Bear Flag 2015 Zinfandel, with its inaugural vintage 2015, honors both the state’s most famous wine grape and the historic Bear Flag Revolt of 1846, when rebels proclaimed state independence and raised the Bear Flag in Sonoma County. Fittingly, Bear Flag turned to Sonoma for their grapes: 78% Zinfandel supported by Petite Sirah and other red grapes, yielding a ripe, full-bodied wine with true Zin character, notes of dark jam and toasted oak.
