Calculate the energy value of your wine

Enter the alcohol, the residual sugar and, if you have them, the total acidity and the glycerol from your analysis. You get the energy value per 100 ml in kJ and kcal, ready for the label.

Energy value per 100 ml

312 kJ / 75 kcal

On the label · E (100 ml) = 312 kJ / 75 kcal

Have this result checked

Factors from annex XIV of Regulation (EU) 1169/2011: alcohol 29 kJ / 7 kcal per gram (density 0.789 g/ml), carbohydrates 17 kJ / 4 kcal, organic acids 13 kJ / 3 kcal, polyols 10 kJ / 2.4 kcal. Use the values of your own analysis.

Which formula does the calculator use?

Grams of alcohol per 100 ml (% vol × 0.789) × 29 kJ, plus grams of sugar × 17 kJ, organic acids × 13 kJ and polyols × 10 kJ; the same in kcal with 7, 4, 3 and 2.4. These are the factors of annex XIV of Regulation (EU) No 1169/2011.

Values from your analysis in g/l are divided by 10 to get grams per 100 ml. Total acidity is usually expressed as tartaric acid. Glycerol is a polyol. If you leave acidity and glycerol empty, the result is based on alcohol and sugar only, which is how most wineries calculate it.

What are typical results?

Most dry wines land between 270 and 330 kJ (65 to 80 kcal) per 100 ml. Alcohol makes up almost all of it. Residual sugar matters for off-dry and sweet wines: 50 g/l adds about 85 kJ (20 kcal) per 100 ml.

Calculated on alcohol and sugar only, rounded. Use the values of your own wine.

Can I print the result directly?

The result is the energy value to print on the label, for example “E (100 ml) = 312 kJ / 75 kcal”. Use the values of your own analysis and round to the nearest whole number. If you want a second pair of eyes, send it to us with your label and we check both.

Declared values are average values. They may come from your analysis, from a calculation based on known values, or from generally established data (Regulation (EU) No 1169/2011, art. 31(4)). Our article on wine calories walks through a full example.

Questions from winemakers

How many calories are in a glass of wine?

A 125 ml glass of dry red at 13.5 % vol has about 94 kcal (390 kJ). A 175 ml glass has about 132 kcal. Sweet wines have more.

Do I need a laboratory analysis to calculate the energy value?

Not necessarily. EU rules allow values calculated from known data. In practice, the alcohol and residual sugar of your routine analysis are enough.
