Question: Does root beer have caffeine?
Answer: The amount of caffeine in root beer depends on the brand that you buy. Generally, root beer does not contain caffeine. Barq’s (excluding diet) is the only major root beer that has caffeine. Additionally, there are a few smaller root beer brands that have caffeine. Two examples are Rat Bastard Root Beer (caffeine unknown) and Bawls Guarana Root Beer (64 mg per 10 fl oz/102 mg per 16 fl oz).[the_ad id=”49754″]
