What Contributes to Wine's Calorie Count?
Understanding where wine's calories originate is the first step in making an informed, low-calorie choice. The calorie content is determined by two primary factors: alcohol by volume (ABV) and residual sugar.
Alcohol Content (ABV)
Alcohol (ethanol) contains approximately 7 calories per gram, making ABV a significant factor in a wine's total calories. Higher ABV wines will have more calories than lower ABV wines, assuming similar residual sugar levels.
Residual Sugar
Residual sugar (RS) is the unfermented sugar remaining after fermentation. Drier wines have less RS as yeast consumes more sugar. Sweeter wines retain more sugar because fermentation is stopped earlier. Each gram of sugar adds about 4 calories.
The Lowest Calorie Wines by Type
For those seeking the lowest calorie wine, specific styles offer advantages due to their inherently lower alcohol and sugar levels. Dry sparkling wines and dry white wines are often the lowest in calories, with some lighter-bodied reds also being good options.
Sparkling Wines: Often the Lowest Calorie
Sparkling wines, particularly dry ones, are frequently the lowest-calorie traditional wine choice. Brut Nature and Extra Brut Champagne and Cava are among the driest and lowest in sugar and often have lower ABV, with some Extra Brut Champagne containing as few as 65-80 calories per 5-ounce glass. Brut Prosecco is another light option, with about 80-90 calories per 5-ounce glass.
The Lightest White Wines
Dry white wines with moderate ABV are consistently low-calorie options. Examples include Pinot Grigio (around 122 calories per 5-ounce glass), Sauvignon Blanc (110-120 calories), Albariño (110-115 calories), and Vinho Verde (around 88 calories). Unoaked Chardonnay is also a good choice at approximately 120 calories.
The Best Low-Calorie Red Wines
While typically higher in calories than white wines, some light-bodied reds are suitable for calorie-conscious drinkers. Pinot Noir is a delicate, dry red with moderate ABV and around 121 calories per 5-ounce serving. Gamay (Beaujolais) is another option, averaging around 115-120 calories. Dry Merlot with moderate ABV can also be a decent choice at about 120-123 calories.
Comparison Table: Calorie Content of Common Wines (per 5oz Serving)
| Wine Type | Average Calories | Key Characteristics | 
|---|---|---|
| Non-Alcoholic Wine | 9-15 | Contains virtually no alcohol; ideal for calorie counters | 
| Brut Nature Sparkling | 65-90 | Driest sparkling wine style; very low sugar | 
| Vinho Verde | 88 | Light, crisp white with low ABV | 
| Brut Prosecco | 80-90 | Dry sparkling, often enjoyed in smaller servings | 
| Pinot Grigio | 122 | Refreshing, low sugar, crisp white | 
| Sauvignon Blanc | 110-120 | Zesty, dry white with high acidity | 
| Gamay | 115 | Light-bodied, fruity red (Beaujolais) | 
| Pinot Noir | 121 | Lightest dry red option, moderate ABV | 
| Merlot | 122 | Dry, smooth red; good low-cal choice for reds | 
| Sweet Dessert Wine | ~236 | High in sugar and alcohol, highest calorie count | 
Leading Low-Calorie Wine Brands
Several brands specialize in producing lower-calorie wines by reducing alcohol and sugar. These include Surely Wines (offering low-sugar, de-alcoholized options), FitVine Wine (producing low-sugar, low-calorie varietals), Cupcake LightHearted (with lower-calorie, lower-alcohol wines), Thomson & Scott Noughty (alcohol-free sparkling), and Skinnygirl.
Tips for Choosing the Lowest Calorie Wine
To select a low-calorie wine, check the ABV; lower ABV generally means fewer calories. Look for "Dry" or "Brut" labels, indicating lower sugar. Avoid dessert and fortified wines, which are high in sugar and alcohol. Consider brands specializing in low-calorie options and be mindful of portion sizes; a standard glass is typically 5 ounces.
Conclusion
The lowest calorie wine on the market is non-alcoholic wine, with some options containing as little as 9-15 calories per 5-ounce glass. For traditional alcoholic wines, dry sparkling varieties like Brut Nature or Extra Brut Champagne are the lowest in calories. Crisp, dry white wines such as Vinho Verde and Pinot Grigio are also good low-calorie choices. Lighter-bodied red wines like Pinot Noir offer a reasonable option. By considering ABV, residual sugar, and label terms like "dry" or "brut," you can make an informed, lower-calorie selection.
