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. 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.

Method and system for producing ultra-high gravity alcoholic beverages

A system and method are provided to produce a beverage concentrate such as a beer extract. A forward osmosis (FO) filtration technique removes pure water from a conventional brewed beer; accordingly, the beer extract can be produced without distillation or other alteration steps that may negatively impact of flavor and aroma components of the beer. A draw solution is used to provide a differential osmotic pressure through a FO filtration device. The diluted draw solution is recycled by reverse osmosis, distillation, and combinations thereof.
