Since time immemorial, wine has been part of man's daily diet, as well as his culture and rituals. Today, however, wine is no longer considered a proper food, as it was for our grandparents. But it still has a caloric intake. So here is a simple guide for those who want to be aware of how many calories a glass of their sacred beverage has. After all, to know how many calories a glass of wine has, it is enough to do a simple mathematical calculation. For how much to consume, however, common sense always applies, while on how to combine the incomparable pleasure of wine with your figure and health, we refer you to the specific pieces.

Why does wine provide calories?
Wine is a substance resulting from the fermentation of sugars in grapes, which become alcohol. Alcohol develops about 7 calories per gram. The calories realised are lost in the form of heat.
Does wine provide nutrients?
No. Wine does not fulfil the functions of classic nutrients: it provides minerals, but vitamins and proteins are present in low quantities.
How to dispose of the calories in a glass of wine?
If taken in excess of one's energy needs, which vary so much from person to person, the fattening effect of wine is inevitable. The good news is that half an hour of sport (not too mild!) is enough to dispose of a glass of wine, 15 minutes in the case of swimming. Let's repeat together: sport, not walking.

What do wine calories depend on?
The calories of wine depend on its alcohol content and, in the case of sweet wines also on the presence of sugar.
How many calories does a glass of wine have?
The alcohol content indicated on the label (% vol.) tells us how many millilitres of alcohol there are in 100 millilitres of wine.
Referring to a 150 ml glass:
- a glass of dry red wine (of 14-15% alcohol by volume) has on average 110 to 120 Kcal;
- a glass of dry white wine (alcohol content 11-12% vol.) has on average 90 to 100 Kcal;
- a glass of sparkling wine (alcohol content 10-12% vol.) has on average 120 to 150 Kcal, slightly more than dry wines because there may be residual sugar.
How to calculate the calories of a glass of wine?
To calculate the calorie content of a glass of wine specifically from a bottle, simply apply the alcohol unit rule:
1. take the alcohol content indicated on the label (volume %);
2. multiply it by 0.8 (which is the specific gravity of the alcohol);
3. multiply the result by 7 (which is the kcal per gram).
The result gives the number of calories per 100 ml of wine. Caution: this is less than a standard glass.
Is this a millimetre-accurate calculation?
No, because the fructose of any residual sugar - which is the actual sugar component in the case of sweet wines - is not taken into account, but it already gives important indications.
These, the numbers. The rest is magic.
