About Us / Six Sigma Winery, LLC History: Six Sigma Ranch & Winery is located south of Lower Lake in Lake County, California. When we acquired the land in 2000, the 4,300-acre cattle ranch stood out as a place that could fulfill our dreams of sustainable farming and growing grapes while living in natural beauty. We develop the ranch with nature in mind, integrating small vineyard blocks with the native vegetation and providing corridors for the wildlife. A conservation easement donated to the Golden State Land Conservancy is protecting in eternity the habitat of deer, bobcat, turkey, wild pig, bear and other wildlife.
