A standard 5-ounce glass of white wine contains roughly 121 calories. That number shifts depending on the grape variety, sweetness level, and alcohol content, but most dry whites fall between 100 and 150 calories per glass.
Calories by White Wine Varietal
Not all white wines are created equal when it comes to calories. The two biggest factors are alcohol percentage and residual sugar, and both vary quite a bit across popular varietals.
Riesling tends to sit on the lower end, with a 5-ounce serving coming in around 100 to 125 calories. Rieslings are often lower in alcohol (some as low as 8 or 9%), which cuts the calorie count even when the wine has a touch of sweetness. Chardonnay and Sauvignon Blanc, which typically have higher alcohol levels, range from 120 to 150 calories per 5-ounce glass. Pinot Grigio falls in a similar range to other dry whites, generally landing around 120 calories.
The pattern is straightforward: higher alcohol means more calories, and sweeter wines add even more on top of that.
Why Alcohol Drives the Calorie Count
Alcohol itself is calorie-dense. Each gram of pure alcohol contains 7 calories, nearly double the 4 calories per gram in sugar or protein. In a typical glass of dry white wine, the vast majority of calories come from the alcohol rather than any leftover sugar.
This is why a wine labeled at 14% ABV will have noticeably more calories than one at 11%, even if both are bone-dry. A useful shortcut: for every percentage point of alcohol, a 5-ounce pour gains roughly 10 to 12 calories.
How Sweetness Adds Up
Dry white wines contain between 1 and 4 grams of residual sugar per liter, which adds negligible calories to your glass. Off-dry wines (like many Rieslings and Gewürztraminers) contain 5 to 20 grams per liter, enough to push the calorie count higher. Truly sweet dessert wines can exceed 30 grams of sugar per liter, and that sugar contributes meaningfully on top of the alcohol calories.
If you’re watching your intake, sticking with wines labeled “dry” keeps both sugar and calories lower. Bone-dry wines, with less than 1 gram of sugar per liter, have almost no sugar calories at all.
Pour Size Makes a Bigger Difference Than You Think
The standard restaurant pour is 5 ounces, and that’s the basis for most calorie counts you’ll see online. A 6-ounce pour, which is common at more generous restaurants, averages about 144 calories. That’s a 20% jump just from one extra ounce.
At home, the difference can be even larger. Most people don’t measure their pours, and a typical wine glass holds 12 to 20 ounces. Filling it halfway could easily mean 8 or 9 ounces of wine, putting you closer to 200 calories or more in what feels like “one glass.” If accuracy matters to you, pouring into a measuring cup once or twice will calibrate your eye for what 5 ounces actually looks like. It’s less than most people expect.
White Wine vs. Red Wine
White wine is slightly lower in calories than red, but the gap is small. A 5-ounce glass of red wine averages about 125 calories compared to 121 for white. The difference comes down to red wines generally having a bit more alcohol and slightly more residual compounds from the grape skins. In practical terms, choosing white over red saves you fewer than 5 calories per glass, so picking based on calorie count alone isn’t especially useful.
Where white wine does pull ahead more clearly is against cocktails and mixed drinks. A margarita or piña colada can easily run 300 to 500 calories. Beer varies widely, but a standard 12-ounce craft beer often sits around 180 to 250 calories. A glass of dry white wine is one of the lower-calorie options if you’re choosing an alcoholic drink.
