Make homemade root beer by using 2 ounces of McCormick Root Beer Concentrate, 5 pounds of sugar, 5 gallons of water, a pack of dry yeast and 1 cup of boiled water. You also need a 5-gallon bucket suitable for wine or home brewing in addition to bottling equipment.
The recipe for making homemade root beer takes 30 minutes to prepare, but it requires several days to properly brew. Keep the completed mixture in a 5-gallon brewing bucket or in tightly sealed single-serve brewing bottles. McCormick suggests maintaining a 70 to 80 degree Fahrenheit environment for two to three days before changing the temperature to between 40 and 45 degrees Fahrenheit for an additional four to five days.
In addition to using a root beer concentrate, you can also purchase kits that contain the bottles, sugars, concentrates and fermenting instructions. These kits make between four and six bottles and can be purchased through a variety of home brewing stores both online and offline.
Make sure to clean and sanitize all bottling equipment, including the tongs, caps and funnels, to ensure that no bacteria reaches the root beer during the bottling or fermenting stages. Check on the bottles during the fermentation process to ensure that there is no chance of explosion.
