Why are the First champagne glasses so small? A few days ago I enjoyed champagne using my own flutes and got just over four glasses from the bottle. Last night I had another bottle using BA flutes and got eight glasses! It wasn't a magnum either. Are glasses deliberately small?

I have sometimes wondered at the alcohol consumption of board participants but if based on a glass count their intake would be half their claim.

(PS The BA flutes were borrowed for this occasion.)
