This grand château sits atop a hill overlooking the entire swath of the Côteaux du Layon appellation as it ambles downward toward the snaking Layon tributary to the Loire River. Through the skilled and low-intervention touch of cellarmaster Vianney de Tastes, this estate’s wines are intensely mineral, deeply typical evocations of Côteaux du Layon, Savennières and Anjou, and their evolution toward organic viticulture—now certified as such—has ratcheted up the wines’ expressiveness and dynamism. The Rosé de Loire is 100% hand-harvested Gamay—a variety whose occasional tendency toward shapelessness is counterbalanced by this cool microclimate—and “L’Astrée” is a wine of ethereally pale color and juicy but controlled fruit, pressed directly and aged for four months in stainless steel.
