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."
St. Helena AVA is at the northern end of Napa Valley just north of Rutherford and south of Calistoga. It is a relatively warm climate thanks to the Mayacamas Mountains on its western edge, which protect it from Pacific Ocean fog. Out of the 9,000 acres in the appellation, some 1,500 are under vine. The principal grapes grown in St. Helena are the Bordeaux grapes of Cabernet Sauvignon, Cabernet Franc and Merlot. St. Helena is considered prime wine producing territory, and it was one of the first important wine producing regions in northern California. The legendary Charles Krug founded his winery just north of the town of St. Helena in 1873, and today the appellation is home to many prestigious producers, including Abreu, Grace Family and Spottswoode.
One of the most widely grown grape varieties, it can be found in nearly every wine growing region. A cross between Cabernet Franc and Sauvignon Blanc. It’s a hardy vine that produces a full-bodied wine with high tannins and great aging potential.
