Root Beer and Caffeine

Question: Does root beer have caffeine in it?

Answer: I actually get asked this often. Most root beer doesn't have caffeine, but there are a few that do. Barq's and Rat Bastard are examples of root beer's that have caffeine. See Anthony's Root Beer Reviews for a review of over 100 different kinds of root beer, including information about whether or not a particular root beer has caffeine.
