Method and system for the filtration and stabilization of ultra-high gravity alcoholic beverages

A method for filtering and stabilizing ultra-high gravity (UHG) alcoholic beverages produced by a forward osmosis (FO) system, the method comprising:

• processing, via reverse osmosis (RO), a high gravity (HG) alcoholic beverage to produce a very-high gravity (VHG) alcoholic beverage, wherein the VHG alcoholic beverage comprises a greater alcohol by volume percentage than the HG alcoholic beverage;
• processing, via FO, the VHG alcoholic beverage processed via RO, to produce the UHG alcoholic beverage, wherein the UHG alcoholic beverage comprises a greater ABV percentage than the very-high gravity alcoholic beverage;
• conveying the UHG alcoholic beverage into a chilled holding tank set at a temperature within a range of −3° C. to −8° C., wherein the UHG alcoholic beverage having 24% to 50% ABV;
• maintaining the UHG alcoholic beverage in the chilled holding tank for a holding time set between 20 minutes and 24 hours such that the temperature of the UHG alcoholic beverage is within the range of −3° C. to −8° C., and wherein the temperature of the UHG alcoholic beverage is prevented from falling below a freezing point of the beverage;
• pumping, after expiration of the holding time, the UHG alcoholic beverage from the chilled holding tank through a multi-stage filtration system comprising filters arranged in an order progressing from coarse particle size filtration elements to fine particle size filtration elements, wherein the UHG alcoholic beverage contains haze compounds prior to entering the filtration system, and wherein filtration system removes the haze compounds from the UHG alcoholic beverage;
• and
• collecting, via a storage tank, the UHG alcoholic beverage pumped through the multi-stage filtration system.
