How to Determine Calorie Content of Wine. Food and beverage companies list caloric and carbohydrate information on labels for consumers. Interestingly, many alcohol manufacturers choose to omit the calorie content of wine. Today, consumers are calorie conscious and are calculating calories for themselves. Determine the calorie content of wine by following these steps.
Have a piece of paper handy to jot down some calculations.
List the percent of alcohol contained in the wine. Alcohol content is usually written as a percentage on the wine label.
Determine how many ounces are going to be calculated and write that number down.
Multiply 1.6 times the wine percentage by the number of ounces.
Review this example. Determine the calorie content of a 5 ounce glass of wine that contains 10 percent alcohol. The equation becomes: 5 ounces x 10 percent x 1.6 = calories. Therefore the calculation is 5 x 10 x 1.6 equals 80 calories in this particular glass of wine.
Notice that wines with a higher alcohol content will contain more calories. However, the upside is that even on a calorie conscious regimen, there's still room to have a glass wine every now and then.
