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.
Thanks for the comment. I believe that you’re correct that it’s no longer used. I will update shortly!
Perrier-Jouët "Belle Époque" (bottled as "Fleur de Champagne" for the US market) - Is this still accurate? Some reports online suggest that the Fleur de Champagne label was retired in 2011 with the 2002 vintage being the final release--though I have not been able to verify that claim. But in recent times all the bottles I've encountered in the US market have been labeled as 'Belle Époque' if memory serves . . .

With Charmat, yes, they are filtering under pressure. I'm not totally sure, but I'd imagine that there are bottling machines that help transfer the wine from bottle back to tank without too much loss of pressure. With ancestral method, there is a wide range of practices, some disgorged, some not, etc.
So, I guess I have learned there is a press yield and harvest yield! Thank you Jennifer for clarifying.
