On average, Beer has a lower calorie count per ounce than Wine. However, usually people who drink beer, often drink more, since 12 ounces are in a bottle, while a typical wine glass may be filled with only 6 ounces of wine. So while wine typically has more calories than beer per ounce, a wine drinker will often drink less calories than if they were to a drink beer, for the simple fact that they will usually consume fewer fluid ounces.
