SNOB VALUE
Actually, there are a couple of reasons. First, magnum bottles are, in general, less common and therefore slightly more expensive to produce. Second, some (not all) magnums are aged longer before release. Third, it is generally believed that wine ages best in a magnum (there is a lower air/wine ratio) and therefore they are generally more desirable for connoisseurs/collectors who are willing to pay more for the added benefit.
it depends on the size of the pour and the size of the bottle. if it is a 5 ounce pour and you are using standard 750 ml bottles, then you will need about 40 bottles
A bottle of champagne filled with the volume equivalent of 20 standard bottles (15 liters) is called a Nebuchadnezzar.
A three-litre bottle of Champagne is a double-magnum, also known as a Jeroboam. It is the equivalent of four standard bottles of Champagne (the sizing applies to still wines as well).
The standard wine and Champagne bottle contains .75 litre, or 750 ml.A magnum contains the equivalent of two standard bottles: 1.5 l or 1500 ml.There are smaller and larger sizes, but these are not commonly used, except for the half-bottle; the largest are more of novelty value. The very largest is the paramount, which contains 36 standard bottles, or 27 l.The link below has more information on wines, including bottle sizes.
either 6 or 12 if they are standard 750ml bottles.
Magnum, Nebuchadnezzar, Salamanazar, Jeroboam. Those are the only ones I can remember but there are others.
It's called a Balthazar and it's equivalent to 16 regular sized 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!!
It is a 375ml bottle of champagne (half the size of a standard bottle).
The term magnum when referring to champagne is a decription of the size of the bottle.Magnum: 1.5 Liters (equivalent to 2 regular bottles)
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.
You will get six glasses per bottle. You will get more from non-standard size bottles. A Magnum equals two regular 750 ml bottles; a Jeroboam equals four; a Rehoboam equals six; a Methuselah equals eight; a Salmanazar equals 12; a Balthazar equals 16; and a Nebuchadnezzar equals 20 regular bottles of Champagne.
