St. Francis has committed to producing the best wines possible while protecting the environment that produces them and helping preserve Sonoma County as a world-class winegrowing region.
In June, 2013, the California Sustainable Winegrowing Alliance officially certified St. Francis Winery & Vineyards a Sustainable Vineyard & Winery. This certification recognizes years of environmental leadership status in cellar, lab and vineyard green practices, as well as an extensive audit and application process that required several years to complete.
