Very fun recipe. Makes 5 gallons and is excellent for a large family gathering. I like to make on the 4th of July along with homemade vanilla icecream and everyone enjoys floats. Healthier than store bought! I've also posted the recipe for brewing your own root beer using the yeast method if you would like to try that instead!

Ingredients Nutrition

  • 5 gallons water
  • 5 lbs dry ice
  • 5 lbs sugar
  • 2 ounces root beer extract

Directions

  1. Stir together water and sugar in a 5-gallon beverage container.
  2. Stir in root beer extract.
  3. Add 1.5 pounds dry ice and add more as needed. Don't add all at once, because it will freeze the bottom few inches of root beer (found this out by mistake :) !)
  4. After about 15 minutes, the root beer will be carbonated and ready to go.
