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.
Just to make sure we're all on the same page, there are still only 319 villages (communes) authorized to grow grapes for Champagne. The 357 number hasn't been finalized as there are a couple communes that are supposed to be deauthorized and they are fighting it. I confirmed on the CIVC's website it's still 319. When I last spoke with them they didn't have an ETA as to when all of this was going to get resolved. You can see my comments on the Compendium for a more detailed explanation.
