For twenty years, this beautifully designed winery perched on a mesa in the Santa Ynez valley north of Los Olivos has been producing wines with mixed results. Recent vintages suggest that the quality of the Chardonnays and Cabernets is moving upward. The 1991 Chardonnay-Barrel Fermented is an attractive, subtle, elegant wine with a graceful, apple blossom and orange-scented bouquet, medium-bodied flavors, admirable acidity, and a fine finish. It is one of the best Chardonnays Firestone has made in years. Tel. (805) 688-3940
