Question: How Many Calories in Red Wine?
How many calories are in a glass of red wine? Well, that depends somewhat on the person pouring the glass of red wine. A typical restaurant pour of red wine is 5 ounces, yet most of the trendy diets that allow wine, recommend 4 ounces of red wine as a standard serving size.
Answer: When it comes to the number of calories in a glass of red wine, you can figure approximately 25 calories per ounce of red wine. So your glass of red wine at a typical restaurant tops out at 125 calories. While the standard "diet-friendly" glass of red wine only weighs in at 100 calories per 4 ounce, not bad!
