Reply To: Grape Juice Light

I always thought that the reason bottled grape juice tastes much sweeter than freshly squeezed grapes is because they add concentrated grape juice (this rather than sugar so that they can still call it 100% grape). Can anyone here who knows more about it either confirm or deny this? If it is true then perhaps light grape juice is just plain juice without the added concentrate. (Anyone who has eaten a cupful of fresh grapes can immediately feel that it is much lighter and less sweet than a cupful of regular grape juice.)
