Charles Dufour crafts this Bistrøtage B.20 from 100% Pinot Noir harvested in 2020 in the Arce Valley, in the Côte des Bar. The vines are cultivated using rigorous organic farming methods that respect the soil. After manual harvesting and direct pressing, fermentation occurs spontaneously with indigenous yeasts. Part of the clear wine is aged in oak barrels and demi-muids, the other part in stainless steel vats, which provides a beautiful balance between freshness and substance.

The total ageing process, in barrels followed by long ageing on lees, lasts around 42 months before disgorging in June 2025. No dosage is added, and the wine is free from fining or filtration. The result is a sincere, expressive Champagne that is deep, mineral and full of finesse, a fine example of the "vigneron" style of the Côte des Bar.
