Since the 19th century, the LARMANDIER family have been cultivating their vines in the premiers and grands crus of the Côte des Blancs. Chalk is the keystone of these great terroirs. Indeed, among the different production areas of the Champagne appellation, only the Montagne de Reims and the Côte des Blancs are situated on the Campanian chalk which is at the origin of the elegant mineral quality of Larmandier-Bernier Champagnes.
