Six Sigma Ranch and Winery

Six Sigma Ranch and Winery

Six Sigma Winery was inaugurated on September 28th, 2005, when we processed our first grapes, a beautiful vintage of Tempranillo harvested in Christian’s Diamond Mine Vineyard. We focus on small lot, high quality wines, and every aspect of our winery reflects that, from state-of-the-art equipment to gentle handling and meticulous hand-sorting of the grapes, ensuring that only the best fruit is used in each of our wines.
