Abstract: The present invention provides methods and for the dealcoholization of alcohol containing solutions, especially fermented beverages. In preferred embodiments the methods employ a novel controlled-strip evaporative perstraction technique following initial clarification to remove biomass, wherein strip solutions, dealcoholized beverage, or both are recycled for use in the strip solutions for dealcoholization of subsequent batches of feed beverage. In further preferred embodiments additives are introduced into the strip solution to further limit loss of volatile components during perstraction. Biomass removed by the clarification is then returned to the retentate product following perstration.
