The Mazzoni-Live Oak vineyard is actually two separate small vineyard blocks that are separated by Live Oak Road in Oakley. They were once owned and farmed by two Italian immigrant farmers named Spike and Guido Mazzoni. The Mazzoni block is made up of predominately Zinfandel vines but is a field blend with Petite Sirah, Carignane, Mataro, and Alicante Bouschet with a few vines of Muscat of Alexandria as well. The 1.5-acre Live Oak block across the street is 100% Zinfandel. Together, the 2015 Mazzoni-Live Oak is 76% Zinfandel, 4% Mataro, 4% Carignane, 13% Petite Sirah, and 3% Alicante Bouschet. The wine is dark black and blue color to the edge, with raspberry, boysenberry, violets, supple tannins and perfect acidity. The wine shows staggering ancient (130 year-old) vine concentration with a briary density and silky, velour-like mouthfeel which is classic of this vineyard.
