Dr Pepper is a unique blend of natural and artificial flavours
Dr Pepper is a carbonated soft drink created in the 1880s by American pharmacist Charles Alderton in Waco, Texas.

Dr Pepper has a unique flavor that is hard to describe, and the formula is a closely guarded trade secret. The company says that its secret formula is a mix of no less than 23 different flavors, and the recipe is split in half and kept in two separate Dallas banks, so no one can ever access the whole formula.

This rumor has been around since the 1930s, and it's speculated that it may be due to the drink's dark color, or because many people think it tastes similar to prune juice. It's also possible that the rumor started as an attempt by a competitor to discredit the drink, playing on the association of prunes with bowel movements.
While the exact ingredients of Dr Pepper remain a mystery, some people suspect that it contains flavors such as citrus, cinnamon, vanilla, denatured rum, and amaretto, which would suggest the use of almond or stone fruit extracts like cherries or apricots.
