Most Root Beers Are Naturally Caffeine-Free
For many years, root beer has been a favored beverage for its creamy, sweet, and spiced flavor profile. Unlike colas that traditionally include extracts from the caffeine-rich kola nut, root beer's origins trace back to medicinal and brewed teas made from roots and herbs like sassafras, licorice, and wintergreen, which do not naturally contain caffeine. Modern commercial brands typically use artificial flavors, but they continue this caffeine-free tradition.
This means that if you grab a bottle of A&W, Mug, or Dad's root beer, you can expect a refreshing, non-caffeinated experience. However, there are exceptions to the rule, with some manufacturers choosing to add caffeine for a unique "bite" or marketing edge. This can sometimes lead to confusion for consumers, especially those monitoring their caffeine intake.
The Caffeinated Exception: Barq's Root Beer
When it comes to caffeinated root beer, Barq's is the most well-known and widely distributed brand. It has long been distinguished by its slogan, "Barq's has bite!", which refers to its sharper flavor profile and its inclusion of caffeine.
A 12-ounce can of regular Barq's Root Beer contains approximately 22 milligrams of caffeine. This is a relatively modest amount compared to other popular sodas or coffee. However, it is a significant factor for anyone seeking a stimulant-free beverage. It's crucial to note that not all Barq's products contain caffeine. Specifically, Barq's Diet Root Beer and Barq's Root Beer dispensed from Coca-Cola Freestyle machines are caffeine-free.
Other less common or craft brands may also add caffeine. One such example is Sprecher's "Rev'd Up Root Beer," a specialty variant that is explicitly marketed as having an added caffeine kick.
Caffeine-Free Root Beer Brands
For those who prefer their root beer without any caffeine, the good news is that the market is full of options. Most brands stick to the traditional, stimulant-free recipe. Here are some of the most popular and readily available caffeine-free root beers:
- A&W Root Beer: A classic American favorite, A&W Root Beer has been caffeine-free for over a century and is made with aged vanilla for its signature creamy flavor.
- Mug Root Beer: Another widely available choice, Mug is completely caffeine-free across both its regular and zero-sugar varieties.
- Dad's Root Beer: Founded in Chicago in the 1930s, Dad's offers an old-fashioned flavor and is entirely caffeine-free.

- IBC Root Beer: An old-fashioned soda brand, IBC provides a smooth, caffeine-free root beer in a classic glass bottle.
- Jones Soda Root Beer: Known for its unique flavors and packaging, Jones Soda's root beer is also caffeine-free.

How to Check for Caffeine in Any Root Beer
If you're unsure about a particular brand, the best course of action is always to check the ingredient label. In the United States, manufacturers are required to list caffeine as an ingredient if it has been added to the product. It's typically listed alongside the artificial and natural flavors towards the end of the ingredient list. Pay special attention to diet or sugar-free versions, as these may have a different caffeine profile than their regular counterparts. Also, be mindful of how the soda is dispensed; as with Barq's, fountain drinks can sometimes differ from their bottled versions.
Conclusion
While most root beers have no caffeine, the important takeaway is that exceptions exist. Regular Barq's is the most prominent caffeinated root beer brand available nationally, offering a small but noticeable stimulant boost. In contrast, mainstream brands like A&W, Mug, and Dad's remain reliably caffeine-free. For anyone monitoring their caffeine intake, checking the ingredient label is a foolproof way to ensure your beverage choice aligns with your preferences. This allows you to enjoy the rich, creamy flavor of root beer, whether you want the extra kick or a completely calm and relaxing sip.
