The Math of Wine--a Postscript

A unit of alcohol (10 milliliters of ethanol—the amount the average healthy body can process in an hour) can be determined by multiplying the volume of the drink (in milliliters) by the percentage of alcohol by volume in your beverage and dividing by 1000. For example, a 750 milliliter bottle of wine at 13% alcohol contains 9.75 units of alcohol. An ounce is approximately 30 milliliters (29.57 for you purists out there) so that means that an average bottle of wine is 25 ounces. If you do the math, that means that a unit of 13% alcohol wine is just a hair over 2.5 ounces (2.564 for the purists).
