Established in 1930, Domaine Michel Vattan is a family-run estate located in Maimbray, a hamlet within the renowned Sancerre region of the Loire Valley. Currently managed by Pascal and Nathalie Joulin, the winery focuses on sustainable viticulture across its 9.1 hectares, utilizing cover crops and avoiding insecticides to preserve the local terroir. Their artisanal approach highlights the distinct characteristics of "Terres Blanches" and "Caillottes" soils, producing mineral-forward Sauvignon Blancs and elegant Pinot Noir rosés that are recognized for their purity and precision.
