The level of Vitamin C in grapes is actually quite significant, with around 3.7 mg for every 92 grams or 10.8 mg for every 100 grams. The amount of vitamin c in the grapes depends on what type they are and whether or not they are organic.

When it comes to getting the most out of the grapes you eat in terms of overall nutrition, organic is always better.

Grapes that appear to have a whitish color on the outside have been treated with pesticide and it is important to wash them thoroughly before eating them, as it is the safest thing you can do.
