Ten gallons water, four quarts molasses, two quarts sound corn, crushed or ground. Put all into a keg and shake well; in a few days a fermentation will have been brought on as nicely as with yeast. Keep it bunged tight. It may be flavored with oil of lemon, etc. The corn will last five or six makings. If it gets too sour add more molasses and water in the above proportions. This drink is cheap, healthy, and there is no better with yeast.
