California's beautiful and remarkably fertile Sonoma Valley has grown over the decades to become one of the United States' most respected and profitable wine regions, with wineries within the region benefiting from the superb Californian sunshine, low rainfall and wonderfully rich soils. Because of this vital combination of excellent conditions, the region is able to grow a wide range of grape varietals for use in the production of an impressive array of wines, with many different red and white wine grapes flourishing each year and producing excellent and characterful results. The soils have been enriched by volcanic activity, and the presence of geothermal springs, which make this region a unique one, and very much the beating heart of California's ever growing wine industry.
The most important grape of the Northern Rhone Valley, Syrah is quickly becoming one of the most noted grapes planted in America. America's best bottlings hail from the Central Coast, Santa Barbara, Sonoma County and Napa Valley. Syrah displays a spicy blend of black pepper and raspberries, with dark fruit undertones; full-bodied with smoke, tar and tannins. It is made into a few magnificent varietally labeled wines, but is also often the base grape for Rhone-style blends. There are those who believe that the Napa Valley should be planted mostly to Syrah, for it thrives in warm growing regions. In Australia, where it is the most-planted red variety, and in South Africa, the grape is known as Shiraz. While viticulturally identical with Syrah, Shiraz grown in Australia is typically sweeter and riper, with more chocolately notes than pepper and spices.
