What brand of Prosecco has the least calories? The ultimate low-calorie guide

December 7, 2025 •

3 min read

A standard 125ml glass of Prosecco has approximately 80 calories, although this can vary between 60 and 120 depending on the wine's style and residual sugar content. Understanding these factors is key to making a healthier choice. This guide identifies specific brands leading the low-calorie market and what to look for on the label.

Quick Summary

This guide identifies the lowest calorie Prosecco brands, explains the impact of residual sugar and ABV on calorie count, and provides tips for selecting diet-friendly options.

Key Points

Extra Brut is lowest: Prosecco labeled Extra Brut has the lowest amount of residual sugar and, consequently, the fewest calories.
Syltbar offers extremely low calories: Brands like Syltbar specifically market and test for low calories, with their Prosecco coming in significantly lower than most competitors.
Lower sugar means fewer calories: Calories in Prosecco are mainly from residual sugar and alcohol, so a drier prosecco with less residual sugar will be lower in calories.
ABV affects calories: Higher alcohol by volume (ABV) contributes more calories, so check the alcohol percentage on the label.
Check the label: The name can be misleading; 'Extra Dry' is sweeter and higher in calories than 'Brut' or 'Extra Brut'.
Zero-sugar options exist: Brands like LoSecco offer completely sugar-free and low-calorie Prosecco alternatives.
Prosecco vs. other drinks: Prosecco is often a more calorie-conscious choice than many other wines and alcoholic beverages.

The Factors That Determine Prosecco Calories

The calorie content in any wine, including Prosecco, comes from alcohol and residual sugar. The fermentation process converts grape sugars into alcohol. Shorter fermentation results in more residual sugar, making the wine sweeter and higher in calories. Longer fermentation leaves less sugar and results in a drier, lower-calorie wine.

The second factor is Alcohol by Volume (ABV). Alcohol provides about 7 calories per gram, so a higher ABV wine has more calories. This is one reason why Prosecco has fewer calories than higher-alcohol wines.

Deciphering Prosecco Sweetness Levels

Understanding sweetness classifications is crucial when searching for the lowest-calorie Prosecco. The labels are determined by grams of residual sugar per liter (g/L). Some names like 'Extra Dry' imply a drier wine than they are.

Here are the classifications from driest (lowest sugar) to sweetest (highest sugar):

Brut Nature/Zero Dosage (0–3 g/L): Extremely dry with virtually no residual sugar.
Extra Brut (0–6 g/L): Very dry, with the lowest amount of calories. This is the category to target for a truly low-calorie option.
Brut (0–12 g/L): The most common style, dry but with a hint of fruitiness. It still represents a relatively low-calorie choice.
Extra Dry (12–17 g/L): Despite the name, this style is sweeter than Brut and has a slightly higher calorie count.
Dry/Sec (17–32 g/L): A sweet wine, often paired with desserts.
Demi-Sec (32–50 g/L): The sweetest Prosecco, with the highest calorie and sugar content.

Focusing on the Extra Brut or Brut classification is a good start. Some brands have created exceptionally low-calorie options. Here are some contenders:

Is Prosecco a Better Low-Calorie Choice?

Compared to other alcoholic beverages, Prosecco is a generally wise choice for those monitoring their calories. The specific style and brand are important. Standard Prosecco can range from about 80 calories per glass, while some low-calorie brands can cut that down significantly. A standard glass of white wine can be around 120 calories, and a glass of Champagne might be around 100-140 calories, depending on the dryness and ABV. Opting for an Extra Brut Prosecco can offer a significant calorie saving.

Conclusion: Making an Informed Choice

When seeking the brand of Prosecco with the least calories, the answer is not a single name but a category of sparkling wines. Extra Brut and Zero Dosage Proseccos, like those offered by LoSecco and Syltbar, consistently feature the lowest residual sugar and, consequently, the lowest calorie counts. Look for the Extra Brut classification on the label. Choose a brand that transparently markets and laboratory-tests for low sugar, such as Syltbar. By understanding the link between sweetness classifications, residual sugar, and alcohol content, it's easy to find a delicious, crisp, and diet-friendly Prosecco that fits your lifestyle.

Frequently Asked Questions

Brut Prosecco is lower in calories than Extra Dry. Extra Dry is sweeter, containing more residual sugar, which increases its calorie count.

Residual sugar is the leftover sugar in wine after fermentation. It affects calories because each gram of sugar contains about 4 calories. A lower residual sugar content leads to fewer calories.

Not all low-calorie Proseccos are organic, but some are. Brands like ThinK Prosecco offer certified organic and vegan Brut options that are also low in sugar and calories.

Yes, Prosecco typically contains fewer calories than other wines, such as red or white wines. This is often due to its lower alcohol content.

Yes, it is possible to find zero-sugar Prosecco. Brands like LoSecco produce a zero-sugar option, which is free of residual sugar.

Estimate calories by considering the alcohol by volume (ABV) and the wine's sweetness level. Alcohol contains 7 calories per gram, and sugar has 4 calories per gram. The higher the ABV and residual sugar, the higher the overall calorie count.

Yes, during fermentation, yeast converts sugar to alcohol. A longer fermentation period allows more sugar to be converted, resulting in a drier wine with less residual sugar and fewer calories.
