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.

Described herein is a method for preparing a dehydrated and de-alcoholized flavor composition by decreasing or removing water and ethanol from a flavor composition, the method including the steps of treating the flavor composition by a dehydration process and dealcoholization process. Also described herein are flavor compositions obtainable by this method, flavored consumer products comprising the same, and methods and uses thereof.

A method for reducing beverage loss during loading of beverage into an ethanol concentration system having a set of reverse osmosis pressure vessels, each pressure vessel having a feed inlet, a retentate outlet, and a permeate outlet. The method includes feeding deaerated water into the feed inlet of a first pressure vessel, feeding the beverage into the feed inlet of the first pressure vessel, monitoring an alcohol percentage at the retentate outlet of a second pressure vessel, the second pressure vessel coupled directly or indirectly to the first pressure vessel, and coupling a retentate from the retentate outlet of the second pressure vessel to a feed tank coupled to the feed inlet of the first pressure vessel when the alcohol percentage is within a first target range of 0.5 to 18% alcohol-by-volume (ABV).

A method for preparing an aromatic beverage is as follows. The method includes subjecting a fermented beverage to a first filtration step including nanofiltration or ultrafiltration to obtain a retentate fraction and a permeate fraction including alcohol and volatile flavour components. Then, the method includes subjecting the permeate fraction including alcohol and volatile flavour components to a second filtration step of reverse osmosis to obtain a base liquid of at least 2% ABV. Combining the base liquid with exogenous aromas thereby obtains the aromatic beverage. Desirable fermented beverages are a beer or a cider.

The invention relates to an adsorption system (10) for accumulating flavoring substances, comprising at least one working chamber (12) in which at least one sorption agent is provided as a stationary phase and can be subjected to a flavoring substance-containing fluid which can be conducted through the working chamber as a mobile phase for attaching flavoring substances, wherein the flavoring substance-containing fluid is a food item from the group of beer-containing staple and/or luxury food items, beer wort, hops, hop extract, malt water, malt beer, malt wort and brewery-specific ingredients and products and/or is obtained by means of a dealcoholizing device from an ethanol-containing food item from the group of beer-containing staple and/or luxury food items, wherein a ratio of an average cross-sectional thickness to the total length of the at least one working chamber (12) is at most 0.3. The invention also relates to a method for operating such an adsorption system (10), a flavoring substance concentrate and a deflavored permeate which can be and/or are obtained by means of such an adsorption system (10) and/or by means of such a method from a flavoring substance-containing fluid, as well as to a beer which can be or is obtained by mixing an at least partially dealcoholized and/or fermentation-halted beer having such a flavoring substance concentrate.
