Ingredients

  • 3 lbs white sugar – for sweetness and fermentation fuel
  • 2 oz sassafras root bark (organic, dried)
  • 1 oz sarsaparilla root (dried)
  • 1 oz licorice root (dried)
  • 1 tbsp wintergreen leaves (dried)
  • 1 tbsp vanilla extract (natural)
  • 1 tbsp molasses – adds depth and color
  • 1 tsp yeast (champagne yeast or ale yeast recommended)
  • 5 gallons filtered water
  • Optional: 1 tbsp ginger root (fresh or dried, for a spicy kick)

Equipment

  • 5-gallon food-grade fermentation bucket with lid
  • Large stockpot (at least 6 gallons) for boiling
  • Fine mesh strainer or cheesecloth
  • Measuring cups and spoons
  • Sanitized bottles with caps (glass or PET plastic soda bottles recommended)
  • Funnel for bottling
  • Hydrometer (optional, for measuring sugar levels)
  • Thermometer to monitor liquid temperature
  • Stirring spoon (preferably stainless steel or food-grade plastic)

Instructions

  1. Prepare the root bark and herbs: In your large stockpot, combine the sassafras root bark, sarsaparilla root, licorice root, wintergreen leaves, and optional ginger root. Add about 2 gallons of filtered water.
  2. Boil and simmer: Bring the mixture to a boil, then reduce heat and simmer gently for 1 hour. This will extract the flavors from the roots and herbs.
  3. Strain the mixture: After simmering, carefully strain the liquid through a fine mesh strainer or cheesecloth into your fermentation bucket. Discard the spent roots and herbs.
  4. Add sugar and molasses: While the liquid is still warm (around 70-80°F), stir in the white sugar and molasses until fully dissolved. This will feed the yeast and add richness to your root beer.
  5. Cool the mixture: Add the remaining filtered water to bring the volume up to 5 gallons. Allow the liquid to cool to about 70°F to avoid killing the yeast.
  6. Add vanilla and yeast: Stir in the vanilla extract. Then sprinkle the yeast evenly over the surface of the liquid. Allow it to hydrate for 10 minutes, then stir gently to mix.
  7. Seal and ferment: Secure the lid on your fermentation bucket. Place it in a dark, room-temperature spot (68-72°F) for 2 to 3 days. You’ll notice bubbling as fermentation begins—this is good!
  8. Check fermentation progress: After 2 days, taste a small sample. If it’s fizzy and slightly sweet, it’s ready for bottling. If not, wait another day but don’t exceed 4 days to avoid overcarbonation.
  9. Bottle your root beer: Using your funnel, carefully transfer the root beer into sanitized bottles, leaving about 1 inch of headspace. Seal tightly.
  10. Carbonate and chill: Store bottles at room temperature for 2-3 days to build carbonation. Then refrigerate to stop fermentation and chill before serving.

Tips & Variations

“For a clearer root beer, you can cold crash the fermentation bucket by placing it in a cool area (around 40°F) for 24 hours before bottling.”

If you want a less sweet root beer, reduce the sugar by 10-20%. Alternatively, for a spicier version, increase the ginger root or add a cinnamon stick during the simmering phase.

If you prefer a caffeine boost, consider steeping some tea leaves with the roots.

Experiment with natural sweeteners like honey or maple syrup instead of white sugar, but be aware these may affect fermentation rates. Also, always sanitize your equipment to prevent unwanted bacteria and off-flavors in your brew.
