To answer that extremely important and often overlooked question you need to first know the calories inherent in wine. A 4-oz glass of wine ranges from about 80 to 100 calories. Always keep that in mind. Secondly, lighter wines have fewer calories than heavier wines.
After all, it would seem strange if a Cabernet Sauvignon was less fattening than a Chardonnay or even a Gamay or a typical Shiraz.
Thirdly, and this is where it gets tricky, some wines are higher in carbohydrates than others due to their residual sugars. For example, a dry Sauvignon Blanc may have two grams of carbohydrate whereas a very sweet dessert wine could have as much as 12 grams. The alcohol content is usually the giveaway. Wines with higher alcohol content typically are more fattening.
Lastly, note that wine itself is fat-free and contains no cholesterol. So if you have high cholesterol you needn’t worry about wine making things worse. But then again, if you have high cholesterol you should do exactly what the doctor says, and not follow what this blog tells you!
As you go about drinking wine, always remember that it is important to drink in moderation. Even though wine has numerous health benefits (and is not very fattening) drinking in excess is always bad.
