Calories in Prosecco: the numbers
Worked out for Prosecco at 11% alcohol, the typical strength:
| Pour | Brut (up to 12 g sugar per liter) | Extra Dry (12 to 17 g per liter) |
|---|---|---|
| 4 oz (120 mL) toast pour | about 75 to 80 | about 80 |
| 5 oz (150 mL) standard glass | about 95 to 100 | about 100 |
| 750 mL bottle | about 475 to 490 | about 490 to 505 |
These are calculated estimates, not lab measurements for any one bottle. The exact figure depends on the wine’s alcohol and sugar.
Where the calories come from
- Alcohol: about 7 calories per gram. A 5 oz glass of 11% Prosecco contains about 13 grams of alcohol, so roughly 91 calories.
- Sugar: about 4 calories per gram. A Brut Prosecco has up to 12 grams of sugar per liter, so a 5 oz glass adds up to about 2 grams, or roughly 7 calories.
That’s why the sweetness word on the label changes the total only a little. A Brut and an Extra Dry are a few calories apart per glass; the alcohol does most of the work.
How to work out your own pour
- Multiply the volume in mL by the alcohol percentage (as a decimal), then by 0.789 (the density of alcohol). That gives grams of alcohol.
- Multiply by 7 for the calories from alcohol.
- Add 4 calories for every gram of sugar (sugar per liter × liters poured).
Example: 150 mL × 0.11 × 0.789 = 13 g alcohol × 7 = 91 calories, plus about 7 from sugar in a Brut, which makes about 98.
Is Prosecco lower in calories than other wine?
Roughly similar. Prosecco is often a little lower in alcohol than many still white wines, which keeps it in the same range or slightly below per glass. Champagne, usually around 12% alcohol, comes out a few calories higher per glass for the same pour and sweetness.
Does the label tell you?
In the US, calorie information on wine labels is optional. Some brands add a “Serving Facts” panel; many don’t. When a label lists calories, use that figure; it’s specific to the bottle.
A standard drink
A 5 oz glass of 11% Prosecco contains about 13 grams of alcohol, a little under one US standard drink (14 grams, per the National Institute on Alcohol Abuse and Alcoholism). How much alcohol is in Prosecco?
