The hills located on the Eastern part of Sancerre Appellation (overlooking the Loire river) have a Terroir made of clay-siliceous soils composed of flint (Silex), clay and siliceous conglomerates. This rare Terroir (20% of the Sancerre Appellation) gives a unique style to the Sauvignon Blanc and is therefore the most sought-after. The flint has the capacity to capture and reflect the heat from the sun (grapes ripen earlier) and transmit to the wine its distinguished acidity. Thanks to a rigorous work and constant attention, J. de Villebois captures the magical association of the Flint Terroir and the Sauvignon Blanc grape variety.
