The Answer:

The number of calories in red wine and white wine does differ slightly; typically, four ounces of white wine have about five calories less than red wine. With that said, the number of calories in different varieties of wine differ far more; the higher the alcohol content, the higher the calorie count.

We found a chart listing calories in wine varieties, and you can use the USDA National Nutrient Database to search for the nutritional and caloric information for all sorts of wines (and other drinks and foods). In the latter case, the "energy in kcal" is the calorie count.
