1. A method of controlling undesirable microorganism concentration in an aqueous solution employed in a fermentation process, the method comprising the steps of:
(a) introducing a fermentable carbohydrate to an aqueous solution; (b) introducing at least one yeast to said solution; (c) introducing a hops acid extract into said solution; and (d) introducing an organic acid into said solution;wherein the organic acid is selected from the group consisting of citric acid, benzoic acid, propionic acid and their salts.
