In a statement, E. & J. Gallo Winery announced the purchase of Columbia Winery and Covey Run Wine from Ascentia Wine Estates. The price was not disclosed.
"We have been watching the Washington wine industry grow for a number of years and consider these wine brands to be a key part of our premium wine strategy moving forward," said Roger Nabedian, senior vice president and general manager of Gallo's Premium Wine Division.
Washington ranks second in premium wine production behind California, with more than 740 wineries and 43,000 acres planted in wine grapes. The state has 12 federally recognized grape-growing regions, known as American viticulture areas or appellations.
The two wineries produce premium wines largely from the Yakima Valley and Columbia Valley appellations, located east of Washington's Cascade Range in an arid region known for its agricultural production.
Located northeast of Seattle in Woodinville, Columbia Winery was founded as Associated Vintners by a group of friends in 1962. The winery employed the late David Lake, a pioneer in the state's wine industry, as head winemaker from 1979 until his retirement in 2005, and was Washington's first premier winery.
Covey Run, another longstanding Washington brand, has been operating since 1982 from its base in Sunnyside.
Steve Warner, president of the promotional Washington Wine Commission, called the news "proof" that Washington is among the global leaders in the wine world.
"This clearly reinforces how distinct and important Washington is in the greater world of wine," he said. "We don't only grow awesome grapes, but we have a great group of wineries that really deliver on the quality, and that's been proven time and time again."
Brothers Ernest and Julio Gallo founded their winery in Modesto, Calif., in 1933, and the family continues to operate the company. Brands include Gallo Family Vineyards, Barefoot Cellars, MacMurray Ranch and William Hill Estate. The winery recently expanded its operations to include distilled spirits.
