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.

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.
I am also curious how do they filter the wines after disgorgement during the ancestral method? Aren't they losing the bubbles during this procedure? The Charmat I guess is under pressure! Any further reads about this.
Hi Ivan, in France, it's quite typical to express yields in volume per area units. This accounts not only for the actual yields, but also the limits on pressing volumes. In Champagne, the limit for pressing is 2550 liters per 4000 kilograms, so doing the math, 100 hl/ha is equivalent to about 15,700 kg/ha. This exceeds the rendement butoir (the absolute maximum yield) of 15,500 kg/ha. My understanding is that the actual yields in the vineyard may be higher than this, but anything exceeding this limit may not be made into wine.
