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.
Sonoma is a large and diverse region. Whereas its neighbor, Napa Valley, is small and compact, Sonoma sprawls for miles. Many of the best vineyards are located north of the city of Santa Rosa, and south of the town of Cloverdale. There you'll find a concentration of superb vineyards in the Alexander and Knights Valleys. Varietal diversity rules here, with excellent versions of any number of different California wines, including Cabernet Sauvignon, Zinfandel, Merlot, Sangiovese, Syrah, Zinfandel, Chardonnay and Sauvignon Blanc.
