Root beer
A North American beverage with a foamy head and a history dating back to the 18th century.
Last updated
Root beer is a North American drink that originally got its main flavor from the root bark of the sassafras tree or the sarsaparilla vine. It began as a brewed small beer.
These days, it is typically a sweet, carbonated soft drink without alcohol or caffeine, and it often has a thick, foamy head. Because safrole—a key part of sassafras—was banned by the U.S. Food and Drug Administration in 1960 for causing cancer, most commercial root beers now use artificial sassafras flavoring, though a few brands have used a safrole-free sassafras extract. Many major producers exist, and a common way to enjoy it is by adding vanilla ice cream to make a root beer float.
History
People in the United States have been drinking root beer since at least the 1700s. It was sold in candy stores from the 1840s onward, and written recipes date back to the 1830s.
In the 1800s, it was often served hot and used for medicinal purposes. It was combined with soda water as early as the 1850s, sold as a syrup rather than a ready-to-drink beverage. Both Native Americans and Europeans knew about the medicinal benefits of sassafras, and druggists marketed root beer for its health qualities.
Pharmacist Charles Elmer Hires was the first to successfully market a commercial brand. He developed a root tea from sassafras in 1875, introduced a commercial version at the Philadelphia Centennial Exposition in 1876, and began selling his extract.
Hires, a teetotaler, originally wanted to call it "root tea," but he changed the name to "root beer" to appeal to Pennsylvania coal miners. In 1886, he started bottling a beverage from his extract, and by 1893, root beer was widely distributed across the United States. Non-alcoholic versions became commercially successful, especially during Prohibition.
Not all root beers were sassafras-based. Barq's, an early competitor, began selling a sarsaparilla-based root beer in 1898, simply labeled "Barq's." In 1919, Roy Allen opened a root beer stand in Lodi, California, leading to A&W Root Beer. Allen’s innovation was serving his homemade root beer in cold, frosty mugs. IBC Root Beer also emerged during this period and remains well-known.
The FDA banned safrole in commercially mass-produced foods and drugs in 1960 after lab animals given large doses of sassafras tea or oil developed liver damage or cancer. While sassafras is no longer used in commercial root beer, natural extracts with safrole removed are available. A Museum of Root Beer opened in Wisconsin Dells in 2021.
Traditional method
A traditional recipe involves cooking a syrup from molasses and water, cooling it for three hours, then mixing in root ingredients like sassafras root, sassafras bark, and wintergreen. Yeast is added, and the beverage ferments for 12 hours, then is strained and rebottled for secondary fermentation. This usually results in 2% alcohol or less, though it can be modified to make a stronger "hard root beer."
Foam
Root beer originally got its thick, lasting foam from the mucilaginous properties of sassafras root and bark. It was first carbonated by fermentation, but as demand grew, carbonated water replaced that process. Some manufacturers now use small amounts of starch (like from cassava) with natural surfactants to recreate the foamy character. Certain brands have distinctive foaming behaviors that became part of their marketing.
Ingredients
Commercial root beer is now produced in Canada and every U.S. state. While most popular in North America, some brands are made in or imported by countries such as Australia, the United Kingdom, Malaysia, Argentina, Germany, the Philippines, Singapore, Taiwan, South Korea, Indonesia, Sweden, Vietnam, and Thailand.
No standard recipe exists, but modern root beer typically includes filtered water, sugar, and safrole-free sassafras extract, along with other flavors like vanilla, caramel, wintergreen, black cherry bark, licorice root, sarsaparilla root, nutmeg, acacia, anise, molasses, cinnamon, sweet birch, and honey. Soybean protein or yucca may be added for foam, and caramel coloring gives the drink its brown hue. Early and traditional recipes also included ingredients like allspice, birch bark, coriander, juniper, ginger, wintergreen, hops, burdock root, dandelion root, spikenard, pipsissewa, guaiacum chips, sarsaparilla, spicewood, wild cherry bark, yellow dock, prickly ash bark, sassafras root, vanilla beans, dog grass, molasses, and licorice—many of which are still used today in traditional or commercial versions, often thickened, foamed, or carbonated.
Lore & Background
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. Safrole, the aromatic oil found in sassafras roots and bark that gave traditional root beer its distinctive flavor, was banned in commercially mass-produced foods and drugs by the FDA in 1960. Laboratory animals that were given oral doses of sassafras tea or sassafras oil that contained large doses of safrole developed permanent liver damage or various types of cancer.
Reader's Guide
One traditional recipe for making root beer involves cooking a syrup from molasses and water, letting the syrup cool for three hours, and combining it with the root ingredients (including sassafras root, sassafras bark, and wintergreen). Yeast was added, and the beverage was left to ferment for 12 hours, after which it was strained and rebottled for secondary fermentation. This recipe usually resulted in a beverage of 2% alcohol or less, although the recipe could be modified to produce a more alcoholic beverage (such variation is called 'hard root beer').
Root beer was originally made with sassafras root and bark which, due to its mucilaginous properties, formed a natural, long lasting foam, a characteristic feature of the beverage. Root beer was originally carbonated by fermentation. As demand and technology changed, carbonated water was used.
Some manufacturers used small amounts of starch (e.g. from cassava) with natural surfactants to reproduce the familiar foaming character of sassafras-based root beer. Some brands of root beer have distinctive foaming behaviors, which has been used as part of their marketing identity. Although this beverage's popularity is greatest in North America, some brands are produced in or imported by other countries, including Australia, the United Kingdom, Malaysia, Argentina, Germany, the Philippines, Singapore, Taiwan, South Korea, Indonesia, Sweden, Vietnam, and Thailand. While no standard recipe exists, the primary ingredients in modern root beer are filtered water, sugar, and safrole-free sassafras extract, which complements other flavors.
Common flavorings are vanilla, caramel, wintergreen, black cherry bark, licorice root, sarsaparilla root, nutmeg, acacia, anise, molasses, cinnamon, sweet birch, and honey. Soybean protein or yucca are sometimes used to create a foamy quality, and caramel coloring is used to make the beverage brown. Ingredients in early and traditional root beers include allspice, birch bark, coriander, juniper, ginger, wintergreen, hops, burdock root, dandelion root, spikenard, pipsissewa, guaiacum chips, sarsaparilla, spicewood, wild cherry bark, yellow dock, prickly ash bark, sassafras root, vanilla beans, dog grass, molasses and licorice.
