Château Montus is located in Castenau-Rivière-Basse, in the Madiran appellation in the southwest. Alain Brumontbought Château Montus in 1980. He produced his first vintage of Montus in 1982, and the first vintage of the Cuvée Prestige in 1985, but at the time, the wines did not meet the standards of the AOC laws because the vines were too young. Château Montus benefits from a large terroir, unique in the South-West, with a steep slope with large pebbles on fine clay from the Pyrenees. Montus has been nicknamed "the Pétrus of the Southwest" by a dozen critics for 30 years.
