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 beautiful wine region of Willamette Valley is located in Oregon, one of the main wine producing states of the USA. As in much of Oregon, Willamette Valley benefits enormously from the long, hot summers the state enjoys, and the mineral rich soils which typify the wine regions found there. Willamette Valley has built up a powerful reputation over the past few decades as one of the New World's leading producers of high quality, flavorful and characterful Pinot Noir wines, as the grapes of the Pinot Noir vine thrive particularly well in the region's climatic conditions. Willamette Valley is a fascinating wine region, and is a fine representative for the state of Oregon. Innovative techniques and wine making methods are fairly commonplace there, and the overall produce of the region seems to get better each year.
