Papillon 2022 from Ruppert‑Leroy is a Brut Nature Champagne made entirely from Pinot Noir, sourced from the 'La Fosse' parcel in the Côte des Bar (Aube). Fermented and aged in barrels and demi‑muids with no dosage, it shows a taut, mineral-driven profile reflecting the clay‑limestone soils. The wine is produced according to the estate's biodynamic viticultural practices.
