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!!
There are 2 bottles in a magnum
30
it matters with how many milliletres are in it
A Nebuchadnezzar of Champagne by volume is 15 Liters, or 20 750ml bottles or 3.9625808 gallons.
A methuselah is an over sized bottle which contains approximately 6 liters wine/champagne
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.
A Jeroboam of MoΓ«t & Chandon typically contains 3 liters of Champagne, which is equivalent to 4 standard bottles or around 20 glasses of Champagne.

Different companies have different sizes for their Magnum (which just means big) bottles. 1.5 liters, 2 , 2,5, even 5 liter bottles exist. Count on 0.15 liter per serving (that's about half a cup - maybe a little stingy but anyway). A Magnum of Champagne is 1.5 litres or two regular bottles of Champagne, It will provide about 20 Champagne flute size servings.
