Abstract: Methods and systems are described that produce an ultra-high gravity alcoholic beverage from a high gravity alcoholic beverage stream using an efficient, low waste, combination reverse osmosis and forward osmosis system and an enhanced draw solution. Utilizing a reverse osmosis system prior to using a forward osmosis system in removing water content from a high gravity alcoholic beverage stream significantly reduces a draw solution load when compared to a process that utilizes a forward osmosis system alone or prior to using any other dewatering system. In addition, the enhanced draw solution, comprising at least one of acetaldehyde, amyl acetate, ethyl acetate, ethyl hexanoate, ethyl octanoate, iso-amyl acetate, iso-amyl alcohol, iso-butanol, n-propanol, pentyl acetate, and phenyl ethyl alcohol, offers an efficient and low-cost alternative to ethanol-based draw solutions.

Abstract: Methods and systems are described that filter and stabilize ultra-high gravity alcoholic beverages produced by forward osmosis. A rough ultra-high gravity alcoholic beverage may be received from a dewatering system and then passed on to a chiller as part of a post dewatering process. The ultra-high gravity alcoholic beverage may be held at a predetermined temperature for a specific amount of time such that the temperature of the ultra-high gravity alcoholic beverage is prevented from falling below a freezing point of the ultra-high gravity alcoholic beverage. The chilled ultra-high gravity alcoholic beverage is then passed through a number of filters of a filtration system. The filters may be arranged in an order progressing from coarse to fine filters, where haze compounds and their precursors are removed from the ultra-high gravity alcoholic beverage producing a clear and stable product.
