Madiran is the pilgrim's wine: poured on the roads to Compostela at least since the eleventh century, when the priory of Madiran stood on the route and its vineyard refreshed those passing through Gascony. Tannat built the wine's reputation as a fortress — black, deeply tannic, made for confit de canard and for cellars measured in decades.
The grape's grip also made Madiran a laboratory. Micro-oxygenation — feeding a controlled thread of oxygen into fermenting and ageing wine to soften tannin — was invented here by Patrick Ducournau in 1991 and spread from these hills to wineries worldwide. In the 1990s the "French paradox" studies gave Tannat's procyanidins a brief scientific celebrity, casting the region's sternest red, for a moment, as the most healthful in France.
