This article answers the question: how much caffeine is in Dr. Pepper?
What Is Dr. Pepper?
Dr. Pepper is a carbonated soft drink, aka “native Texan,” that originated in Waco, Texas in 1885 as America’s unique flavour (1).
Fun fact: the period from Dr. Pepper was dropped in the 1950s, yet both Dr and Dr. versions are used interchangeably to this day.
Dr. Pepper’s authentic blend of 23 unknown fruit flavours gives it its iconic, most-original, and misunderstood status. Besides the classic one, other types of Dr. Pepper variations include Cream Soda, Cream Soda Zero Sugar, Zero Sugar, Cherry, Cherry Zero Sugar, Cherry Vanilla, Diet, Diet Cherry Vanilla, Caffeine Free, Caffeine Free Diet, and Made With Real Sugar (2). However, only the classic and Diet flavours are available in Canada.
