In 1947, brothers John and Mario Trinchero traveled to St. Helena, California, near the renowned Napa Valley growing region, and purchased Sutter Home Winery. Mario’s son, Bob, joined the company, and in 1975 he developed the revolutionary White Zinfandel varietal. Trinchero Family Estates represents over 27 brands in the United States and Australia, including Sutter Home, Little Boomey, and Trinchero Napa Valley.
