Prosecco is relatively low in calories compared to most alcoholic drinks. A standard 5-ounce glass contains roughly 80 calories at around 11% alcohol by volume. That puts it in a similar range to dry white wine and champagne, though the exact number shifts depending on which style of prosecco you pour.
Calories in Prosecco vs. Other Wines
When you compare prosecco to other popular wines glass for glass, the differences are modest but real. A small 3.4-ounce pour of prosecco comes in at about 83 calories, while the same serving of dry white wine or dry red wine runs about 74 calories. Sauvignon blanc lands at 81, and Riesling at 80. Cava, the Spanish sparkling wine, is slightly leaner at 75 calories for the same pour.
The reason prosecco edges slightly higher than dry still wines comes down to residual sugar. Most prosecco retains a touch more sweetness than a bone-dry sauvignon blanc, and sugar adds calories. That said, the gap is small enough that prosecco still qualifies as one of the lighter options on a wine list, especially compared to dessert wines, cocktails, or full-bodied reds that clock in well over 100 calories per glass.
Why Sweetness Level Matters Most
Not all prosecco is created equal when it comes to calories, and the label tells you a lot. Prosecco comes in several sweetness categories, and they range more widely than most people expect:
- Brut: 0 to 12 grams of residual sugar per liter. This is the driest widely available style and your lowest-calorie option.
- Extra Dry: 12 to 17 grams per liter. Despite the name, this is actually sweeter than Brut.
- Dry: 17 to 32 grams per liter. Again, the name is misleading. This is one of the sweeter styles.
The naming is counterintuitive, and it trips people up. “Extra Dry” sounds like it should have less sugar than “Brut,” but it’s the opposite. If you’re watching calories, Brut is the style to reach for. Even drier options exist: Brut Nature and Extra Brut sit at the very bottom of the sugar scale, with little to no sugar added after fermentation. These aren’t as common on store shelves, but they’re worth seeking out if minimizing sugar and calories is a priority.
Carbs and Sugar Per Glass
A standard 5-ounce glass of prosecco contains roughly 1 to 2 grams of carbohydrates, nearly all of which come from residual sugar. That’s a small enough amount to fit comfortably into most low-carb eating plans. For context, a single grape has about a gram of sugar, so a glass of brut prosecco delivers very little sweetness in absolute terms.
Prosecco has no fat and negligible protein. Its calories come from two sources: alcohol and sugar. Alcohol itself is calorie-dense at 7 calories per gram (compared to 4 for sugar and carbs), which is why even a completely sugar-free wine still has plenty of calories. This means the alcohol content matters just as much as the sweetness level. A prosecco bottled at 12.5% ABV will have noticeably more calories than one at 11%, even if the sugar content is identical.
How to Choose the Lowest-Calorie Prosecco
Look for two things on the label: the word “Brut” (or “Brut Nature” or “Extra Brut”) and the lowest alcohol percentage you can find. Together, these two factors determine the calorie count more than anything else. A Brut prosecco at 11% ABV will sit right around 80 calories per 5-ounce glass, while an Extra Dry at 12% could push closer to 95 or 100.
Some brands now market themselves specifically as low-calorie or low-sugar prosecco. A few of these genuinely deliver, with some specialty bottles coming in under 50 calories per serving by combining very low residual sugar with lower alcohol content. If you see specific calorie claims on the label, they’re worth checking, but the Brut designation on any standard bottle already gets you most of the way there.
Serving size also makes a bigger practical difference than most people realize. A standard pour is 5 ounces, but prosecco flutes vary widely in size, and it’s easy to pour 7 or 8 ounces without thinking about it. At that point, your “one glass” is closer to 120 calories. If you’re tracking intake, pouring into a measured glass at least once gives you a useful visual reference.
