I dont know what it is about grape soda, but ever since I was young, if I drank grape soda I could throw up on cue. I dont know what it is about grape soda but when I drink it I can vomit with little effort.
Grape flavoring are awesome....... love grape sweet tarts. I do agree however that grapes the fruit taste nothing like flavored things.
All that comes to mind is Rob Cordrey on Harold and kumar escape from Guantanamo pouring out the grape soda in front of the black guy to get him to talk.
