How to Make Root Beer
You can make homemade root beer to take full control of all raw materials. Here is a basic guide for how to make root beer. The process is simple and brings great practical value.
You first need to brew concentrated herbal base liquid. You boil sassafras bark, wintergreen leaf, cinnamon, cloves, star anise and vanilla bean in clean water for 30 minutes. You add two cups of sugar and appropriate molasses per gallon of liquid and stir the mixture until all solids dissolve. You mix in cold water to cool the liquid to room temperature. You add a quarter teaspoon of champagne yeast for each gallon of the mixture. The yeast generates carbonation within 24 to 48 hours. You refrigerate the finished drink immediately to terminate fermentation.
Time control acts as the core key to making qualified root beer. Refrigeration within 24 to 48 hours keeps the alcohol content below 0.5% ABV. Extended fermentation will turn the drink into an alcoholic beverage.
