The all-champagne dinner is an exquisite pleasure in which you may fully indulge. Each step and type of dish corresponds to a different style of champagne, and the idea is to work your way up from the more acidic to the less acidic, for example from the lively to the more full-bodied, or from the mild to the hearty. 

It is good practice to provide one glass per type of champagne to avoid mixing, and obviously to leave guests free to finish their glass or not. Your guests will also appreciate a menu presenting the precise name of each champagne and the corresponding dish it is paired with.
