Dr Pepper 23 Flavors Explained: List of Ingredients, History, and Rankings
By Alexander Ross
For more than half a century, schoolyards, diners, and internet forums have circulated a stubborn rumor: Dr Pepper relies on prune juice as its secret thickening base. The rumor became so prevalent that the brand added a permanent disclaimer to its corporate FAQ, explicitly confirming that Dr Pepper contains zero prune juice or concentrated dried plum paste.
The myth traces back to the late 1930s. Rival delivery drivers used the claim to imply the beverage served as a laxative, attempting to steer lunch counters toward standard colas. Food scientists point out that while the compound benzaldehyde, which provides stone-fruit and almond nuances, is naturally present in plums, prunes, and cherries, pure prune juice would cause carbonated sodas to separate, spoil rapidly on ambient shelves, and turn cloudy. The actual mouthfeel comes from high-fructose corn syrup, citric acid, and phosphoric acid balancing the botanical extracts.
