What Is Root Beer Made Of

Root beer is a classic carbonated drink that has been loved by many for generations. With its sweet, earthy taste and distinct flavor profile, root beer stands out from other sodas and soft drinks. But what exactly gives root beer its signature flavor?

A Brief History of Root Beer

The origins of root beer can be traced back to the colonial days of America. Indigenous cultures like the Native Americans were known to use the extracts of the sassafras root and other botanicals to produce drinks and home remedies. Later, American colonists started experimenting with fermenting combinations of roots, barks, and herbs to create “small beers.”

Over time, these herbal beers evolved into the root beer we know today. The recipes varied across different regions based on the locally available ingredients. The term “root” in root beer comes from the key ingredients used – roots, barks, and herbs.

While originally alcoholic, root beer evolved into a non-alcoholic, soda-like beverage in America by the late 19th century. With mass commercialization, root beer became widely popular across the United States. Today, it comes in different styles – from traditional sodas to local craft root beers.

Key Ingredients Used in Root Beer

Key Ingredients Used in Root Beer

So what is root beer made of? There are a few key ingredients that give root beer its characteristic flavor profile.


The sassafras root is the original and most well-known root used in root beer. The oil extracted from sassafras contains a compound called safrole that gives root beer its distinctive aroma and flavor. Safrole has a sweet, spicy aroma with notes of anise and licorice.

However, commercial use of sassafras has been banned by the FDA since the 1960s due to the carcinogenic effects of safrole. Most mainstream root beers today use artificial sassafras flavoring or natural extracts with the safrole removed. Some smaller brewers still use authentic sassafras in limited quantities.


Wintergreen is another crucial ingredient used in root beer. The methyl salicylate compound in wintergreen leaves provides a minty, medicinal taste. Today, wintergreen is the predominant flavor used in many commercial root beers.


Warm spices like anise, cinnamon, nutmeg, and clove are commonly used to provide depth to root beer’s flavor profile. Star anise is paired with licorice root to replicate sassafras’ sweet licorice notes. Vanilla is also added for extra sweetness.

Other Flavorings

Other botanical ingredients like birch bark, ginger root, juniper berries, spruce tips, and honey can provide complexity to the flavor of root beer. Commercial versions may also contain caramel coloring and artificial flavors.

The Root Beer Making Process

So how exactly is this combination of roots, spices, and plant extracts turned into the beverage we know as root beer? Here is a quick look at the standard root beer production process:

  • Brewing: The roots, herbs, spices, and other ingredients are steeped in hot water to extract the flavors. This produces a concentrated liquid extract.
  • Sweetening: Sugar or other natural sweeteners like honey or molasses are added to sweeten the brewed extract.
  • Carbonation: The sweetened extract is combined with carbonated water and bottled. This gives root beer its signature bubbly, effervescent texture.
  • Flavoring: Other flavor extracts like vanilla or wintergreen can be added for extra complexity. Artificial flavors are used in some commercial root beers.
  • Bottling: The finished root beer is bottled in glass bottles or cans. Root beer obtains its carbonation from the pressurized bottles.

This traditional brewing method produces old-fashioned root beers with authentic flavor. However, most mainstream root beer brands use more modern and efficient bulk manufacturing methods.

The Distinct Flavor Profile of Root Beer

So what does a chilled mug of fresh root beer taste like? Here’s a look at some of the standout characteristics of root beer’s flavor:

  • Sweetness – Root beer has a pleasant sweetness, often described as maple-like. This sweetness comes from added sugar/honey or the natural sweetness of ingredients like licorice, vanilla, and anise.
  • Wintergreen – The predominant wintergreen flavor provides a cooling, minty taste and aroma. This adds to the drink’s refreshing appeal.
  • Spiciness – There are warming spice notes like cinnamon, clove, and sassafras that create depth.
  • Carbonation – The bubbly effervescence and fizz of root beer is part of its signature mouthfeel.
  • Mild acidity – Subtle, tangy acidity from ingredients like birch bark cuts through the sweetness.

The combination creates a complex, nuanced flavor – sweet but not too sugary, spiced but not hot, refreshing yet earthy. The taste is difficult to compare to any other soda!
