The purple skinned grapes of the Grenache varietal have quickly become one of the most widely planted red wine grapes in the world, flourishing in several countries which have the correct conditions in which they can grow to ripeness. They thrive anywhere with a dry, hot climate, such as that found in central Spain and other such arid areas, and produce delightfully light bodied wines full of spicy flavors and notes of dark berries. Their robustness and relative vigor has led them being a favorite grape varietal for wineries all over the world, and whilst it isn't uncommon to see bottles made from this varietal alone, they are also regularly used as a blending grape due to their high sugar content and ability to produce wines containing a relatively high level of alcohol. 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.
