Root Beer: The Mostly Caffeine-Free Soda
Most people assume all sodas have caffeine, but that is simply not true for the majority of root beer brands. Traditional root beer was never meant to be a caffeinated beverage. Its origins trace back to a drink brewed from roots, herbs, and bark, with its characteristic flavor originally coming from sassafras root. Modern root beer retains these herbal flavor profiles, using artificial sassafras flavoring since the FDA banned the original ingredient, safrole, in 1960.
The Notable Exception: Barq's Root Beer
While brands like A&W, Mug, and Dad's are proudly caffeine-free, the most famous exception is Barq's. Its slogan, "Barq's has bite!," famously referred to its caffeine content. A standard 12-ounce can of regular Barq's contains approximately 22 mg of caffeine. This is an intentional addition, though the brand’s diet version remains caffeine-free. For reference, 22 mg is less than a can of Coke, which contains 34-38 mg. Other, less common brands like Sprecher's 'Rev'd Up' root beer also contain added caffeine.
Coffee: The Undisputed Caffeine Champion
Coffee's caffeine content is a product of its natural composition and preparation. The level of caffeine can vary significantly based on the bean type, roast, and brewing method.
Factors Influencing Coffee's Caffeine Content
- Coffee Bean Variety: There are two main types of coffee beans: Arabica and Robusta. Arabica beans are prized for their flavor but have lower caffeine (1.1-1.7%). Robusta beans are more bitter but have significantly higher caffeine (2.0-4.5%).
- Roast Level: Darker roasts lose a tiny amount of caffeine in the roasting process, but the difference is minimal and often overshadowed by other factors like the brewing method. Many people perceive dark roasts as stronger because of their flavor profile, not their caffeine.
- Brewing Method: The extraction method has a major impact. An 8-ounce cup of filter-brewed coffee typically contains around 95 mg of caffeine. In contrast, a single 1-ounce shot of espresso can have around 63 mg, but most espresso-based drinks use multiple shots. Even decaf coffee is not entirely caffeine-free, containing 2-5 mg per cup.
Caffeine Comparison: Root Beer vs. Coffee
To put the difference in perspective, here is a direct comparison of caffeine content in common beverage servings.
| Beverage | Serving Size | Approximate Caffeine Content |
|---|---|---|
| Brewed Coffee | 8 oz (240 ml) | 95 mg |
| Barq's Root Beer | 12 oz (355 ml) | 22 mg |
| Diet Barq's Root Beer | 12 oz (355 ml) | 0 mg |
| A&W Root Beer | 12 oz (355 ml) | 0 mg |
| Decaf Coffee | 8 oz (240 ml) | 2-5 mg |
| Espresso | 1 oz shot | 63 mg |
Making an Informed Decision
If you are mindful of your caffeine consumption, the choice between root beer and coffee is relatively straightforward. For a caffeine-free experience, a standard root beer is a safe and reliable option. If you crave a modest stimulant kick, a can of Barq's provides a significantly lower dose than most coffee drinks. Anyone seeking a substantial caffeine boost for energy or alertness will find that coffee offers far more potency per serving.
It is important to remember that the Food and Drug Administration (FDA) suggests that up to 400 mg of caffeine per day is generally safe for healthy adults. However, personal tolerance varies, and it is wise to pay attention to your own body's response. For individuals with medical conditions or sensitivities to caffeine, reading labels is crucial, as some root beer manufacturers have intentionally added the stimulant.
Conclusion: Coffee Provides the Real Kick
Ultimately, when comparing caffeine content, coffee and root beer are not in the same league. Coffee is a natural source of a powerful stimulant, with levels that can range from moderate to very high depending on the brew. Conversely, most root beer contains zero caffeine, and the few caffeinated varieties offer a very minimal amount. Therefore, to the question "Does root beer have more caffeine than coffee?," the answer is a definitive and resounding no. For anyone looking to reduce or avoid caffeine, traditional root beer is a much safer bet than even decaf coffee, which contains trace amounts.
