Although all dry wines have similar calorie counts, they differ somewhat by variety. In general, red wines like cabernet, tend to have slightly more calories per serving than white wines, have slightly more alcohol, as well. For good health and to minimize calorie intake, women should limit wine intake to one or fewer glasses per day, while men should have no more than two glasses per day.
A 5-ounce glass of either cabernet sauvignon or cabernet franc contains about 122 calories. Most of those calories come from the alcohol, which contains 7 calories per gram. Alcohol calories provide energy, but do not have nutritional value like calories from carbohydrates, fat and protein. However, any type of calorie can contribute to weight gain, if you consume more calories than you burn through activities.
