what root beer has caffeine

Most root beer brands sold in North America are caffeine-free. However, there are some exceptions, and Barqs root beer is one of them. The regular variety of Barqs root beer contains around 22 mg of caffeine in each 12-ounce (355-ml) can, while the diet version is caffeine-free. Therefore, if you are trying to avoid caffeine, it is best to check the label or the products website to determine if it contains caffeine. Some popular brands of root beer without caffeine include A&W, Mug, Dads, Jones Soda, Kroger Big K, IBC, and Barqs Zero Sugar Root Beer.
