Les Vignobles Montagnac wine cooperative was built in Montagnac in 1937. It soon became the cooperative for the six other surrounding municipalities as well, covering Montagnac, Aumes, Lézignan la Cèbe, Cazouls d'Hérault, Usclas d'Hérault, Nizas and Loupian.
The cooperative produces 2,250 hectares at its two sites of Montagnac and Loupian. When it was built, Montagnac was the largest vinification facility in the Hérault.
Its vineyards stretch from the banks of Thau Lagoon to the foothills of the mountains on the right bank of the River Hérault.
On these diverse "terroirs" (combination of soil and microclimate), Les Vignobles Montagnac produces equally diverse wines. Its range comprises the controlled origin wines of AC Picpoul de Pinet, AC Coteaux du Languedoc (red and rosé), AC Coteaux du Languedoc Grès de Montpellier and AC Coteaux du Languedoc Terroir Pézenas, as well as red, rosé and white Vins de Pays des Coteaux de Bessilles and the varietals Cabernet, Merlot, Syrah, Sauvignon Blanc and Chardonnay.
Les Vignobles Montagnac represents 750 winegrowers, including numerous wine estates.
