The caloric content is calculated based on the macronutrient composition: Alcohol provides 7 kcal/g, fat provides 9 kcal/g, protein provides 4 kcal/g, and carbohydrate provides 4 kcal/g. Thus, the total kcal is calculated as follows: (3g alcohol * 7 kcal/g) + (25g fat * 9 kcal/g) + (5g protein * 4 kcal/g) + (38g carbohydrate * 4 kcal/g) = 21 + 225 + 20 + 152 = 418 kcal. Water and cholesterol do not provide calories.
