(PressDemocrat) - Jackson Family Wines announced a deal Thursday to buy the sprawling Russian River Valley ranch owned by Saralee and Richard Kunde, who hosted some of the region's most popular fundraisers among their vineyards and helped raise millions of dollars for the agriculture community. The 260-acre site off Slusser Road includes Richard's Grove and Saralee's Vineyard, where the Kundes planted grapes in 1988. Today, it has more than 200 acres of top-quality vineyards, including more than 50 clonal selections of grapes sold to 45 wineries.
