Madiran AOC

Overview

Madiran produces some of France’s most powerful red wines from Tannat, a grape so tannic that the region pioneered micro-oxygenation techniques to tame its youthful ferocity. Located in the Pyrenean foothills of southwest France, Madiran combines Atlantic moisture with continental warmth to create ideal conditions for Tannat’s thick-skinned, late-ripening character. The wines are legendary for their deep color, massive structure, and extraordinary longevity. For enologists, Madiran offers essential study in Tannat cultivation, extreme tannin management, and the birthplace of micro-oxygenation technology.
