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.
either 6 or 12 if they are standard 750ml bottles.
That really depends on how large the bottle is.
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!!
