This is a mathematical method for calculating the calorific value as a sum of the calorific values for the primary constituents in beer as determined through analytical methods.
Suitable for all beverages
The energy value or caloric value of beer is calculated according to Council Directive 90/496/EEC and is based upon the amount of protein, carbohydrate, alcohol, glycerin and organic acids. For performing the calculation, caloric values are attributed to 1 g of each of the following: 17 kJ (4 kcal) of protein or utilizable carbohydrate, 29 kJ (7 kcal) of ethanol, 13 kJ (3 kcal) of organic acid, and 10 kJ (2.4 kcal) of higher alcohols. (Fat is not included in the calculation for beer.)
