One of the traditional "Bordeaux varietals", Malbec has characteristics that fall somewhere between Cabernet Sauvignon and Merlot. A midseason ripener, it can bring very deep color, ample tannin, and a particular plum-like flavor component to add complexity to claret blends.
It is known in much of France as Cot, and, in Cahors, also as Auxerrois. There are in fact hundreds of local synonyms, since Malbec at one time was widely planted all over the country. Sensitivity to frost and proclivity to shatter or coulure is the primary reason Malbec has become a decreasing factor in most of France. Although plantings in the Medoc have decreased by over two-thirds since the mid-twentieth century, Malbec is now the dominant red varietal in the Cahors area. The Appellation Controlee regulations for Cahors require a minimum content of 70%.
