Take, for example, the 2014 Zinfandel Rattlesnake, a blend of 96% Zinfandel and 4% Petite Sirah with 85% from the Monte Rosso Vineyard and the balance from other Gallo vineyards. It is aged in all French oak, of which 23% is new. A whopper at 16% natural alcohol, the wine has classic Zinfandel characteristics of Provençal spices, roasted herbs, pepper and oodles of briary black raspberry and black cherry fruit. It cuts a big swath across the palate with loads of glycerin and an unctuous, thick, juicy quality that is provocative. The wine is rich, ripe and ideal for drinking over the next 7-8 years. 5,000+ cases were produced.
