Tannat is mainly found near the French
Pyrénées (Béarn, Basque country, Gascony). The wine is notable for its very high tannin levels and is often blended with
Cabernet Sauvignon,
Cabernet franc and
Fer to soften the
astringency and make it more approachable. In addition to Madiran, Tannat is also produced in
Irouléguy,
Tursan and
Béarn, and it is a minor constituent of
Cahors wine. Modern winemaking in the region has begun to emphasize the fruit more and use
oak aging to help soften the tannins. Now the wines typically spend about 20 months in oak prior to release. A French Tannat is characterized by its firm, tannic structure with
raspberry aromas and the ability to age well. They often have a deep dark color with high level of
alcohol. The rosés produced in Irouléguy go through very limited
maceration time with the skins in order to keep the wines from getting too tannic. The resulting wines are typically full bodied and very fruity. In Béarn both red and rosés are produced from blends that include 60% Tannat and a 40% mix of
Manseng noir, Fer and
Courbu noir. In 1990, Madiran winemaker Patrick Ducournau experimented with adding controlled amounts of
oxygen aeration into Tannat while
fermenting and ended up developing the modern winemaking process of micro-oxygenation. ==Uruguay==
