What is root beer?

Root beer is a distinctly American drink with a sweet, herbal flavor that's been made since the colonial era. Traditionally, brewers made the drink by fermenting an herbal decoction made with sassafras bark, sarsaparilla root and other herbs with sugar and yeast to make a naturally bubbly, probiotic soft drink.

In the 20th century, the traditional herbal recipe fell from favor, and soft drink manufacturers began making it with artificial flavors. Moreover, they stopped culturing root beer and, instead, carbonated it.

Herbs for Homemade Root Beer

While most home brewers make their root beers from artificially flavored root beer extracts, there’s a certain undeniable charm of brewing root beer the traditional way. Slowly simmering a decoction of roots, bark and spices, adding a touch of sugar, and then stirring in a starter.

Then all you have to do is bottle the brew and wait for those beneficial bacteria and yeast to do their work.

Sassafras, sarsaparilla, ginger root and birch all give the brew its distinctive flavor, but without the additives.

• Sassafras gives root beer its distinctive, slightly mint-like flavor. And it's traditionally used to purify the blood in folk medicine (1).
• Sarsaparilla is traditionally used as a renal tonic and for the complexion (2)
• Ginger gives this root beer recipe a rich, fiery note. Herbalists use ginger to support cardiovascular and metabolic health, as well as for nausea and stomach upset. (3)
• Licorice gives the recipe a subtle, anise-like sweetness that pairs well with sassafras. Licorice also supports adrenal health (4), and may be helpful in addressing hormonal imbalance in women (5).
• Dandelion Root adds the subtlest bitter note to the brew. Dandelion root also supports liver health (6).

How to Make Root Beer

There's three basic steps to making homemade root beer. First, you'll start by making an herbal decoction by simmering the herbs in water until they release their aromatic compounds and other constituents. Then you'll sweeten the brew and add a starter culture, so that it ferments. Lastly, you'll bottle the root beer and let it culture.

As it ferments, all the microbes in your starter culture will consume the sweetener. As a result, your root beer will be fizz and bubble. And it's a great source of probiotics, too.

Brewing Tips

Homemade root beer is easy to make, and is just about as simple as boiling water or making tea. But, there's a few things to keep in mind as you make this recipe.

• Start with cold water. Tossing herbs straight into hot water may cause proteins in the herbs to seize, preventing the full release of their aromatic compounds and phytonutrients. Cold water eases this process.
• Add the sassafras last. While most woody herbs need time to release their flavor, sassafras is deeply aromatic and its aroma dissipates quickly with prolonged cooking. So toss it into the pot toward the end of simmering for best flavor.
• Switch up the sweetener. This root beer recipe uses unrefined cane sugar, but you can you can also try maple syrup, maple sugar, coconut sugar and honey. Just make sure you use a caloric sweetener so that the root beer ferments.
• Add your starter only once the herbal mixture cools. If you add your starter to the hot herbal decoction, the heat will kill the wild bacteria and yeasts. So add the culture only when the decoction cools to room temperature.
• Use flip-top bottles. Flip-top bottles effectively capture all the carbon dioxide that builds up during fermentation - which means a fizzy brew for you.
• Pay attention to temperature in your kitchen. Homemade root beer will ferment faster in a warm kitchen, and more slowly in a cold one.
