Wine Folley answers the question, “How many carbohydrates are in a glass of wine?”

A glass of wine has 0-4 grams of net carbs*

*This is based on a standard serving of 5 ounces with up to 20 g/L of residual sugar (which is noticeably sweet). Dry wines typically have less than 2 g/L RS and ~0 carbs.
