Welcome to the home of the world-famous Ranch and Legends West golf course. Diablo Grande AVA is owned entirely by the Diablo Grande Resort Community which encompasses 30,000 acres in total. Wines are produced by the Isom Ranch Winery, which has 36 acres under vine, planted with 10 classic vinifera varietals. The area is named after Mount Diablo, the highest peak in the Pacific Coast Range. Vineyards are between 1,000-1,800 feet, in the western foothills of Stanislaus County. Due to elevation, the Diablo Grande AVA experiences greater rainfall and lower average temperatures than surrounding areas. This is welcomed by greenskeepers and viticulturists alike.
