Energy drinks contain very high levels of caffeine. A single 5-hour Energy shot contains almost as much caffeine as four 12-oz. cans of Mountain Dew. While many people will tell you that Mountain Dew has the most caffeine of any soft drink, that is incorrect. A 12-ounce (355 ml) can of Mountain Dew has about 55 mg of caffeine, compared to 72 mg in the same amount of Jolt Cola, 69 mg for Pepsi MAX, 63 to 69 mg for Sun Drop, or 59 mg for Sugar-free Mr. Pibb.
Barq's Root Beer is one of the few types of root beer that contains caffeine. However, the company does offer a caffeine-free variety for consumers to purchase. Continue Reading. According to the Center for Science in the Public Interest, Barq's Root Beer has approximately 23 mg of caffeine per 12-ounce serving. The official Food and Drug Administration (FDA) limit for caffeine in soft drinks is 71 mg of caffeine per 12-ounce serving, making Barq's well below the limit. In comparison, a cup of strongly brewed coffee typically has between 75 and 100 mg of caffeine per serving, which is far more than Barq's.
