Crimson Wine Group has acquired Seven Hills Winery in Walla Walla Valley, Washington state.

The transaction, confirmed yesterday, remains subject to regulatory approvals. Financial details of the transaction were not disclosed.

Napa-based Crimson already has operations in California, Oregon and Washington. The company said several Seven Hills employees would remain involved in winery operations, including winemaker Casey McClellan and his wife, Vicky, who co-founded the winery in 1988. Casey will remain winemaker and general manager. 

The winery currently sources fruit from several Washington vineyards, including Seven Hills vineyard and McClellan Estate vineyard in the Walla Walla Valley and Ciel du Cheval and Klipsun on Red Mountain.

In late-2014, Crimson embarked on a restructure of its management team, with COO Patrick DeLong moving to become CEO.
