How to Calculate Calories in Dry Wine

Nowadays, many wine shoppers are calorie-conscious, choosing hard seltzers and other manufactured diet drinks in a bid to stay healthy. Many dry wines can offer a more-healthful, more-natural and more-flavorful alternative with a similar calorie count per serving.

However, these can be hard to identify, since most wines do not specify calories on the label, and none carry the mandated nutrition labels found on food packaging.

Luckily, if the wine is dry, it’s easy to calculate its approximate calorie count per serving. This is possible because the only significant sources of calories in wine are alcohol at 7 calories per gram, and sugar at 4 calories per gram. Since dry wines contain so much more alcohol than sugar, their alcohol calories alone can provide a reasonably accurate approximation of the total.

What About Wine Calories from Residual Sugar?

As a general rule, dry wines contain only tiny amounts of sugar — less than 10 grams per liter residual sugar if they’re still, and less than 20g/l if they’re sparkling. We can therefore be confident that any wine that in any wine that tastes dry, residual sugar would be unlikely to contribute more than 5 additional calories per 5-oz. glass or 10g/l for bubbles.
