Malbec is a black, mellow grape variety originally grown in France, in the Loire Valley and Cahors. Long known as one of the six grapes used in the blending of red Bordeaux wine, it is increasingly celebrated as an Argentine varietal wine. It is also grown in the cooler regions of California. It has an extensive listing of synonyms; currently more than fifty.

Malbec is widely planted in Argentina producing a softer, less-tannic driven variety than the wines of Cahors. The best examples of these wines come from the Argentine region of Mendoza.

Malbec is the premier grape of Argentina. It seems to have found a natural home, being used to produce very popular varietal wines. It is now thought that the variety known as Fer in that country is a clone. As a varietal it creates a rather inky red (or violet), intense wine, so it is also commonly used in blends, such as with Merlot and Cabernet Sauvignon to create the renowned red French Bordeaux "claret" blend. In California and other areas it is increasingly being used for the same blending purpose.

Introduced to Argentina by French agricultural engineer Michel Pouget in 1868, there were once 50,000 hectares planted with Malbec; now there are 25,000 hectares. Chile, has about 6,000 hectares planted, France 5,300 hectares and California, just 45 hectares. Malbec is also grown in Australia, New Zealand, British Columbia and northeastern Italy.
