How much alcohol is in a bottle of Champagne?
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.
