Steep slopes (20-40%) fully south-facing, intense sunshine, covered with large pebbles. Yellow and red clay subsoil. Alain Brumont bought Château Montus in 1980, on the basis of the terroir's reputation in the 18th century. With its large reddish pebbles, this terroir is one of the last traces of the beginning of the Pyrenees, dating back 40 million years. Today's Pyrenees deposit large black pebbles marbled with white in our rivers.
