How many calories are there in a glass of wine?
Just because wine contains no fat or cholesterol, don't get the idea that you can drink a lot of it without showing the results on your waistline.
The exact calorie content of wine varies depending on both its alcohol and sugar content, so a strong, sweet wine like Port has a much higher calorie load than a dry table wine of normal strength.
But you can assume that your 5-ounce glass of dry red or white table wine is likely to have 100 to 125 calories, while a rich dessert wine could go up to 150 calories or more for a smaller 3-ounce glass.
