Caffeinated Root Beers on the American Market
Not all root beer contains caffeine. While most brands do not include it, some key brands in the US market do. The most widely recognized caffeinated root beer is Barq's, but it is not the only option available.
Barq's Root Beer
Barq's is the most well-known exception to the caffeine-free rule. The slogan, "Barq's has bite!", is associated with its caffeine. A standard 12-ounce can of regular Barq's has approximately 22 mg of caffeine. This is only for the regular version. Diet Barq's and Barq's Zero Sugar are both caffeine-free. Barq's served in Coca-Cola Freestyle machines is also caffeine-free. Some regional versions may be caffeine-free to accommodate local customer preferences.
Sprecher Rev'd Up Root Beer
Craft brewers offer options for those who enjoy root beer with a kick. Sprecher produces a special version called "Rev'd Up Root Beer." While their traditional fire-brewed root beer is caffeine-free, the "Rev'd Up" version provides an extra energy boost. This version contains 93 mg of caffeine per 16 fl oz bottle.
Other Specialty and Energy Root Beers
Beyond the mainstream, niche and energy drink brands have produced caffeinated root beer flavors. Jolt Cola, known for its high caffeine content, offered a root beer flavor. Consumers exploring boutique or local soda shops may find other specialty brands that list caffeine. Always check the label to confirm a product's caffeine content.

Why Some Root Beers Include Caffeine
Root beer, in its traditional sense, is not a caffeinated beverage. The original recipes were based on roots and herbs, not the kola nut used in cola formulas. The inclusion of caffeine is an intentional choice by some manufacturers. Barq's has long relied on its unique caffeinated formula as part of its branding strategy.
How to Check for Caffeine
Checking the product label is essential. The presence of caffeine must be disclosed in the ingredient list. Most packaged foods and beverages with added caffeine are transparent. The word "caffeine" will appear in the ingredients. Check a manufacturer's official website for specific figures.
Conclusion
Brands like Barq's and Sprecher's Rev'd Up offer options for those who prefer caffeine. For the average consumer, brands like A&W and Mug are caffeine-free. Always check the ingredient list for mention of caffeine. The choice between caffeinated and non-caffeinated root beer boils down to preference.
