California-based Crimson Wine Group has acquired Seven Hills Winery, located in Walla Walla, Washington, US.

The acquisition will help Crimson expand its portfolio with the addition of a Walla Walla Valley winery.

The change in the winery’s operations is subject to the federal and state regulatory approvals. Several of the family members will continue to take part part in winery operations.

The members who will still remain involved in the winery operations include the founders of the winery, Casey McClellan and his wife, Vicky.

Founded in 1988, Seven Hills Winery was the fifth winery to be established in the Walla Walla Valley.

McClellan will continue his role as the winemaker and general manager of the winery.

McClellan said: "It was critical to our family to transition Seven Hills Winery into the right hands, and Crimson’s commitment to producing quality wines from the best-of-class vineyards and wine estates is well aligned with our philosophy.

"We are confident Crimson will preserve the integrity of what my family has built over the years, while providing the resources to take our wines to the next level."

Seven Hills Winery sources fruits from various Washington marquee vineyard sites such as the Seven Hills vineyard, McClellan Estate Vineyard in the Walla Walla Valley, and Klipsun and Ciel du Cheval on Red Mountain.

Crimson Wine Group president and CEO Patrick DeLong said: "We are constantly evaluating the market for the right growth opportunities and fit, and Seven Hills Winery is a strategic match for Crimson.

"The acquisition of Seven Hills Winery is complementary to the Crimson mission and portfolio, adding a high-quality growing region that excels in the production of Merlot and Bordeaux-style red blends."
