“you cannot tell anyone what Dr Pepper tastes like because it’s so different. It’s not an apple; it’s not an orange; it’s not a strawberry; it’s not a root beer; it’s not even a cola.” Cola, after all, is derived from kola nuts and vanilla, two real-world flavors. Sprite has that lemon-lime taste. Purple soda is ostensibly grape-flavored. But Dr Pepper has no natural-world analogue.
