Then comes the time when the cellar master will blend several indeed sometimes up to a hundred or more - eaux-de-vie of different origins and ages.

The eaux-de-vie used here must come from one of the six authorised areas or crus : Grande Champagne, Petite Champagne, Borderies, Fins Bois, Bons Bois and Bois Ordinaires.
