I used to love Dr. Pepper until someone told me this now I can't drink it. I don't know if it's true, but it sure tastes like it.

so i've heard, yes.

A little history- The drink originated no later than December of 1885, in Waco, Texas, and introduced nationally in the United States at the 1904 Louisiana Purchase Exposition. It was created by a German pharmacist named Charles Alderton, working with the proprietor of Morrison's Old Corner Drug Store & soda fountain, Wade Morrison. Visiting patrons at Morrison's soda fountain would order what was then called a "Waco." It is believed by some that the drink was named after Morrison's former employer in Texas, but this has been disputed by the Dr Pepper company itself, which claims Morrison once lived in Wythe County, Virginia near a Dr. Charles T. Pepper, and may have been romantically involved with Pepper's daughter. The name is also at times referred to as a play on words- "pep", to pep one up via the drink's magical ability. Dr Pepper is not marketed as a cola per se, like competiors RC, Coca-cola, and Pepsi. Dr Pepper's flavor was supposedly derived from a mixture of soda fountain flavors popular when the drink was first mixed. A partial list of these flavors can be seen at the Texas bottling plant, though the full list is a closely guarded secret. The original formula, which can still be ordered in certain locations and at dublindrpepper.com , is made with cane sugar, and is rumored to be highly superior to the mass-market version using corn syrup. It is believed cherry and vanilla are part of the ingredients. Some suggest Guarana. Dr Pepper claims it does not, and never has, contained prune juice. Many fans believe otherwise. and some even swear that, many moons ago, when the drink was still fairly unknown, the bottle contained prune juice on the label. Fans of the drink also claim that bottled Dr. Pepper is far superior to canned Dr. Pepper. Other suggestions? Including the above- Amaretto, apricot, allspice, almond, burdock root, burnt rum, black licorice, bitters (such as Angostura brand), blackberry, birch bark, clove, coriander, carrot, caramel, cola nuts, caramel, chocolate, cherry, cardomom, dandilion root, dog grass, fennel, grapefruit, ginger, guaiacum chips, grape, guarana, hops, juniper, nutmeg, lemon, lime, mace, molasses, orange, peach, prune (although denied), plum, prickly ash bark, pepper, pipsissewa, raspberry, rhubarb, rosemary, root beer, sassafras root, spikenard, sarspirilla root, spicewood, star anise, tomato, vanilla, wintergreen, wild cherry bark, and yellow dock. Anyone think anything else? Oh, and if you're really a fanatic, here's a fun website to poke around... http://www.freenewyork.net/dpfaq.html

Royal Crown Cola, RC, has prune juice as a natural flavor. Not sure about Dr. Pepper. Its a guarded secret.
