A standard serving size of grapes is about 1/2 cup, which is roughly equivalent to a small handful - think a small fistful of grapes. But, if we're talking about red grapes specifically, the serving size is around 15-20 grapes, depending on their size. That's like, a small bunch of grapes, not a whole vine or anything!
Now, let's talk about why red grapes are so cool - they're like nature's candy, but without all the added sugar and artificial stuff. They're also super versatile, you can eat them as is, or use them to make wine, jam, or even grape juice. And, fun fact: red grapes are actually a type of berry, who knew?
