how many wineries are there in washington state
Washington wine Washington wine is wine produced from grape varieties grown in the U.S. state of Washington. Washington ranks second in the United States (behind California) in the production of wine.[3] By 2011, the state had over 43,000 acres (170 km2) of vineyards, a harvest of 142,000 short tons (129,000 t) of grapes, and exports going to over 40 countries around the world from the 850+ wineries located in the state. While there are some viticultural activities in the cooler, wetter western half of the state, the majority (99.9%) of wine grape production takes place in the shrub-steppe eastern half.[4] The rain shadow of the Cascade Range leaves the Columbia River Basin with around 8 inches (200 mm) of annual rain fall, making irrigation and water rights of paramount interest to the Washington wine industry. Viticulture in the state is also influenced by long sunlight hours (on average, two more hours a day than in California during the growing season) and consistent temperatures.[5]
