dude not smort. the can says: Natural and artificial flavors. No one but those three people know the true flavors and proportions to each and every organic and inorganic ingredient that makes Coke taste the way it does. I am smorter to know that you don't mess with someone like that.
Wouldn't the natural flavour be that of the kola nut? Supposedly Coca Cola doesn't use the kola nut anymore, but then: unless it's coming from some other natural resource, it wouldn't be natural flavour, would it?
