Patron Dinner at Trinchero Family Estates

In 1948 Mario Trinchero and his family made their way west to build a better life. They purchased an abandoned Prohibition-era winery in St. Helena, refurbished it, and scraped by as a mom-and-pop operation. Seven decades later, Trinchero Family Estates is one of the largest family-owned wine companies in the United States.
