Six Sigma Ranch, Vineyard & Winery

Situated 50 minutes north of Napa Valley in California’s Lake County, Six Sigma Ranch, Vineyards and Winery offers visitors unparalleled natural beauty and rich history.

The 4,300-acre estate has 50 acres planted to vines, with the bulk of the high-altitude ranch dedicated to a nature preserve. A 2-mile drive into the property meanders along the old stagecoach route and brings you to the tasting room, the original stagecoach stop.
