Root Beer: The Caffeinated Exceptions
Traditional root beer recipes, which historically used sassafras and other roots, did not naturally contain caffeine. Modern commercial versions of the soft drink are based on these traditional formulas but are almost universally produced without caffeine. This makes it a popular choice for those seeking a non-caffeinated soda option. However, there are a handful of notable exceptions on the market, with the most famous being regular Barq's Root Beer.
The presence of caffeine is an intentional addition by manufacturers, often to distinguish their product with a more pronounced 'bite' or 'spark,' as Barq's famously advertises. For most brands, if the product is caffeinated, it will be explicitly listed on the ingredients label, as the Food and Drug Administration requires for foods with added caffeine. This is a crucial detail for consumers who need to manage their caffeine consumption for health or personal reasons. It is always wise to read the label of any soft drink, as even varieties of the same brand can differ in caffeine content, as seen with Barq's regular versus its diet version.
The Most Famous Caffeinated Root Beer: Barq's
Among the mass-market options, regular Barq's Root Beer is the most well-known caffeinated root beer. A 12-ounce can contains approximately 22 mg of caffeine, a relatively small amount when compared to a similar-sized serving of coffee (around 96 mg) or many energy drinks. This caffeine content gives Barq's its distinctive 'bite' and sets it apart from many other brands that pride themselves on being caffeine-free. Interestingly, Barq's Diet or Zero Sugar Root Beer does not contain caffeine, highlighting the importance of checking the specific product label.
Other Caffeinated Root Beer Brands
While Barq's is the most common example, it is not the only caffeinated root beer. Other brands, often specialty or craft sodas, also include caffeine in some of their varieties. For instance, Sprecher Brewery offers a caffeinated version of its classic brew, called Rev'd Up Root Beer. Jolt Root Beer is another brand historically known for its high caffeine content, though availability can vary. These less common brands are important for anyone exploring the full spectrum of caffeinated root beer options.

Conclusion
When asking which root beers have caffeine in them, the answer is that while most mainstream brands are caffeine-free, a few key exceptions exist. Regular Barq's is the most prominent caffeinated option, though other craft varieties like Sprecher's Rev'd Up also offer a stimulant kick. The best practice for anyone concerned about their caffeine intake is to always check the ingredient label before purchasing. For those seeking a delicious beverage without the stimulant, major brands like A&W, Mug, and Dad's remain reliable caffeine-free choices.
