Michel Vattan works the chalky terroirs of Sancerre, in the Upper Loire, where Sauvignon Blanc reaches its mineral peak. The winery's portfolio centers on expressions of this single varietal across distinct vineyard sites. Cuvée M.K Sancerre, the flagship, has earned recognition from Wine Enthusiast and Wine Spectator. Les C-O Sancerre and Cuvée Calcaire Sancerre follow, each drawing character from the limestone and clay soils that define the appellation. These are wines built on terroir precision—high-acid, aromatic, structured by the cool continental climate of the Loire's northern reaches. Sancerre Sauvignon Blanc demands food, rewards patience, and speaks clearly of place.
