The Traditional Roots: A Caffeine-Free History
Root beer's history is deeply intertwined with North American indigenous peoples and European colonists who adapted herbal tea recipes for their medicinal and social properties. The original root beer was a 'small beer,' a low-alcohol brew made from fermenting a concoction of roots, bark, and herbs. Ingredients varied widely, drawing from local flora, including sarsaparilla, ginger, licorice root, and, most famously, sassafras. None of these traditional, foundational ingredients naturally contain caffeine. Therefore, if you were drinking an authentic, historically-accurate root beer, you would not have consumed any caffeine.
The Commercial Revolution of a Temperance Drink
The commercialization of root beer took off in the late 19th century, led by Philadelphia pharmacist Charles Hires. A Quaker, Hires actively promoted his version of the drink as a non-alcoholic alternative to beer during the temperance movement. He initially marketed it as a concentrated powder or liquid extract for home brewing, which was then mixed with water. Hires' non-alcoholic formula became a national sensation, establishing root beer's reputation as a family-friendly soda. For decades, commercial root beer remained true to its caffeine-free roots, with the bubbly carbonation providing the 'kick' rather than a stimulant.
The Sassafras Saga and the FDA Ban
In the 1960s, a pivotal moment occurred that forever changed the composition of commercial root beer. The U.S. Food and Drug Administration (FDA) banned the use of sassafras as a flavoring agent due to concerns over safrole, a compound naturally found in sassafras root. Studies showed that high doses of safrole could cause cancer and liver damage in rats.
This ban forced manufacturers to innovate, and they responded in a few ways:
- Safrole-free extract: Some companies started using sassafras extract from which the safrole had been removed, allowing them to maintain the traditional flavor profile.
- Artificial flavoring: Many producers switched to a blend of artificial and natural flavors that mimicked the taste of sassafras.
- Sarsaparilla and other bases: Some recipes, like the one used by Barq's, were originally based on sarsaparilla rather than sassafras.
This change demonstrates a crucial distinction between old-world recipes and the modern industrial beverage, affecting both flavor and safety. For nutrition-conscious consumers, this highlights the importance of scrutinizing ingredient lists.
Modern Root Beer: The Caffeine and Sugar Impact on Your Diet
The question of caffeine in root beer only became relevant with modern, mass-produced versions. While most major brands, such as A&W, Mug, and Sprecher, continue the caffeine-free tradition, one notable exception is Barq's.
Barq's Root Beer contains approximately 22 mg of caffeine per 12-ounce can. The reason for this inclusion is not entirely clear, but it is believed to have been a way to differentiate the brand in the competitive market. Barq's caffeine content is relatively low compared to a cup of coffee (around 95 mg) but similar to a cup of brewed black tea. This is a critical point for individuals sensitive to caffeine, such as children, pregnant women, or those with certain heart conditions. It's a reminder to always check the label, as not all root beers are created equal.
From a nutrition diet perspective, the primary concern with all regular root beers today, whether caffeinated or not, is their high sugar content. Like most sodas, a single serving can contain significant amounts of sugar, often in the form of high-fructose corn syrup. This contributes to excess calorie intake, which is associated with weight gain, dental problems, and an increased risk of type 2 diabetes.
Comparing Traditional and Modern Root Beer
| Feature | Traditional Root Beer (Pre-1960) | Modern Root Beer (Regular) | Modern Root Beer (Diet) |
|---|---|---|---|
| Caffeine | No (naturally caffeine-free) | No (mostly, except brands like Barq's) | No (Barq's diet is caffeine-free) |
| Primary Flavoring | Sassafras (safrole-containing) | Artificial sassafras flavor or safrole-free extract | Artificial sassafras flavor or safrole-free extract |
| Sweetener | Molasses, sugar, or honey | High-fructose corn syrup or sugar | Artificial sweeteners (aspartame, sucralose) |
| Carbonation Method | Fermentation (low alcohol) | Added carbonated water | Added carbonated water |
| Nutritional Profile | Variable (often medicinal) | High in sugar and calories | Sugar-free and zero calories, but relies on artificial sweeteners |
| Digestive Effect | Varies, can have laxative effect | Can cause gas and bloating from carbonation and sugar | Can cause diarrhea in sensitive individuals due to sugar alcohols |
The Modern Root Beer Landscape for a Healthy Diet
For those watching their nutritional intake, a few key considerations arise. Diet root beers offer a zero-calorie, sugar-free alternative, but these rely on artificial sweeteners. While generally recognized as safe, some individuals experience digestive issues like bloating or diarrhea from artificial sweeteners, particularly sugar alcohols. Therefore, diet options, while reducing sugar intake, aren't without their own potential downsides for some sensitive individuals.
Moreover, the medicinal properties often touted in historical root beers are largely absent from modern commercial versions. Any genuine health benefits associated with the original roots and herbs are now separated from the sugary, and sometimes caffeinated, beverage. For those interested in a natural, healthier version, making homemade root beer from a safrole-free extract is an option, allowing full control over the ingredients and sugar content.

Conclusion
In summary, the original root beer did not contain caffeine. The stimulant was never part of the traditional recipes developed from indigenous herbal infusions and colonial small beers. Its inclusion in a few modern brands, most notably Barq's, is an industry innovation rather than a historical trait. For a nutrition diet, the more significant concern is the high sugar content of regular root beer and the potential digestive effects of artificial sweeteners in diet versions. Understanding this history and the shift in ingredients is key to making informed dietary choices about this classic American beverage. It's a prime example of how a food's nutritional profile can evolve drastically over time, highlighting why checking modern labels is always essential.
