Tannat is a red wine grape, historically grown in South West France in the Madiran AOC, and is now one of the most prominent grapes in Uruguay, where it is considered the "national grape".^[1]

Tannat is also grown in Argentina, Australia, Brazil, Bolivia, Peru, South Africa, and in the Italian region of Apulia, where it is used as a blending grape.^[2] In the US states of Maryland and Virginia, there are small experimental plantings of the vine, and plantings in California have increased dramatically in the first years of the 21st century. There are small plantings in Washington State which have shown excellent results. It has also been increasingly planted in Arizona, Oregon and Texas.

Tannat wines produced in Uruguay are usually quite different in character from Madiran wines, being lighter in body and lower in tannins. It is also used to make full bodied rosé. In France, efforts to solve the harsh tannic nature of the grape led to the development of the winemaking technique known as micro-oxygenation.
