Known as Côt throughout much of France, Malbec is the dark-skinned variety that put Argentinian wine on the map - and likewise, Argentinian Malbec saved the grape from near obscurity. The Cahors appellation in France still relies on Malbec to distinguish many of its wines, but the area is exceptional in this regard. As the grape can be quite difficult to cultivate, it has become far less popular over the years, even in its Bordeaux home. Its South American renaissance has ensured, however, that Malbec will be sticking around for a while.
