Mastantuono Winery was founded in 1976 by Pasquale Mastantuono, making it one of the oldest wineries in the Paso Robles appellation. Pasquale Mastantuono had a special talent for making outstanding Zinfandels, and his Zins won many awards. In 2007 he and his wife retired, selling the estate to Donati Family Vineyard of Paicines.
Paso Robles AVA is midway between San Francisco and Los Angeles, and it is considered one of the West Coast’s most exciting winemaking regions. With its hot, sometimes searingly dry and sunny weather, it is especially good country for growing warm climate grapes such as Syrah, Grenache and Mourvedre. Because many Paso Robles wineries have been successful with blending these grapes into Rhone Valley-style wines, it is known as the Rhone zone of California. The AVA was created in 1983 and there are 32,000 vineyard acres. In late 2014 the AVA was divided into 11 smaller sub-appellations, so starting with 2015 vintages labeling will become more specific on Paso Robles wines, which will now also list sub-appellations. Located in San Luis Obispo County, Paso Robles, the town and its surrounding area, was traditionally a farming and ranching region. But from a few dozen wineries in the early 1990s to more than 200 today, the area is quickly becoming known for wine and risk-taking winemakers.
Zinfandel is a black-skinned grape, but 85% of the wine produced is made into a rosy “White Zinfandel.” Red Zin is far more complex and bold, while still being light-bodied. It grows in popularity as winemakers continue to experiment with new styles and blends.
