The 1991 Sonoma Old Vines Zinfandel is a big, expansive wine bursting with smoky, peppery, berry fruit. There is significant tannin (which is more noticeable in the 1991 than in the 1990), as well as a big, spicy, sweet nose, and broad, audacious flavors. The purity of fruit is super, and the finish long, lusty, and heady. This wine will benefit from another 6-12 months of bottle age and should last for 7-9 years.
