Like the Fleur de Craie, the Carnet de Léone is produced from 100% Bassuet Chardonnay, but with two distinctions: oak aging and an impressive 78 months on the lees. The result is a Champagne of extraordinary depth and complexity while retaining exceptional precision. The base vintage is 2017 with a dosage is 4 grams per litre. It was disgorged in December 2024.
