Mercer Wine Estates, a multi-generation, family-owned winegrower with deep roots in Washington State agriculture, said it is acquiring four leading Washington wine brands – Matthews, Tenor, Jaine, and Single Barrel. Terms weren't disclosed

The acquisition strengthens Mercer’s portfolio of vineyard-driven brands and reinforces its longstanding commitment to investing in the people, vineyards, and places shaping the future of Washington’s Columbia Valley, Mercer said.

Mercer Wine Estates has supplied fruit to Avallé, owner of the four brands, for many years, creating deep familiarity with their vineyards, winemaking approach, and quality standards. Formalizing that relationship allows for greater alignment across farming, winemaking, and long-term brand stewardship.

“They’ve got some great strengths, and we’ve got some great strengths. Put them together, and it makes the whole stronger,” says Rob Mercer, president of Mercer Ranches and owner of Mercer Wine Estates.

The winemaking team behind Matthews, Tenor, Jaine, and Single Barrel will join Ali Mayfield and the team at Mercer Wine Estates, adding decades of experience and talent in crafting some of Washington State’s most highly regarded wines. This team – led by Alex Stewart, Hal Iverson, and Andy Ferguson – will oversee winemaking across the expanded portfolio.

Jen Bell will join Mercer Wine Estates as Vice President, leading the Wine Division and overseeing the expanded portfolio. Bell brings nearly 25 years of experience in wine operations and portfolio strategy.

“Maintaining continuity was critical,” Mercer added. “The people behind these wines matter. This transition allows us to preserve what works while giving the brands a strong foundation for the future.”
