Champagne Marlène Delong was founded in 1966 and is currently managed by two independent winemakers. About ten years ago, they began transitioning to organic viticulture practices. They use indigenous yeast, hand-harvest and handle the grapes, and do not filter their champagnes. Additionally, they have eliminated the use of insecticides. Their entire production process is centered around a deep respect for nature, with natural rhythms honored throughout the wine's evolution. While most of their current champagnes are de facto organic, their first certified organic champagne will be available for sale in 2025.
