Root Beer Kombucha

  • Total Time:
    2 days

  • Yield:
    16 Servings 1x


Root beer kombucha is a healthy take on a classic soda flavor. This recipe uses real sasparilla root and wintergreen leaves that provide lots of flavor and health benefits.




  1. Combine the water, sarsaparilla root, and wintergreen leaves in a medium saucepan. Bring to a boil.
  2. Reduce the heat and simmer for 20 minutes.
  3. Strain the herbs from the liquid.
  4. Add the cane sugar, molasses, vanilla extract, and lime juice while the liquid is still warm. Stir until the sugars dissolve.
  5. Cool the mixture to room temperature.
  6. Pour 1/3 cup of the root beer mixture into each glass bottle.
  7. Fill the bottle with kombucha, leaving 1-inch headspace. Cap the bottles tightly.
  8. Let the bottles ferment at room temperature for 2-3 days.
  9. Refrigerate to stop the fermentation. Enjoy when desired.


Store extra root beer mixture in the fridge for up to 2 weeks.

Black kombucha tea works best because the bold flavor compliments the intense flavors of the herbs. White or green tea kombucha would be overpowered by the other flavors.

If you can’t find wintergreen, you can substitute mint. It’s not quite as sweet or powerful, so you may want to use a few extra leaves and increase the sugar to 3/4 cup.

You could substitute maple syrup for molasses if you prefer. Maple syrup is sweeter and less tangy than molasses, so your root beer kombucha may be a bit sweeter and more mellow.

Add a scoop of vanilla ice cream to each serving for a fun and sweet treat.

  • Cook Time: 15 minutes

What Does Root Beer Kombucha Taste Like?

Root beer kombucha tastes a bit like root beer soda. It’s not quite as sweet as store-bought root beer, but it still has plenty of flavor and fizz. The tangy kombucha and sarsaparilla root balance against the sweetness of the cane sugar and molasses. You’ll also notice hints of vanilla and tones of licorice.

What Is Sarsaparilla Root?

Sarsaparilla root, Smilax ornata, is a climbing vine native to Central America and Mexico. The vines are large, prickly, and perennial, and the roots are short and thick. It has a slightly bitter taste that can overwhelm your beverage. It is often paired with sweet ingredients to help balance its bold flavor. Sarsaparilla soda led to the creation of root beer.

People have used sarsaparilla for centuries to treat skin irritations and joint problems like arthritis. Today you can find sarsaparilla root in certain health food stores and online at Amazon. It comes in tablets, capsules, powder, and tinctures.

Sarsparilla may be harmful to pregnant women and people with kidney disease. It’s advised that these individuals avoid sarsaparilla root. Always check with your doctor before adding a medicinal herb to your routine.

Don’t confuse sarsaparilla root with sassafras. Sassafras was used to make root beer for many years until the FDA discovered it contained a carcinogen. Sassafras is not safe to use.

Wintergreen is a perennial evergreen native to eastern North America. This shrub is small, with waxy leaves and red berries. Wintergreen leaves can help relieve headaches and gas and may help reduce fevers.

How Much Caffeine Does Root Beer Kombucha Have?

Root beer kombucha has 10-15 mg of caffeine per 8 oz serving. Black tea, a main ingredient in kombucha, has caffeine. During fermentation, the caffeine provides the SCOBY with nitrogen. Nitrogen helps create the beneficial yeast and bacteria that make kombucha a healthy probiotic drink.

Should You Make This Recipe with Young, Sweet Kombucha or Older, Sour Kombucha?

Make this recipe with young, sweet kombucha. The bitter sarsaparilla root and sharp wintergreen flavors will pair nicely with sweet kombucha.

Old, sour kombucha pairs well with sweet fruits or as a starter tea for your next batch of kombucha.

Sarah first tried kombucha in 2015 and she was hooked. Her favorite flavor is ginger, but cranberry comes in a close second. She made her own for many years and loved experimenting with fruit flavors.
