The purple Malbec variety grapes which now grow all over the Old and New Worlds had their origins in France, where they are one of the few grape varieties allowed to be used in the highly esteemed blended wines of Bordeaux. However, it is perhaps the New World Malbec wines which have attracted the most attention in recent years, as they thrive in hot southern climates in ways they cannot in their native country, where the damp conditions leave them highly vulnerable to rot. Malbec grapes are renowned for their high tannin content, resulting in full-bodied red wines packed with ripe, plummy flavors and held in their characteristically dark, garnet colored liquid. In many countries, Malbec is still used primarily as a varietal for blending, as it adds a great level of richness and density to other, lighter and thinner varietals. However, single variety Malbec wines have been greatly on the rise in recent years, with some fantastic results and big, juicy flavors marking them out as a great wine for matching with a wide range of foods. 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.
