EU regulation 1169/2011 and wine industry self-regulatory proposal requires users (or producers?) to input energy values in kJ and kcal per 100 ml and per serving.
- User Input Table
| Alcohol strength by volume | X % (Prefilled) |
| Grams of sugar per liter | X g/l |
| Grams of organic acid per liter | X g/l |
| Grams of polyols per litre | X g/l |
The value of X supports 2 decimal places, e.g. “5.00” and doesn’t support negative values.
- Formula
Total Energy = Energy of Alcohol + Energy of Sugar + Energy of Organic Acid + Energy of Polyols
E = Volume of wine (ml) * (Alcohol %/ 100) * 0.789 * Cov. factor for alcohol +
Sugar (g/l) * Volume of wine (ml) /1000 * Cov. factor of sugar +
Organic acid (g/l) * Volume of wine (ml) /1000 * Cov. factor of organic acid +
Polyols (g/l) * Volume of wine (ml) /1000 * Cov. factor of polyols
- Energy conversion factor (Annex XV of EU regulation 1169/2011)
| Alcohol | 29 kJ/g - 7 kcal/g |
| Sugar/ Carbohydrates | 17 kJ/g - 4 kcal/g |
| Organic acid | 13 kJ/g - 3 kcal/g |
| Polyols | 10 kJ/g - 2.4 kcal/g |
- Energy per serving
The energy of 100 ml / 100 * volume of serving (ml)
- Example of calculation
- User Input Table
| Alcohol strength by volume | 12 % |
| Grams of sugar per liter | 3 g/l |
| Grams of organic acid per liter | 6 g/l |
| Grams of polyols per litre | 7 g/l |
| Volume of wine | 100 ml |
- Calculation
| E (kJ) | E (kcal) | ||
| Energy of alcohol | Volume of wine (ml) * (Alcohol %/ 100) * 0.789 * Cov. factor for alcohol |
100 * 12/100 * 0.789 * 29 = 275 kJ |
100 * 12/100 * 0.789 * 7 = 66 kcal |
| Energy of sugar | Sugar (g/l) * Volume of wine (ml) /1000 * Cov. factor of sugar |
3 * 100/1000 * 17 = 5 kJ |
3 * 100/1000 * 4 = 1 kcal |
| Energy of organic acid | Organic acid (g/l) * Volume of wine (ml) /1000 * Cov. factor of organic acid |
6 * 100/1000 * 13 = 8 kJ |
6 * 100/1000 * 3 = 2 kcal |
| Energy of polyols | Polyols (g/l) * Volume of wine (ml) /1000 * Cov. factor of Polyols |
7 * 100/1000 * 10 = 7 kJ |
7 * 100/1000 * 2.4 = 2 kcal |
| Total Energy per 100 ml | 295 kJ | 71 kcal | |
- When performing the calculation, enter a value with 2 decimal places
- The final value of total energy is rounded off to zero decimal places, e.g. “295 kJ”

3.3.2.2 Spirit energy calculation
- User Input Table
| Alcohol strength by volume | X % |
| Grams of fat per 100ml | X g/ 100ml |
| Grams of carbohydrates per 100ml | X g/ 100ml |
| Grams of organic acid per 100ml | X g/ 100ml |
| Grams of proteins per 100ml | X g/ 100ml |
| Volume | 100 ml |
The value of X supports 2 decimal places, e.g. “5.00” and doesn’t support negative values.
- Formula
Total Energy = Energy of Alcohol + Energy of Fat + Energy of Organic Acid + Energy of Proteins + Energy of Carbohydrates
E = Volume (ml) * (Alcohol %/ 100) * 0.789 * Cov. factor for alcohol +
Fat (g/100ml) * Cov. factor of fat +
Organic acid (g/100ml) * Cov. factor of organic acid +
Protein (g/100ml) * Cov. factor of protein +
Carbohydrates (g/100ml) * Cov. factor of carbohydrates
- Energy conversion factor (Annex XV of EU regulation 1169/2011)
| Alcohol | 29 kJ/g - 7 kcal/g |
| Fat | 37 kJ/g — 9 kcal/g |
| Sugar/ Carbohydrates | 17 kJ/g - 4 kcal/g |
| Organic acid | 13 kJ/g - 3 kcal/g |
| Protein | 17 kJ/g — 4 kcal/g |
- Energy per serving portion
Energy of 100 ml / 100 * volume of serving (ml)
- Example of calculation
- User Input Table
| Alcohol strength by volume | 40 % |
| Grams of fat per 100ml | 0.03 g |
| Grams of carbohydrates per 100ml | 0.3 g |
| Grams of organic acid per 100ml | 0.02 g |
| Grams of proteins per 100ml | 0.2 g |
| Volume | 100 ml |
- Calculation
| E (kJ) | E (kcal) | ||
| Energy of alcohol | Volume of spirit * (Alcohol %/ 100) * 0.789 * Cov. factor for alcohol |
100 * 40/100 * 0.789 * 29 = 915.24 kJ |
100 * 40/100 * 0.789 * 7 = 220.92 kcal |
| Energy of fat | Fat (g/100ml) * Cov. factor of fat |
0.03 * 37 = 1.11 kJ |
0.03 * 9 = 0.27 kcal |

0.02 * 13 = 0.39 kJ |
0.02 * 3 = 0.06 kcal |
| Energy of protein | Protein (g/100ml) * Cov. factor of protein |
0.2 * 17 = 3.4 kJ |
0.2 * 4 = 0.8 kcal |
