A typical glass of white wine (about 5 ounces or 150 ml) contains approximately 100 to 120 calories. The exact calorie count depends on the type of white wine, its alcohol by volume (ABV), and its residual sugar content. Dry white wines usually have fewer calories (around 100-120), while sweeter white wines can have higher calorie content (up to 150-180 calories per glass) due to added sugar. For example, a 5 oz glass of white wine with about 11-13% ABV commonly falls into the 100-120 calorie range. Larger servings or sweeter varieties increase the calorie count accordingly.
