A grape of South-West France
Tannat: origin, taste, appellations, and our organic red wine
A grape rich in tannin, from Madiran to Uruguay.
What is Tannat?
Tannat is a black grape from South-West France, probably from the Béarn, whose name is said to come from the Occitan “tan”, tannin. It gives very dark wines, rich in tannin, with marked acidity. It is the main grape of Madiran, where it must be the majority in every wine; it is also found in Saint-Mont, Irouléguy, Tursan, the Brulhois and Cahors. Brought to Uruguay in 1870, it has become the country’s emblematic grape. It is not one of the AOC Fronton grapes: at Château Saint Louis it goes into La Tour, an organic red IGP Comté Tolosan.

In the glass
What does Tannat taste like?
On its own and young, Tannat is powerful: an almost black colour, tight tannins, acidity that holds it up. That is why it is aged for a long time, often in barrel, or blended with softer grapes, such as Cabernet Franc in Madiran or Négrette here. With time its tannins melt and the wine gains depth.
Young
- almost black colour
- tight tannins
- marked acidity
Blended or aged
- melted tannins
- more suppleness
- ageing potential

At Château Saint Louis
La Tour: Tannat with Négrette
At Château Saint Louis, Tannat is not drunk on its own: it goes into La Tour, blended with Négrette and Syrah. Négrette brings fruit and violet, Tannat brings structure. Each grape is vinified separately; 10% of the wine is aged six to twelve months in oak barrels, the rest in tank.
Because Tannat is not one of the AOC Fronton grapes, La Tour is sold as IGP Comté Tolosan. Like all the estate’s vines, they have been farmed under certified organic agriculture since 2005, on boulbène.
