The Cocktail Proof Formula. While you cannot know the exact alcohol content of any particular mixed drink, there is a basic formula that's used to estimate a drink's strength: ( Alcohol Content x Liquor Volume / Total Drink Volume) x 100 = % Alcohol by Volume.

Enter the ingredients and amounts using the drop-down menus or the "+ Add it" feature. Also enter the percent alcohol by volume (% alc/vol) for the alcohol ingredients. The % alc/vol, which is half the "proof," can be found on distilled spirits bottle labels or online.

Calculating Cocktail Alcohol Content (Volume of “Strong” x ABV % / Sum of Ingredients) x 100 It’s pretty simple to do this calculation, but here are a couple of notes.

The general formula is to take the volume of your liquor ingredients, multiply it by the percentage of alcohol by volume and divide that by the total volume of ingredients. Then multiply the whole thing by 100. So it’s (volume of liquor x alcohol by volume/total cocktail volume) x 100 For our Cosmo, it would look like this:

Those who are willing to know how this calculation works can check out the "scientific" version here: Alcohol amount in the aqueous alcohol solution Notice: it is assumed that the mixing takes place at a temperature of 20 ° C, strength percentage by volume (vol%) is defined for 20 ° C.

To a first approximation, you can just calculate the volume of pure ethanol in each of the alcoholic ingredients (total volume * %ABV = volume of pure ethanol), add those up, and divide by the total volume of all ingredients. For example, a margarita with 35mL 40% ABV tequila, 20mL 40% ABV Cointreau, and 15mL lime juice would have alcohol ...

750 mL bottle of wine (12% alcohol) = 5.3 standard drinks 9 oz glass of wine (14% alcohol) = 2.1 standard drinks 2 oz shot of spirits (40% alcohol) = 1.3 standard drinks
