Carignan is an ancient blue-skinned grape varietal, thought to be indigenous to the Aragon region of Spain. However, today it is most commonly associated with the fine wines of southern France, and has been grown in many countries around the world which have the warm and dry conditions it requires to thrive. Carignan is recognized as being quite a sensitive vine, highly susceptible to all kinds of rot and mildew, although producing excellent results when given the right conditions and handled correctly. Its high tannin levels and acidity make the Carignan grapes very astringent, and as such, they are often used as a blending grape to give body to other, lesser bodied varietals. Despite this, with careful treatment, Carignan can produce superb single varietal wines packed full of character and unique attributes. 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.
