The great thing about brewing root beer at home is that anyone can do it. In fact it's an amazingly uncomplicated process.
Root beer is simply water that has been sweetened, flavored and carbonated.
You can combine these ingredients at home to produce nearly the same drink. Root beer, like other soft drinks, is created and packaged in a basic six-step process. Second, a syrup base is created from using flavorings, sweeteners, colorings, etc., and added to the water. Third, carbon dioxide is added. Fourth, the liquid is transferred to individual bottles or cans and immediately sealed.
