History
Michael Muscardini founded Muscardini Cellars more than fifteen years ago, forging deep relationships with Sonoma growers to source fruit for Italian blends and non-Italian varietals made with an Italian winemaking approach. His grandfather made wine in Italy before emigrating to America in 1909. Fifteen years ago, Michael Muscardini first blended Sangiovese, Syrah, and Cabernet grapes to create his signature Tesoro, an homage to his grandfather and his Italian heritage. The Tesoro swiftly became the winery's flagship label, with numerous vintages receiving 90+ point ratings and "Best of Class" awards at various competitions. Michael Muscardini founded Muscardini Cellars to celebrate family, fellowship, and the storied Italian culture, inspired by his grandfather and frequently extended holidays to Tuscany.
