Barley is mainly used to obtain the required malt for the brewing process. The addition of food color, flavorings, or sweeteners is not permitted. Korn differs from vodka in that it is distilled to lower alcoholic proofs and less rigorously filtered, which leaves more of the cereal grain flavor in the finished spirit.
