Q: What are the carbohydrate contents, if any, in Merlot, Chardonnay and Cabernet Sauvignon? -- Lyle Warner, Lubbock, Texas
A: Each particular wine will vary somewhat in nutritional content, but the USDA National Nutrient Database for Standard Reference, which you can find at nutrition.gov, lists general nutritional information for table wines. The average 5-ounce glass of Cabernet Sauvignon comes in at 3.82 grams of carbohydrates and Merlot at 3.69 grams. The database doesn't provide specific data for Chardonnay, but the average white table wine has 3.82 grams of carbs.
