Building a successful Napa Valley winery is hard to do. Building a historically accurate authentically-styled, 13th-century medieval Tuscan-style castle is taking your dreams and ideas to the next level. Dario Sattui has done just that. As a child, he was fascinated by the stories and photos of the old winery his great-grandfather and San Francisco California pioneer vintner, Vittorio Sattui had built. Dario was an entrepreneur and loved playing sports. He started various businesses in grammar school, high school, and college and gained valuable experience in the basics of business but the dream of re-establishing his great grandfather’s original V. Sattui winery which had been dormant for more than 50 years remained.
