The 1990 Chardonnay from the Sangiacomo Vineyard is the finest Chardonnay winemaker Joel Peterson has ever produced. This explosively rich wine is profound, with tightly knit, powerful, concentrated, spicy, richly fruity flavors, zesty acidity, and whopping length. This super bottle of Chardonnay should prove to be uncommonly long-lived by California's standards. In a blind tasting, I would wager that most people would think it to be a grand cru from Burgundy's Cote d'Or.
