California as a wine producing region has grown in size and importance considerably over the past couple of centuries, and today is the proud producer of more than ninety percent of the United States' wines. Indeed, if California was a country, it would be the fourth largest producer of wine in the world, with a vast range of vineyards covering almost half a million acres. The secret to California's success as a wine region has a lot to do with the high quality of its soils, and the fact that it has an extensive Pacific coastline which perfectly tempers the blazing sunshine it experiences all year round. The winds coming off the ocean cool the vines, and the natural valleys and mountainsides which make up most of the state's wine regions make for ideal areas in which to cultivate a variety of high quality grapes. 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.
