                                While most root beer brands on the market today are proudly caffeine-free, the notable exception is Barq's, which contains approximately 22 mg of caffeine per 12-ounce can. This might come as a surprise to many, as the beverage is not typically associated with the stimulating ingredient, unlike colas or energy drinks. The presence of caffeine in some versions means consumers must check labels carefully if they are monitoring their intake.
