The same famous soft drinks made by the Sprecher Brewing Company in Milwaukee, Wisconsin. The syrups contain sodium benzoate, a preservative, which means that you cannot naturally carbonate this by adding yeast. They are perfect if you enjoy mixing and carbonating your own soda at home, or for use as toppings on Sundaes, or for any number of other uses! Your imagination is the limit. All flavors contain one gallon of concentrate and yield five gallons of soda.
