Corbières is the largest AOC in Languedoc, and produces red, white and rosé wines. Situated between the Pyrenees mountains and the Aude river, the region has a complex geological history that explains the great variety of soil types (including shale, limestone, sandstone and marl) which contribute to the distinctive character of the wines. The area is also shaped by the strong winds that blow most days of the year. Within AOC Corbières is the Cru of AOC Corbières-Boutenac. The rules for this AOC require Carignan in greater amounts than other areas, especially in Boutenac. Only the best wines receive the Boutenac AOC label.
