Easy Root BeerThis recipe uses root beer extract, so it’s the one to try if you want the traditional flavor of root beer. You’ll need a 1-gallon plastic bottle for mixing the soda.
1 gallon water
2 cups sugar
2 tablespoons root beer extract
1/4 to 1/2 teaspoon champagne yeast
In a large stockpot, heat the water until warm, about 100 to 110 degrees. Using a funnel, pour the sugar and the extract into a gallon bottle. Next, pour half of the warm water into the same bottle. Then add the yeast to the bottle, attach the bottle cap and shake well. Add the remaining water, then shake again. Pour into 2-liter bottles and attach the bottle caps. Leave 1 to 2 inches of empty space at the top of each bottle. Write the date on the bottles and store them in a warm, draft-free place, ideally at room temperature (68 to 77 degrees) for 2 to 3 days. Then refrigerate the bottles. Makes 1 gallon.
