The Garennes cuvée is a blend dominated by 90% Pinot Meunier, complemented by a touch of Chardonnay and Pinot Noir. The grapes come from the villages of Chambrecy, Damery, Cumières and Hautvillers, with plots laboriously cultivated using organic farming methods, some of which are worked with horses. The vines, some of which are between 30 and 80 years old, grow on south-south-east facing slopes with limestone, clay-sand or chalky soils, ideal for expressing the terroir of the Marne Valley.

After manual harvesting, the must is vinified with indigenous yeasts and low sulphur, then fermented and aged in old oak barrels. Ageing gives the wine structure, density and depth, while preserving its freshness and precision. The blend is based on a multi-vintage principle, with a solera between 2013 and 2022, ensuring continuity and complexity. The final dosage is very low (Extra Brut, approx. 1g/l), allowing the purity of the fruit, the minerality and the natural acidity of the wine to express themselves.
