A Surprising Exception to the Rule: Barq's Root Beer
When people think of root beer, they almost always assume it is a caffeine-free beverage. This is largely true, as the traditional recipe and most major brands, such as A&W, Mug, and Dad's, contain no caffeine. The most significant and nationally distributed exception to this rule is Barq's Famous Olde Tyme Root Beer. For decades, its signature 'bite' has set it apart, and that unique quality comes from the addition of caffeine.
Regular Barq's contains approximately 22 milligrams of caffeine per 12-ounce can. While this is a modest amount compared to coffee (which can have over 90 mg in an 8-ounce cup), it is enough to make a difference for those who are sensitive to caffeine or are actively trying to avoid it. The inclusion of caffeine dates back to the brand's early history, possibly as a way to distinguish itself from competitors in the market.
Other Caffeinated Root Beer Options
While Barq's is the most prominent example, it is not the only caffeinated root beer on the market. Some craft brewers and specialty companies offer caffeinated versions to cater to consumers looking for an extra kick. For instance, Sprecher offers a product called "Rev'd Up Root Beer," which is their classic formula with added caffeine. These products are typically clearly marked to indicate their higher energy content. For anyone seeking to avoid caffeine, it is always best practice to check the ingredients label, especially for lesser-known or craft root beer brands.
Why Do Some Root Beers Have Caffeine?
Root beer was originally a form of 'small beer' brewed from herbs, roots, and berries, and was naturally caffeine-free. When it was commercialized, brands were free to create their own formulas. Barq's, first bottled in 1898, used a sarsaparilla-based recipe and added caffeine. This intentional addition gave the brand its famous 'bite' and differentiated it from rivals like Hires. Later, the Coca-Cola company acquired Barq's and maintained the caffeinated formula for its regular version.
Caffeine-Free Versions and Formulations
For those who love the flavor of Barq's but want to avoid caffeine, the brand offers alternatives. The Diet Barq's Root Beer is explicitly caffeine-free. Additionally, the Barq's root beer served from Coca-Cola Freestyle machines is also caffeine-free. These variations provide a convenient option for consumers who must limit their caffeine intake but want to enjoy the flavor. Other brands, such as A&W, Mug, Dad's, Jones Soda, and Stewart's, have always maintained caffeine-free recipes, making them safe choices for the caffeine-conscious consumer.

Caffeine Content in Context
It's important to understand the caffeine content in Barq's relative to other popular drinks. While 22 mg is low compared to a cup of coffee, it is not an insignificant amount, especially if multiple cans are consumed. In comparison, a 12-ounce can of Coca-Cola has around 34 mg of caffeine, while Diet Coke has about 46 mg. A typical energy drink can have 70-150 mg per 12-ounce serving. Barq's caffeine level is closer to a weak cup of tea. For a consumer, this means that while a single can is unlikely to cause a significant jolt, it could affect those with high sensitivity or interfere with sleep if consumed late in the day. Knowing the content allows for informed consumption decisions, which is particularly relevant for parents buying for their children or individuals with specific health concerns.
Conclusion
While most root beer brands on the market are caffeine-free, it's a mistake to assume they all are. The most well-known exception is regular Barq's Root Beer, which contains approximately 22 mg of caffeine per 12-ounce can. Other niche or craft brands, like Sprecher's 'Rev'd Up' variety, also include caffeine. However, many popular brands such as A&W and Mug remain caffeine-free, and most brands also offer a diet or zero-sugar, caffeine-free version. Checking the nutritional label is the most reliable way to confirm the caffeine content and ensure your beverage choice aligns with your dietary needs.
