For centuries now, the beautiful red grapes of the Barbera varietal have been grown in Italy, where they are prized for their unusual high acid content and low tannins, brought about by their thin skins. The Barbera grape varietal thrives in warmer climates, and has had some success overseas in the new world, where its strongly aromatic flavors of intense hedgerow fruits make it a favorite with wineries and wine drinkers looking for a grape which offers plenty of interesting characteristics. Interestingly, the differences between young and aged wines made from this varietal are quite significant, with younger bottles holding a plethora of berry flavors, including blueberry and raspberry notes, and oak aged wines made from the Barbera grape being much loved for their ability to become extremely complex and spicy, and picking up vanilla flavors from the wood they are barreled in. 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.
