The term 'Dr Pepper Alternative' refers to three different soft drinks: Cola (4 letters), MrPibb (6 letters), and RC Cola (6 letters). Cola is a type of carbonated soft drink that is flavored with a blend of spices, including nutmeg, cinnamon, and vanilla. MrPibb is a variation of the original Dr Pepper formula, created by the Coca-Cola Company in the 1970s. RC Cola is a brand of cola created by the Royal Crown Company in 1905. All three of these drinks are popular alternatives to Dr Pepper.
