Glycemic index of wine
The glycemic index of wine is about 15. Dry wine has a low glycemic index. Most of the grape sugar has fermented into alcohol. The small residual carbs combined with the alcohol's effect on gluconeogenesis keeps the blood sugar impact low for most people.
For diabetes
A 5-oz glass of dry red or white wine has about 3 to 4g of carbs, which is very modest. The bigger concern for people with diabetes is alcohol's suppression of liver gluconeogenesis, which can cause delayed hypoglycemia hours after drinking. Eating when you drink wine reduces that risk. Sweet and dessert wines can have 10 to 30g of carbs per glass. See the diabetes carb-counting guide.
Keto and low carb
A 5-oz glass of dry red or white wine has about 4g of net carbs, which fits comfortably in most keto plans. Brut champagne and sparkling wines run 1 to 3g per glass. Sweet dessert wines can have 15 to 30g per serving and are not keto-compatible.
Good to know
Wine carbs come from residual grape sugar left after fermentation. Dry wines have been fermented until most sugar is converted to alcohol. Residual sugar is measured in grams per liter: a bone-dry wine has under 4g/L, while a sweet wine like Riesling Spatlese can have 40 to 80g/L. White wines and red wines are similar in carb content gram for gram. Rose wine sits in the same range. Port, sherry, and dessert wines are fermentation-stopped, which leaves much more residual sugar.
