More and more I love to explore the unknown.
Three examples : one Champagne Moët & Chandon Grand Crémant Impérial Doux. The archivist of Moët says that this bottle was commercialised between 1941 and 1948. Crémant means that the pressure is weaker than for other champagne, giving a less active bubble, and « doux » means a very sweet champagne.
Champagne Théophile Roederer Extra Dry which means a sweet champagne, very probably from the twenties
Champagne Kruger & Cie 1966 Epernay totally unknown to me.
