A standard 5-ounce glass of wine contains roughly 120 to 130 calories. That number shifts depending on the type of wine, its alcohol content, and how much residual sugar it holds, but most dry table wines land in a surprisingly tight range. The real calorie swings come from serving size, sweetness level, and whether you’re drinking a light Pinot Grigio or a rich Port.
Calories by Wine Type
For a standard 5-ounce pour of dry red wine, the calorie counts are remarkably similar across popular varietals. Cabernet Sauvignon comes in at about 122 calories, Merlot at 120, and Pinot Noir at 121. The differences between most dry reds are so small they’re barely worth tracking.
White wines are comparable. A 175ml glass (just over 5.9 ounces) of white wine contains around 130 calories. Scale that up to a 250ml glass, which is common in UK restaurants, and you’re looking at roughly 188 calories. A full bottle of white wine runs about 564 calories total.
Fortified wines like Port pack more calories into a smaller volume. A 2-ounce serving of Port contains 94 calories, with about 8 grams of carbohydrates. That’s nearly as many calories in two ounces as you’d find in a full 5-ounce glass of dry red.
Why Alcohol Is the Biggest Calorie Driver
Pure alcohol contains 7 calories per gram, nearly as calorie-dense as fat (which has 9 calories per gram). In a dry wine, alcohol accounts for the vast majority of the calories. Sugar and other trace components contribute very little.
This is why a wine’s ABV (alcohol by volume) percentage is the single best predictor of its calorie count. A quick formula makes this concrete: multiply the ABV percentage by the number of ounces in your glass, then multiply by 1.6. A 5-ounce glass of wine at 13.5% ABV works out to about 108 calories from alcohol alone. A 15% ABV Zinfandel in the same glass jumps to 120 calories from alcohol. Every percentage point of ABV adds roughly 8 calories per 5-ounce serving.
How Sweetness Changes the Count
Wines range from 0 to 220 grams of sugar per liter depending on the style. A bone-dry wine contributes less than 1 calorie per glass from sugar, making alcohol essentially the only calorie source. Sweet wines are a different story, adding anywhere from 21 to 72 sugar calories per glass on top of the alcohol calories.
To estimate sugar calories in a sweet wine, multiply the ounces by the residual sugar percentage, then multiply by 1.14. For a sweet wine with both alcohol and residual sugar, total calories can reach 139 or higher per glass. Late-harvest Rieslings, Moscato d’Asti, and dessert wines consistently land at the higher end of the calorie spectrum, even though they’re often served in smaller portions.
Serving Size Makes a Bigger Difference Than Varietal
The standard US wine pour is 5 ounces (about 148ml). In the UK, wines are served in regulated sizes of 125ml or 175ml by the glass, with 250ml also common. That 250ml glass holds nearly 70% more wine than the US standard, which means 70% more calories. If you pour generously at home, a kitchen “glass” of wine can easily hold 8 or 9 ounces, pushing a dry red past 200 calories.
Restaurant pours tend to be more consistent, but home pours are notoriously generous. If calorie counting matters to you, measuring your pour once or twice can recalibrate your sense of what 5 ounces actually looks like in your glass. It’s typically less wine than most people expect.
Non-Alcoholic and Low-Alcohol Wines
Dealcoholized wines (labeled as less than 0.5% ABV) contain significantly fewer calories than standard wine, but the range is wide. Most non-alcoholic wine brands average 70 to 90 calories per serving, with 14 to 25 grams of carbohydrates. The calorie savings come from removing alcohol, but the sugar content can actually be higher than in a dry conventional wine.
Some dealcoholized wines are much leaner. Certain brands produce sparkling options with as few as 10 calories per 5-ounce serving and just 2 grams of carbs. Others, particularly those that retain grape juice for body and flavor, sit closer to the 90-calorie mark. If you’re choosing non-alcoholic wine for calorie reasons, checking the nutrition label matters more than it does with conventional wine.
Why Wine Labels Don’t Show Calories
Unlike packaged food, wine in the US is not required to display calorie or nutrition information. The Alcohol and Tobacco Tax and Trade Bureau (TTB) regulates wine labels, and statements about nutrient content, serving facts, and sugar content are all classified as optional. Producers can include them voluntarily, but most don’t. This means you’ll rarely find a calorie count on the bottle itself, and estimating based on ABV and sweetness level remains the most practical approach for most people.
As a general rule: a standard 5-ounce glass of dry wine at 12 to 14% ABV contains 115 to 130 calories. Go sweeter and the count climbs. Go bigger on the pour and it climbs further. The varietal you choose matters far less than how full your glass is and how sweet the wine tastes.
