Trinchero Family Estates was started in 1947, when brothers John and Mario Trinchero purchased Sutter Home Winery in St. Helena. Since then more recent generations of the family have expanded the business by acquiring numerous brands in the U.S. and Australia, including Ménage a Trois, Napa Cellars and Trinchero Napa Valley. The family’s umbrella business also includes rum and tequila brands. Trinchero Napa Valley is the family’s prestige wine label, and it is mostly single-vineyard wines from the family’s Napa vineyards. Trinchero Napa Valley makes Bordeaux style wines and grows Sauvignon, Merlot, Petit Verdot, Merlot, Cabernet Franc and Sauvignon Blanc. The M. Trinchero label is in honor of Mario Trinchero, and the estate considers its M. Trinchero wines to be "ultra premium."
