80% Mesnil, 10% Oger, 10% Avize For five generations (nearly two centuries), the house that shelters the Champagne J.L. Vergnon has been owned by a single family. In 1950, it was passed to the son, Jean-Louis Vergnon, who recreated his vineyards on the slopes of Côte de Blancs in Mesnil/Oger. Classified Grand Cru, it is renowned for the excellence of its soil and is exclusively growing Chardonnay. Here, East-facing vineyards grow above chalky subsoil. The blending of several plots from his different Crus, with different exposure, of over 30 year old vines on average, allow Jean-Louis to achieve great balance in his Champagne.
