Cream Soda is one of the soft drinks which is most reduced to its three main components: water, sugar, and caffiene. In the case of cream soda, the only other ingredients are 'Sodium Benzonate', caramel color, vanilla, citric acid (to make it taste bitter like soda), and 'natural and artificial flavors', the latter of which is just inserted to take into account anything like rat feces or oleander leaves which may have fallen in during processing.
