How many calories are in a bottle of wine?
Here are some explanations:
- Calorie (cal) or kilocalorie (kcal = 1000 cal) is a unit for measuring energy, especially heat. In principle, the following applies: 1 calorie is the amount of energy required to heat 1 gram of water by 1 degree Celsius under certain specified conditions such as ambient temperature and pressure. Another unit for this is Joule (J) or Kilojoule (kJ), where: 1 cal ≈ 4.1868 J and 1 J ≈ 0.239 cal.
- The guide value given applies to a representative example wine with 13% alcohol by volume and 5 grams of residual sugar per litre (the "dry" taste includes a residual sugar content of 0.1 to 9 g/l)
The calorie content increases with increasing alcohol and/or residual sugar content. This means:
- Rich, alcohol-rich wines have more calories than light, low-alcohol wines.
- Residual sweet and noble sweet wines have more calories than dry wines.
