The UMC extends its thanks to the writers, historians and photographers who so generously agreed to make their works publicly available on our website. Special thanks go to:

  • Colonel François Bonal, Eric Glâtre, Patrick Demouy, Jacques Mambret, Yann Harlaut, for their contributions to the Encyclopédie du Champagne;
  • Dr Tran-Ky for his insights on the health effects of Champagne;
  • Alain Tricot for the "Cathédrale de Champagne" website;
