For more than a century, Bonnet Gilmert has cultivated its expertise in the heart of the Côte des Blancs, the emblematic terroir of great Chardonnay-based Champagnes. Founded in 1910, this family estate extends over 7 hectares around Oger, Le Mesnil-sur-Oger and Avize, three Grand Cru villages that place it among the region’s most respected names.

Based in Oger, the estate grows Chardonnay exclusively on deep chalk soils, giving rise to Champagnes of remarkable finesse, marked by minerality and elegance. While some houses favour blends, Bonnet Gilmert is dedicated to the purity of Blanc de Blancs, offering an authentic expression of its terroir.

Harvesting is carried out by hand to ensure a rigorous selection of grapes at optimal ripeness. Certified Haute Valeur Environnementale, the estate follows a sustainable approach to viticulture, with close attention paid to biodiversity and soil preservation. In the cellar, the wines are aged exclusively in stainless steel tanks. Extended ageing on the lees brings a fine mousse, silky texture and layered aromatic complexity.
