Presentation
For over a century, Domaine Bonnet Gilmert has honed its craft in the heart of the Côte des Blancs, the cradle of great Chardonnay champagnes. Based in Oger a Grand Cru village the estate exclusively cultivates Chardonnay on chalky soils that lend finesse and striking minerality to its wines. While many Champagne houses blend grape varieties, Bonnet Gilmert focuses solely on the purity of Chardonnay. Vinified exclusively in stainless steel, the wines retain their natural tension and freshness. Harvesting is done by hand, ensuring optimal grape selection. Prolonged aging on lees sometimes for up to five years brings out delicate brioche notes and remarkable aromatic complexity, all while maintaining a fine and elegant mousse. These are precision-driven champagnes, distinguished by bright aromas of citrus and white flowers, a silky texture, and a subtle saline finish a pure expression of the exceptional terroir of Oger.
Location
Champagne Bonnet Gilmert Grand Cru Blanc de Blancs Extra Brut is crafted from parcels ideally located in the Grand Cru villages of the Côte des Blancs, including Oger, Le Mesnil‑sur‑Oger, and Avize. These south and southeast‑facing slopes enjoy optimal sunlight throughout the growing season, promoting even and complete ripening of the Chardonnay grapes. The gently rolling hills, combined with a temperate microclimate, provide natural airflow that protects the vines and supports balanced maturation. This exceptional geographic setting imparts refined aromatic precision and clarity that reflect the singular quality of the region’s chalky terroirs.
Terroir
The terroir of Grand Cru Blanc de Blancs Extra Brut is based on deep chalk and clay‑limestone soils, typical of the Côte des Blancs. This geology provides excellent natural drainage while retaining enough moisture to sustain vine growth during drier periods. The chalky subsoil lends minerality, tension, and purity, while clay contributes depth and body, allowing the Chardonnay to mature slowly and fully. This combination produces wines with remarkable clarity, minerality, and expressive complexity. The terroir’s influence is evident in every layer of aroma and flavor.
In the vineyard
At Bonnet Gilmert, vineyard management follows a reasoned and environmentally respectful approach. Soil care focuses on minimal disturbance and controlled ground cover to preserve soil structure and encourage biodiversity. Treatments are applied only when necessary, and always in a targeted manner to maintain vine health. The estate’s sustainable practices include careful resource management and efforts to minimize environmental impact. These commitments help produce healthy, expressive grapes and preserve the vineyard ecosystem for future generations.
Harvest
The harvest for Grand Cru Blanc de Blancs Extra Brut is done exclusively by hand, allowing for meticulous selection of perfectly ripe Chardonnay clusters. Handpicking ensures that only the best fruit enters the press, preserving freshness and aromatic integrity. Each parcel is harvested separately to capture nuanced ripeness levels and terroir expression. Rapid transport of the grapes to the press further protects fruit quality and initiates vinification under optimal conditions. This careful harvesting is essential to achieving the finesse and precision that define this Extra Brut cuvée.
Winemaking
Grand Cru Blanc de Blancs Extra Brut is vinified with emphasis on purity and terroir expression. After gentle pressing, alcoholic fermentation takes place in temperature‑controlled stainless steel tanks to preserve freshness and fruit character. Some lots may undergo partial malolactic fermentation to balance tension and roundness.
Ageing
After blending, the wine undergoes traditional bottle fermentation and is aged on fine lees for about 48 to 60 months, a prolonged period that enriches complexity, refines texture, and integrates the mousse. Minimal dosage typical of Extra Brut highlights the wine’s purity and the terroir’s mineral signature.
