Domaine de Bel Air has 14 hectares of Sauvignon Blanc vineyards on different soils: Kimmeridgian limestone, clay-chalk (argilo-calcaire) and sandy chalk. The finished wine is a blend of parcels planted on three different soil types, giving a wine with added complexity and depth. The vineyards are south-facing and benefit from a favourable microclimate thanks to their very close proximity to the River Loire, which moderates the cold temperatures of the region, encouraging greater ripeness and flavour development.
