Root beer flavor is primarily made from the roots of the sassafras tree, which give it its distinctive and aromatic taste. The sassafras tree, native to North America, has a long history of being used for both medicinal and culinary purposes. Its roots contain essential oils and compounds that contribute to the unique flavor profile of root beer.
The use of sassafras root in root beer can be traced back to Native American tribes, who used it for its medicinal properties. They believed that the roots had various health benefits, such as treating fever, rheumatism, and gastrointestinal issues. The aromatic nature of the sassafras root also made it a popular ingredient in traditional remedies and tonics.
As settlers arrived in America, they adopted the use of sassafras root in their own beverages. In the 19th century, root beer started gaining popularity as a non-alcoholic alternative to beer. It was often brewed at home using a combination of herbs, roots, and other botanicals. Sassafras root became a key ingredient, lending its distinct flavor and fragrance to the beverage.
To create the root beer flavor, the sassafras root is typically harvested, dried, and ground into a fine powder. This powder is then used in the brewing process to infuse the beverage with its characteristic taste. Other ingredients, such as wintergreen, anise, and licorice, are often added to enhance the complexity of the flavor profile.
It is important to note that the use of sassafras root in commercial root beer has decreased over time due to concerns about its safety. The FDA banned the use of sassafras oil in food and beverages in the 1960s due to the presence of a compound called safrole, which has been shown to be carcinogenic in animal studies. However, the ban does not extend to the use of sassafras leaves or bark, which are still used as flavorings in some root beer products.
In response to the ban, many root beer manufacturers turned to artificial flavorings and extracts to mimic the taste of sassafras root. These artificial flavorings attempt to capture the essence of sassafras without the potential health risks associated with safrole.
The flavor of root beer is a complex blend of botanicals, with the sassafras root playing a prominent role. Its fragrant and aromatic qualities, combined with other herbs and spices, create the distinct and nostalgic taste that has made root beer a beloved beverage for generations.
In my experience as a sommelier and brewer, I have had the opportunity to taste a variety of root beers, both traditional and modern. While the use of sassafras root may vary among different brands, its presence is often noticeable in the overall flavor profile. The aroma of sassafras, with its hints of spice and earthiness, adds depth and character to the beverage. It is fascinating to see how the use of sassafras root in root beer has evolved over time, reflecting both the traditions of the past and the advancements in flavoring technology.
