Champagne, Prosecco and Sparkling Wine: Carbs per Glass

By the DrinkLeader team · Published 2026-10-12 · Data updated 2026-10-12 · 8 min read

Dry, brut-style sparkling wines (champagne, prosecco, cava) generally list low single-digit carbs per 5 oz pour, while sweet styles such as Asti and moscato list many times more. Across the 264 wines in the DrinkLeader catalog the average pour has 4.6g of carbs and 118 calories. The tables below show how sparkling wines compare.

Why sparkling wine carbs vary

Wine gets its alcohol from fermented sugar. The carbs in the glass are the sugar that was not fermented, plus any sugar added at the end. In sparkling wine, producers often add a small amount of sweetened wine, called dosage, just before final corking, and the amount sets the style on the label. Brut is a dry style. Extra dry, dry and demi-sec are progressively sweeter, and sweet wines such as Asti and moscato keep a lot of their natural sugar. That is why the word on the label is a better guide than the place name.

The calories come from alcohol plus that sugar. The NIAAA's standard drink for table wine is 5 fl oz at about 12% ABV, which is the serving size most catalog wines are listed at. A flute poured generously can exceed that, so count by volume, not by glasses.

Champagne in the catalog

The table lists catalog champagnes with the fewest carbs per serving. We limit it to servings at or under 200 calories so that large-bottle entries do not distort the comparison.

Champagne is a protected name for sparkling wine from a specific French region; some entries in our data use the word loosely, as in "Korbel Brut Champagne", a California sparkling wine. Read the product name and the sweetness level together rather than assuming the region.

Prosecco in the catalog

Prosecco is an Italian sparkling wine, and its label sweetness runs from brut to extra dry. The catalog's prosecco entries, sorted by carbs:

The prosecco and champagne ranges overlap, which is the point: neither name guarantees a number, and the sweetness word and the pour size tell you more. Prosecco rows here also list slightly lower ABV on average, which trims calories a little.

Sweet sparkling wines

Asti and moscato are made to be sweet. They also tend to be lower in alcohol, so the calories look moderate even though the sugar is high.

Compare the carbs column with the brut tables above. The jump is the difference between a dry and a sweet style, and it is often several times the carbs for roughly the same pour.

All wines for context

Out of 264 wines in the database, 214 list 5g of carbs or less per serving. The range runs from 0.0g to 22.5g. Dessert and fortified wines are at the top. See the broader wine carbs and calories guide for red, white and rosé.

Lower-strength sparkling wines also appear in the low-ABV guide.

Sparkling cocktails and ready-to-drink options

Mimosas, bellinis and canned sparkling cocktails add juice or fruit puree to the wine. Canned cocktails as a group average 13.4g of carbs, so the juice matters. A sparkling mimosa-style can will usually list more carbs than a plain brut pour:

Reading a sparkling label

• Brut is a dry style; extra dry, dry and demi-sec are sweeter. Look for the word on the label.
• Check the serving. A 5 oz pour is the NIAAA standard; a bottle split or a big flute is different.
• Watch ABV. A sparkling wine at 7% is a weaker drink than one at 12%, even if the sugar is higher.
• Be wary of per-bottle figures. Some data sources list a whole bottle, which is why a few catalog entries show a larger serving and more calories.
• Pair with water. It does not change the numbers, but it does slow the pace of drinks.

Serving sizes and a data caution

Sparkling wine data is messier than still wine. Some sources list a 5 oz glass, some a 4 oz pour, and a few list a 12 oz portion that is closer to a half bottle. That is why the champagne and prosecco tables above show the listed serving next to each number, and why the champagne table is capped at 200 calories to keep out entries that clearly describe a larger portion. If you see a calorie figure that looks high for a glass, check the serving column before concluding the wine is heavy.

It also helps to remember what the NIAAA standard drink measures. A 5 oz pour at about 12% ABV is one drink; an 8 oz glass of the same wine is closer to a drink and a half. Prosecco bottled at around 11% is slightly lighter per ounce than champagne at 12.5%, but a bigger flute erases that difference quickly. Counting ounces is the most reliable way to compare, and the numbers in this guide are only as precise as the label or manufacturer page they came from.
