Franck Pascal’s career is unusual: trained as an engineer (in industrial machinery design), he returned in 1994, (at the age of 23) to the family property after his younger brother’s accidental death. Very quickly he became aware of the harmful effects of chemicals used in agriculture on the human body. In 1998, he removed insecticides, weed killers, fertilisers and anti-botrytis. One day his father gave him a plot of Pinot Noir, systematically ravaged by mildew. He began to work without pesticides, thinking that if organic farming was successful, it would work everywhere. From the very first year, he was successful. As a result, Franck Pascal did not take long to deploy these organic farming methods throughout the vineyard, moving to a fully biodynamic crop in 2002. The vineyard is dominated by Pinot Noir and Pinot Meunier, planted on clay soils with flint and millstone rock, at low yield, distributed over five municipalities of the Marne valley. Isabelle and Franck Pascal define themselves as winemakers and "creators of emotions". They have achieved a high standard in this category of champagnes with character.

Harmonie is an aptly-named champagne: its equal blend of Pinot Noir density and Pinot Meunier refinement and elegance produces a remarkably well-balanced, harmonious champagne. Produced from the domain's old vines, using grapes from a single vintage, it displays real personality.
