How many bottles of wine are in a magnum?

A magnum of wine contains 1.5 liters of wine, which is the equivalent of two bottles of wine. Champagne and sparkling wines, as well as Bordeaux-style wines and Burgundy-style wines all are sold in magnum-size bottles.

Although the United States does not embrace the metric system, wines are sold in variations of the liter. A standard-size bottle of wine is equivalent to 750 milliliters or .75 of a liter, which is approximate to 25 fluid ounces. Other sizes of wine bottles that are available in all three wine styles include:

• Demi (half) - 375 milliliters
• Jeroboam (double magnum) - 4 liters
• Salmanazar - 9 liters
• Balthazar - 12 liters
• Nebuchadnezzar - 15 liters
• Melchior - 18 liters
