There are about 27 fluid ounces in a standard (750 ml) bottle of champagne.
Approximately 27.5 ounces.
25.3 fl oz
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.
There are approximately 50.7 fluid ounces in 1.5 liters of champagne.
About 12 ounces.
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.
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.
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.
The traditional long stemmed champagne flute holds 6 ounces to the rim. The normal serving would be 3 ounces as they are never filled completely to the top for toasts. To figure the answer we take 25.4 and divide that by 3: 25.4 ÷ 3 = 8.47 glasses. Since we cannot fill a glass with .47 of an ounce the answer is 8 glasses would be the yield for that volume of champagne bottle.
About 20. A "regular" wine or champagne bottle is 750 ml, which is a bit over 25 ounces, and a typical "toasting" -sized pour is about 5 ounces, so figure five servings per bottle.
