Carbohydrate servings are based on roughly 15 g of carbohydrate per serving. Grapes contribute carbohydrates mainly as natural sugars, and a practical estimate is that about 15 grapes contain around 15 g of carbohydrate, so one serving of grapes is about 15 grapes. With 48 grapes, you’re estimating about 48 g of carbohydrate, which equals roughly three servings. Keep in mind grape size varies, so this is an approximation, but three is the best fit for typical grape sizes.
