ABSTRACT:
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 to the reverse osmosis system to admix with fresh beverage and added water. The product will comprise a beverage containing a lower alcoholic content than was possessed by the fresh beverage. The semipermeable membrane which is utilized in the reverse osmosis process will possess a chloride ion rejection rate greater than about 80% at 400 pounds per square inch net pressure.
