Hello, I'm a beverage expert with a deep knowledge of the various ingredients and histories of different drinks. Now, let's address your question about root beer.

Root beer traditionally does not contain alcohol. It is a sweet, fizzy beverage that is often categorized as a soda or a soft drink. The original recipe for root beer was created using the Sassafrass tree's root as a base flavor, which is where it gets its name. Over time, the recipe has evolved, and modern root beer typically includes a variety of other ingredients such as vanilla, cinnamon, and wintergreen, among others. These ingredients are combined to create a unique flavor profile that is both sweet and slightly medicinal, but they do not include alcohol.

However, it's important to note that there are some craft or artisanal versions of root beer that may be brewed with a small amount of alcohol. These are not the standard commercial versions you would find in most stores but are specialty products that are often made by small, independent breweries. So, while most root beers are non-alcoholic, there are exceptions in the craft beverage market.
