The grapes come from a south-to-south-easterly-facing vineyard situated at 200- 210 meters above sea level in the Sancerre appellation. The vines have an average age of 20 years and are planted at a density of 8,000 to 10,000 vines per hectare, yielding between 45 hl/ha. The soils are made up of a combination of Terres Blanches (50%), Caillottes, limestone, and clay pebbles, which reflect the sunlight onto the vines, encouraging the ripening of the fruit (40%) and flinty Silex (10%). The vineyard is certified organic, chemical preparations are not employed, and the vineyard has been converted to biodynamic certification. The biodynamic philosophy recognizes the connection between all living things, the importance of biodiversity, and sustainability, following the lunar cycles, earth rhythms, astrology, and the interconnection between these energy sources to dictate the timing of viticultural activity. The vineyard is cultivated manually, except ploughing and the grapes are hand-harvested.
