So, a wine’s average calories will also depend on the alcohol by volume (abv) of the wine. Specifically, alcohol contains around 7 calories per gram.
The other main source of calories in red wine is alcohol. Obviously, the fortified wine will have more calories than the Pinot Noir, which is why the best sweet red wines typically are served in smaller portions than dry red wine or white wine. A light-bodied red wine, like a Pinot Noir, may have around 3-4 grams of carbs in a 150mL pour, while a sweet, fortified wine can have up to 14 grams of calories per 150mL. So, the number of calories in your wine glass will depend partially on the amount of residual sugar. Sugar is a carbohydrate, which adds around 4 calories per gram to wine. However, the alcohol and the sugar that remains undigested by the yeast (residual sugar) serve as sources of calories in wine. Either way, it does not contribute calories. The carbon dioxide escapes in the case of still wines or is trapped as gas in the wine, in the case of sparkling wine. During the wine production process, yeasts break down the naturally occurring sugar in the grape juice and convert this sugar to alcohol and carbon dioxide. WHERE DO WINE CALORIES COME FROM?įirst, it is important to consider where wine calories actually come from.
CALORIES IN A BOTTLE OF RED WINE HOW TO
Let’s take a closer look at how to calculate the calories in a bottle of red wine. But just how many calories in your glass will depend on a series of parameters, most importantly the alcohol volume (abv) and sugar content in your red wine glass. Just like with everything else delicious, there are calories in a glass of wine.
Unfortunately, red wine calories do exist.
