Dr Pepper is a popular American carbonated soft drink, known for its unique blend of “23 flavors,” and is the oldest major soda brand in the United States. It was created by pharmacist Charles Alderton in Waco, Texas, in the 1880s and was first nationally introduced in 1904. Today, it is produced in the U.S. and Canada by Keurig Dr Pepper, and the brand has been expanded with various flavor variants, including cherry flavor.
