HOW TO CALCULATE THE CALORIES OF AN ALCOHOLIC BEVERAGE BY KNOWING ITS ALCOHOLIC DEGREE
However, in the liver the oxidation of 1 gram of alcohol releases a high amount of energy (7 kcal, against 4 Kcal of carbohydrates and proteins and 9 kcal of fats). However, it should be noted that the alcohol content on the label does not correspond to 1 g of alcohol but to 1 ml of ethanol, which develops approximately 5.6 Kcal (5.53 kcal to be precise).
So to know exactly the calories of a liqueur with an alcoholic strength of 30 (30% vol.) It is necessary to make the following calculation:
0.3 x 5.53 x 1000 = 1659 Kal.
HERE IS THE DEMONSTRATION, FOR LOVERS OF MATHEMATICS
A liter of alcohol at a temperature of 26 ° C weighs 0.79 kg or if you prefer has a density of 0.79.
It follows that the weight of alcoholic beverages can vary from 790 grams (all alcohol and no water) to 1000 grams (all water and zero alcohol)
Let us take the liqueur previously considered as having an alcohol content of 30.
One liter of this liqueur contains 237 grams of alcohol [(30/100) * 790]
considering that one gram of alcohol brings 7 Kcal the caloric content is of
(237 x 7) = 1659 Kcal
exactly the same obtained by multiplying the alcoholic strength by 5.53 for the quantity of liquor expressed in milliliters
