Napa Valley
Founded in 1920 by Italian immigrant Guido Ragghianti, Charter Oak Winery in St. Helena is now run by his grandson Robert Fanucci, who honors the family legacy with original equipment and traditional winemaking techniques—natural fermentation and hand-crafted punch-down methods. Crafting bold Napa Valley reds including Cabernet Sauvignon, Petite Sirah, Zinfandel, and distinctive blends, Charter Oak invites you to join their Underground Secret Society Wine Club.
