Root beer

Root beer is a North American beverage traditionally made using the root bark of the sassafras tree Sassafras albidum or the sarsaparilla vine Smilax ornata (also used to make a soft drink called sarsaparilla) as the primary flavor. It started out as a type of small beer that was brewed. Now root beer is typically a soft drink manufactured to be typically, but not exclusively, non-alcoholic, caffeine-free, sweet, and carbonated. It usually has a thick and foamy head.

Since safrole, a key component of sassafras, was banned by the U.S. Food and Drug Administration in 1960 due to its carcinogenicity, most commercial root beers have been flavored using artificial sassafras flavoring, but a few (e.g. Hansen's) use a safrole-free sassafras extract. There are many major root beer producers. A common use is to add vanilla ice cream to make a root beer float.

Root beer has been drunk in the United States since at least the eighteenth century. It has been sold in confectionery stores since at least the 1840s, and written recipes for root beer have been documented since the 1830s. In the nineteenth century, it was often consumed hot and was often used with medicinal intent. It was combined with soda as early as the 1850s; at that time it was sold as a syrup rather than a ready-made beverage.

Beyond its aromatic qualities, the medicinal benefits of sassafras were well known to both Native Americans and Europeans, and druggists began marketing root beer for its medicinal qualities.

Pharmacist Charles Elmer Hires was the first to successfully market a commercial brand of root beer. Hires developed his root tea made from sassafras in 1875, debuted a commercial version of root beer at the Philadelphia Centennial Exposition in 1876, and began selling his extract. Hires was a teetotaler who wanted to call the beverage "root tea". However, his desire to market the product to Pennsylvania coal miners caused him to call his product "root beer", instead.

In 1886, Hires began to bottle a beverage made from his famous extract. By 1893, root beer was distributed widely across the United States. Non-alcoholic versions of root beer became commercially successful, especially during Prohibition.

Not all traditional or commercial root beers were sassafras-based. One of Hires's early competitors was Barq's, which began selling its sarsaparilla-based root beer in 1898 and was labeled simply as "Barq's".

In 1919, Roy Allen opened his root-beer stand in Lodi, California, which led to the development of A&W Root Beer. One of Allen's innovations was that he served his homemade root beer in cold, frosty mugs. IBC Root Beer is another brand of commercially produced root beer that emerged during this period and is still well-known today.
