Champagne is about 13% alcohol. A bottle is typically 750 mL, meaning 97.5 mL of that is pure alcohol. A shot of liquor is 44.36 mL, though a shot of whiskey, tequila, or vodka is typically only 40% pure alcohol. This means a shot is only 17.74 mL of pure alcohol. Thus a bottle of champagne is the equivalent of 5.5 shots of liquor. Since a fifth of liquor holds about 17 shots, a bottle of champagne is equivalent to a third of a fifth of liquor.
