards are water-intensive, requiring roughly 2.5 to 3 acre-feet of water per season. Senior water rights in the Yakima Basin are fiercely held; new entrants face significant constraints acquiring adequate water access, particularly as drought conditions create pressure on junior water right holders. The Washington Agriculture overview provides broader context on how water law shapes every crop decision in the state.

Labor availability is the third constraint. Harvest operations compress enormous labor demand into a 4-to-6-week window. Mechanized harvesting has reduced hand-harvest requirements substantially, but skilled equipment operators, maintenance crews, and kilning staff remain essential. Washington's agricultural labor market dynamics — including H-2A visa programs — are addressed in Washington Farm Labor and Workforce.
