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.

From what I can tell there is the traditional method Blanquette de Limoux, and also a Blanquette de Limoux Methode Ancestrale. And don't forget a traditional method Cremant de Limoux, as well. This is my understanding, but could be wrong.
