How many calories are in wine?

­Wine can be a great addition to a nice meal, a friendly gathering or a quiet night at home. There are wines ­that are produced specifically to enhance and bring out the flavor of your favorite foods. And there's scientific research that suggests there are medical benefits to consuming moderated amounts of wine. But just because drinking wine could be healthy doesn't mean you have a free pass to indulge -- in particular if you're dieting. The calories in beverages, especi­ally those containing alcohol, can really add up.

Here's a list of wine categories with an estimate as to how many calories you can expect to find in one bottle, 750 ml (25.4 fluid ounces), of wine unless otherwise marked:

­Wines such as Port, Sherry and Vermouth are the highest in calorie count. But as a rule, when served properly, these varieties will be ­served in smaller glasses than a standard wine glass [source: Stevens]. With other wines, the actual amount of calories you consume really depends on the size of the glass you're using, which will dictate the actual serving size. As stated above, a typical bottle holds a little more than 25 fluid ounces of wine. So, if you are using 4-ounce size glasses, one bottle will contain six servings. If you're using larger glasses, such as 6-ounce size glasses, one bottle will contain four servings. With this in mind, you can then calculate your calories per serving -- for example, a glass of red wine could be either 100 or 125 calories.

If you're concerned with the nutritional values associated with wine or you're on a diet, you might want to look beyond the calorie count. Consider this -- a 5-ounce serving of champagne contains approximately 40 milligrams of sodium and 2.7 grams of carbohydrates.
