What’s the difference between ordering a split of Champagne and a magnum of Champagne? The magnum is actually eight times larger than the split. Traditionally, wine is bottled in ten different sizes, and the names can get rather confusing. A standard bottle is 750 mL, or ¾ of a liter. A half-bottle, also known as a demi, is pretty straightforward, while a split is half of that, or ¼ of a standard bottle. The magnum is the equivalent of two standard bottles, while larger sizes are named typically after ancient kings and biblical characters.
