The grapes for the cuvee come from a selected parcel named 'Cul de Loup', which refers to the local tale of the last sighting of the last remaining wolf in Sancerre. The parcel is located in the south of Sancerre, in the village of Thauvenay. The 36-hectare plot is close to the River Loire and sits atop the renowned chalky limestone soils, imparting elegance to the wine through the vine's deep root systems. The vineyard is meticulously farmed with the greatest respect for the environment; for many years, the vines have been cultivated without chemical preparations, biodiversity has been encouraged, and soil preservation strategies have been employed, along with water resource management. In 2019, they were awarded the HVE Level 3 certification, and since 2020, the estate has been converted to organic certification. Harvesting takes place during the cool of the night to maintain freshness.
