The average bottle of champagne produces 6 servings, when served in fluted glasses. That is a full flute. If your guests are not big champagne drinkers, you can get by with serving half a flute: have the servers pour as the give the glass to the guest. The bubbles foam to the top of the glass, but when they subside, there is really just half a glass of champagne. So, 25 bottles of champagne serve 150 full glasses and 13 bottles serve 150 half glasses.
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.
That really depends on how large the bottle is.
either 6 or 12 if they are standard 750ml bottles.
Normally you would work it out to roughly six glasses from a standard bottle of champagne so 30 people would be 5 bottles, but i would round it up to six!!
