The winery is located in the municipality of Maumusson in the area Madiran in Southwest France, The owner Alain Brumont is largely responsible for the quality leap in this area. As in the 1970s the INAO limited the tannate share in favor of other varieties, the winegrowers fought under Brumont's leadership against and stockpiled four-fifths of its vineyard Tannat, He experimented with lowest yields, long maceration, frequent racking and long barrel removal. In 1985, he brought the first unmixed Tannat red wine with Bordeaux-format out and caused a great sensation. There are two wineries or wines called Château Bouscassé and Château Montus. The vineyards cover a total of 160 hectares. The two Madiran top reds are made predominantly from Tannat and shares of Cabernet Sauvignon and Cabernet Franc with a long, five-week fermentation pressed and 16 months in new barriques expanded.
The "Château Montus" comes from grape-vineyards in the department of Hautes-Pyrénées. The "Château Bouscassé" grows on loamy limestone soils with over 50-year-old vines in the department of Gers. Tannat produces the flagship of the house called "Montus la Tire", which matures in barriques for several vintages such as 1994 and 2000 over five years. The second wines are called "Domaine Meinjarre" and "Torus". In both areas also dry and sweet white wines are under the AOC name Pacherenc du Vic-Bilh produced. Besides, too IGP wines (Land wines) generated.
