William G Light: Production of low alcoholic content beverages. Allied Corporation, Thomas K McBride, John F Spears Jr, Raymond H Nelson, October 14, 1986: US04617127 (29 worldwide citation)

Low alcohol content beverages may be obtained by passing a high alcohol content beverage through a reverse osmosis system to form a permeate and a retentate. The permeate comprising mainly alcohol and water is removed. A minor portion of the retentate is recovered as product while a major portion of ...

William G Light: Production of low alcoholic content beverages. Allied Corporation, Thomas K McBride, John F Spears Jr, Raymond H Nelson, January 5, 1988: US04717482 (9 worldwide citation)

Alcoholic beverages may be passed through a reverse osmosis system to form a permeate and a retentate. The permeate will comprise mainly alcohol and water and will be removed as will a minor portion of the retentate which is recovered as product. The major portion of the retentate is recycled back t ...
