A method for preparing beer or cider concentrate including alcohol and volatile components of beer or cider flavor, and beer or cider prepared therefrom. The method includes a two step concentration method in which the first step involves a high efficiency nanofiltration that results in a highly concentrated retentate and an aqueous permeate fraction comprising alcohol and volatile flavor components. The second step involves removing water from said permeate fraction to obtain a highly concentrated alcohol solution also having volatile flavor components. The highly concentrated alcohol solution is then combined with the retentate from the first step into a final high alcohol and flavor beer or cider concentrate.

A method of reducing haze by creating a physically stable alcoholic beverage that has been obtained via filtration and separation processes includes receiving retentate from which water has been removed, from a reverse osmosis filter system having an initial alcoholic precursor to the alcoholic beverage in a feed stream, wherein a concentration of alcohol in the retentate has reached between about 10% and 40% by volume, cooling the retentate to a temperature between about 2 degrees below a freezing point of the retentate and a freezing point of the initial alcoholic precursor to the alcoholic beverage in the feed stream, and subjecting the retentate to a clarification process that removes particles having a size of about 0.4-0.8 microns and larger to produce a clarified retentate. The clarification process includes centrifuging, filtration using a filter, and/or forming a supernate and a precipitate and then decanting the supernate.

The invention relates to a fluid treatment device comprising a stirring element and at least one magnetic device. The stirring element has a plurality of flutes within its central portion, and the magnetic devices are placed around the stirring element. The device can further comprise a UV irradiation module and an on-line analysis module.

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.

The invention relates to a fermented beverage as well as a method of producing a fermented beverage, particularly a beer or beer-like beverage, with an ethanol content of between 0.0% and 1.0% by volume, the method comprising providing an ethanol containing fermented base beverage, reducing the ethanol content of the fermented base beverage by a de-alcoholisation step, followed by adding flavor to the fermented base beverage with reduced ethanol content to produce the fermented beverage, wherein the added flavor includes at least an amount of 4-vinyl guaiacol (4VG).

A method for removing one or more congeners from an alcoholic composition, including placing a quantity of an alcoholic composition in a pressure-controllable environment, decreasing the pressure of the pressure-controllable environment, removing one or more unwanted congeners from the alcoholic composition to yield a purified alcoholic composition, and removing the purified alcoholic composition from the pressure-controllable environment.
