Of all the New World wine countries, perhaps the one which has demonstrated the most flair for producing high quality wines - using a combination of traditional and forward-thinking contemporary methods - has been the United States of America. For the past couple of centuries, the United States has set about transforming much of its suitable land into vast vineyards, capable of supporting a wide variety of world-class grape varietals which thrive on both the Atlantic and the Pacific coastlines. Of course, we immediately think of sun-drenched California in regards to American wines, with its enormous vineyards responsible for the New World's finest examples of Cabernet Sauvignon and Merlot based wines, but many other states have taken to viticulture in a big way, with impressive results. Oregon, Washington State and New York have all developed sophisticated and technologically advanced wine cultures of their own, and the output of U.S wineries is increasing each year as more and more people are converted to their produce. The beautiful sub-region of Walla Walla sits within the vast Washington State wine region of Columbia Valley, in the dry and arid, gently sloping lowlands which typify the area. The region has been building up a powerful reputation over the past few decades, and dozens of wineries have opened within the sub-region of Walla Walla over the past twenty years, helping it establish itself as a force to be reckoned with in the world of United States wines. Walla Walla is internationally renowned for the high quality of its Cabernet Sauvignon and Merlot varietal wines, made from imported French grape varietals which adore the dry and arid soils which are found within the region. However, many grape varietals thrive within Walla Walla, and wineries are now expanding their portfolios and creating a wide array of wines.
