Through Washington Vintners, their Walla Walla company that owns Corliss Estate, Tranche Estate and Secret Squirrel wineries, the pair have announced the purchase of San Juan Vineyards in Friday Harbor, Wash.

Financial terms of the transaction were not disclosed in the announcement. The winery is owned by Yvonne Swanberg, who started the business in 1996 with her late husband, Steve, building it into an award-winning, estate-grown winery from the coolest-climate growing region in the state. It is known for its white varietals, Siegerrebe and Madeleine Angevine.

The Corlisses have sampled the wines of San Juan Vineyards as residents of the island during the summer months.

“The winery is an integral part of the community on the island,” Lauri Corliss said in the announcement. “We admire the pioneering vision of the Swanbergs, and we look forward to building on their legacy.”

San Juan Vineyards is the only commercial operating vineyard and winery on San Juan Island, according to the their website. The tasting room operates in a renovated 1895 schoolhouse in the Puget Sound American Viticultural Area.

 The ownership change is effective Feb. 1.

The Corlisses started in the wine business in Eastern Washington in 1999. Grapes for their three existing brands are sourced in the Walla Walla, Red Mountain and Columbia Gorge American Viticultural Areas.
