Alcoholic beverages are not required to carry nutrition facts labels. The calorie content of alcoholic beverages is often a mystery to many people. If you are trying to count calories, accounting for your glass of wine at dinner can be a struggle. Caloric content of wine varies depending on the type of grape used, how long the wine is fermented, and the amount of sugar added to the product. To help eliminate some of the mystery, the USDA has come up with an average caloric content for various types of wine.
According to the USDA, an average red table wine contains 125 calories for every 5 fl oz, or approximately 625 calories in a bottle. Syrah, Merlot and Cabernet Sauvignon have 122 calories in 5 fl oz, or 610 calories per bottle. A Pinot Noir has slightly fewer calories -- 121 calories in 5 fl oz, or 605 calories per bottle.
According to the USDA, an average white table wine has 121 calories in 5 fl oz, or 605 calories per bottle. Riesling has slightly fewer than average -- 118 calories in 5 fl oz, or 590 calories per bottle. If you drink Sauvignon Blanc, you will get 119 calories in 5 fl oz, or 595 calories in a bottle. Chardonnay has slightly more -- 123 calories in 5 fl oz, or 615 calories per bottle.
