The vineyards of Domaine Mas Nuy, located in the prized Cru appellation of Faugères, are surrounded by holm oaks, arbutus, olive trees, and aromatic and medicinal plants. Two rivers flow nearby. Many of the vines are planted at higher altitudes which limits erosion, encourages water retention and extends the ripening period. Sea winds supply moisture while quickly drying the grapes and leaves. The vineyard experiences 300 days of sun each year. The terroir evolved from the "Monts de Faugères" geological system, dating from the Visean age. The soils are schist (brown and grey slate) and are some of the oldest soils in France. This soil type delivers freshness in the wines as well as generous minerality and acidity. The terroir also includes shale from the marine deposits of a prehistoric sea. The shale provides both drainage and humidity in the vineyard, retaining up to 40% of its volume in water and storing twice as much heat as limestone. This is why the winemakers say the grapes “ripen at night.” The vines are planted in a contour along the steep slopes to limit erosion and retain water. Sustainable and integrated agriculture is practiced and the domaine is in the process of becoming certified organic.
