Associated Vintners Acquires Covey Run

Associated Vintners, which owns wineries in Woodinville and Sunnyside, has bought Covey Run Winery of Zillah to become Washington state’s third-largest winery.

Quail Run Vintners and Cellars, a partnership, sold the winery on Monday, but did not make it public until Wednesday. The purchase price was not disclosed.

The decision to buy Covey Run was made in part to take advantage of economies of scale, said Max Zellweger, president of Associated Vintners, which owns Columbia Winery in Woodinville and Paul Thomas Winery in Sunnyside.
