The Core Ingredients of Classic A&W Root Beer
At its foundation, classic A&W Root Beer is a blend of seven primary ingredients, which may vary slightly by region due to local regulations. For the U.S. market, these are:
- Carbonated Water: The base of any soda, providing the fizz and effervescence.
- High Fructose Corn Syrup: The main sweetener, giving the beverage its sugary flavor profile.
- Caramel Color: Used to give the root beer its signature dark brown hue.
- Sodium Benzoate: A common food preservative used to prevent the growth of bacteria and yeast.
- Natural and Artificial Flavors: A proprietary blend of essences that create the unique taste.
- Quillaia Extract: Derived from the soapbark tree, this extract is used as a foaming agent to create the classic thick, frothy head.
- Citric Acid: A natural acidulent that can enhance flavor and act as a preservative.
Deconstructing the Flavor Profile: Natural and Artificial
While the label lists "natural and artificial flavors," the actual flavor profile of A&W is much more complex than a single line item suggests. Since the U.S. Food and Drug Administration banned safrole, the oil in sassafras root, in 1960 due to its potential carcinogenicity, modern root beer recipes had to evolve. Today's flavor is a careful and often secret combination of synthetic and natural compounds that mimic the traditional blend of spices and botanical notes.
The Secret Behind the Creamy, Foamy Head
The rich, creamy foam is one of A&W's most recognizable characteristics, especially when served in a frosty mug. This is achieved through the use of Quillaia extract, which acts as a natural emulsifier and foaming agent. It is important to note that this is different from the ingredients used in traditional fermented root beers, which achieved their foam through natural fermentation processes.
Nutritional Considerations
A&W Root Beer is a calorie-dense beverage due to its high sugar content, primarily from high fructose corn syrup. For instance, a 12-ounce can contains approximately 170 calories and 45 grams of sugar. The beverage is also notable for being entirely caffeine-free, a feature that has been part of its marketing for many years.

The Evolution of Root Beer Ingredients
The transition away from sassafras-based recipes is a crucial point in root beer history. Historically, indigenous North American tribes used sassafras root for medicinal purposes before it was adopted for beverages. The commercialization of root beer began in the 19th century, with early versions being slightly alcoholic and fermented. The modern, mass-produced soft drink evolved after the FDA's ban on safrole in the 1960s. Today, companies rely on carefully formulated extracts and flavors to recreate the classic taste safely and consistently.

Conclusion: What Does A&W Root Beer Contain?
In summary, the classic A&W Root Beer is a combination of carbonated water, high fructose corn syrup, and a complex blend of natural and artificial flavors that mimic traditional spices like vanilla and wintergreen. Its signature foamy head is created by the addition of Quillaia extract, and it remains a popular choice for many, partly due to its caffeine-free nature. While the core ingredients are standardized for safety and mass production, the brand continues to deliver a consistent, nostalgic flavor that has captivated root beer lovers for over a century. A&W offers a taste of classic American soft drink tradition, carefully crafted to be safe and consistently delicious in every can and frosty mug.
