A method comprising manipulating the concentration of at least one preselected member of a plurality of volatile components including an alcohol and water present in an alcoholic beverage in which substantially any predetermined desired concentrations of alcohol and water in an alcoholic beverage are provided, while preserving the flavor and aroma of the alcoholic beverage by; (a) providing a membrane having a feed side and a permeate side opposite feed side, said membrane being permeable to said at least one preselected member; (b) contracting said alcoholic beverage against said feed side of said membrane; (c) contacting a gas-phase extraction fluid against said permeate side membrane, said extraction fluid comprising a vapor mixture capable of arbitrating the pervaporation of said volatile components such that a portion of said preselected member passes from said feed side of said membrane to said permeate side of said membrane and mixes with said extraction fluid, while a substantial portion of the remaining members of said plurality of volatile components is retained in said alcoholic beverage on said feed side of said membrane; and (d) allowing said alcoholic beverage and said extraction fluid to remain in contact with said feed side and said permeate side of said membrane, respectively, for a period of time sufficient to provide a second liquid on said feed side of said membrane in which the concentration of said preselected member has been manipulated to the desired level.
