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. Originating in France yet now grown in many parts of the New World, Chenin Blanc is one of the most versatile and highly regarded white wine grape varietals on earth. These green skinned grapes hold a relatively high acid content, and as such can be used for making still white wines of exceptional quality, as well as superb sparkling wines (such as the Crémant wines of the Loire Valley) and extremely aromatic dessert wines. Their natural transparency means that they are a fine grape for expressing their terroir in the bottle, and winemakers often experiment with this varietal to coax unusual and intense flavors from the grapes, such as allowing the development of noble rot on the fruit in order to make sweet and viscous wines of a unique character.
