How much fructose or glucose is in grape juice?

Grape Juice typically contains around 15-20 grams of sugar per 100 milliliters, primarily consisting of fructose and glucose. The sugar composition can vary depending on the type of grapes used, but generally, fructose and glucose are present in roughly equal amounts. For example, a standard serving (about 240 ml) of grape juice may contain approximately 30-48 grams of total sugars, with about half being fructose and half glucose.
