Calories in champagne: per glass and per bottle

Short answer: a 100 ml glass of brut champagne contains about 75 calories, a full 750 ml bottle around 560. Most of it comes from the alcohol (about 70 kcal per glass), but a small part from sugar. A brut nature is slightly lighter, at about 72 kcal per glass; a sweet doux is heavier, from around 90 kcal.

Sugars and calories in Champagne

▲ Grams of sugar per glass.

A while ago we talked about dosage in Champagne, which in short expresses the number of grams of sugar per litre. Since then we have received a number of questions about how many kilocalories are actually in Champagne. We looked it up for you.

Calories in drinks

The main thing that provides the calories in a drink is the alcohol. Every standard glass contains roughly the same amount of alcohol, because the higher the alcohol percentage, the smaller the glass. So what makes one drink contain more calories than another?

Mainly sugars. Sweet wine, for example, contains more calories than dry wine. A mixed drink of course contains a huge amount of sugar, from adding soft drinks or fruit juice, for instance.

Also not entirely unimportant is fat. Think of creamy liqueurs. Going for cocktails? These calorie bombs often contain several (also fatty) alcoholic drinks as well as fruit juices, syrups and soft drinks. So plenty of alcohol, sugars and fats.

Calories in Champagne

Champagne consists mainly of 'water'. Followed by alcohol, sugars and a small amount of protein. In the calculation below we assume a glass of 100 millilitres.

Calories from sugar

Roughly speaking, 1 gram of sugar provides about 4 kilocalories. If we assume a Brut Champagne with a dosage of 12 grams per litre, a 100 millilitre glass provides about 5 calories from sugars. On top of this come the calories from alcohol.

Calories from alcohol

An average Champagne glass usually contains 12 millilitres of alcohol. Converted, that is about 10 grams of alcohol. The number of kilocalories that 1 gram of alcohol provides is 7. This means that a glass contains about 70 kcal from alcohol.

Added together, a 100 millilitre glass of Brut Champagne contains about 75 calories. A Brut Nature would provide a maximum of 72 kcal in total and a Doux a minimum of 90 kcal.

Sounds like a fine drink for the balmy summer evenings ahead. Bring it on!
Enjoy responsibly.
