How many glasses in a bottle of champagne?

There's no single answer to how many glasses are in a bottle of champagne! It depends on:

* The size of the bottle: A standard bottle is 750 ml, but there are also magnums (1.5 liters), jeroboams (3 liters), and even larger sizes!

* The size of the glass: A flute holds about 6 ounces, while a coupe is closer to 4 ounces.

* How much you pour: A full glass is typically 4-6 ounces, but you can pour smaller portions.

Here's a rough estimate:

* Standard bottle (750 ml): 6-8 flutes, 8-10 coupes

* Magnum (1.5 liters): 12-16 flutes, 16-20 coupes

Important note: This is just an estimate. To be more accurate, you'll need to know the specific size of your bottle and glasses.
