The number of calories in white wine, depend on who is pouring the wine. The standard volume of wine used in most nutritional charts is based on a 4 ounce pour. Most white wines run along 25 calories per ounce, with some of the sweet or dessert wines, with higher levels of residual sugar, topping in a bit higher.
Keep in mind that most wine enthusiasts are more generous with their wine pours, and the average glass of wine poured by the consumer rocks out at 5-6 ounces. It's not likely that many wine lovers whip out their measuring cup and notch their glass at the half cup mark, before they pour into their wine glass - I think many would be surprised at just what 4 ounces of wine really looks like!
Try not to be too consumed with the numbers, it'll just get in the way of truly enjoying that glass of wine. Wine is truly meant to be savored and enjoyed by those with a love of the grape.
Look at it from a different angle if your watching calories and carbs. Wine enhances your well being and if need be, cut back on the bread or serving portion of your next meal. Enjoy what's in the wine glass in front of you. Life is too short to not fully enjoy a glass of wine now and then with friends, loved ones, or the wonderful simple pleasure of keeping it all to yourself.
It is really just that simple, seriously! Keeping it seriously simple.
Stress less and enjoy!
