Fanta Cream Soda

I just had one of those “everything I ever thought was truth is now a lie” moments. This is soda mousse aka Canadian cream soda. From the can I expected it to be red, like the Crush version of it. Instead it is clear like most cream sodas. There is nothing mind shattering there. That came when I saw that it was made with real grapes. Does cream soda normally have some sort of grape base that I have been completely ignorant of my whole life? I don't think that is does, and my tertiary search online came up with nothing. That leads me to a follow up question; why does this have grape juice in it? Until I noticed that it had grape juice in it I thought it tasted similarly to the Crush cream soda; fairly standard with a slight berry flavor to it. Now I'm second guessing that. It tastes weird to me knowing that there is grape juice involved. I feel like my taste buds are trying their hardest to search out a grape flavor. Do I actually taste it or am I imagining it? I can't say for sure, and there is no one around for me to have them try it. I can say I enjoy the pop. It's hard to go wrong with cream soda, especially one that is slightly unusual.
