The techniques of sparkling winemaking did not originate with the Benedictine monk Dom Pérignon, nor was the first purposely sparkling wine produced in the region of Champagne. Regardless, through centuries of refinement Champagne has become the world’s leading sparkling wine and the vinous embodiment of luxury and celebration.
Matt,
I recently received the new version of Christie's World Encyclopedia of Champagne and Sparkling Wine and they claim that as of 2007 Chouilly and Tours-sur-Marne are grand crus whatever authorized grape variety is grown (and the same applies for 1er crus Cuis, Etrechy, and Grauves).
I tried poking around the CIVC's website but couldn't find anything to verify.
