6 glasses in a bottle of Champagne
4 to 6 standard champagne glasses per 750 ml bottle. The bottle is technically 25.3 ounces which would indicate that 6 glasses should be expected, but I find if you really fully fill the champagne glass you only get about 4 servings per bottle.
About 12 ounces.
A Jeraboum is approximately 156 fluid ounces. It is a French style bottle used for Champagne, Bordeaux, and Burgundy.
About 50.72 ounces.
The number of ounces that a champagne glass holds is about 4 oz. when it completely full. However, most people will not fill it to the brim and this means it holds about 3 oz.
A 750 ml bottle of champagne is equal to about 25 fluid ounces. So if you're using 6oz glasses you could fill four of them up and have a little left over.
It is a 375ml bottle of champagne (half the size of a standard bottle).
How many glasses of champagne you get from one bottle depends on the size of the bottle. You can get six glasses from a 750-mL bottle. A magnum is equal to two bottles and a rehoboam is equal to six bottles.
