Treating a non-wine alcoholic beverage including: exposing the non-wine alcoholic beverage to an ion exchange matrix. The ion exchange matrix includes a mixture of cation exchange media and anion exchange media that includes: (1) cation exchange media that are in hydrogen form, (2) cation exchange media that are in mineral form comprising potassium mineral form, (3) anion exchange media that are in hydroxide form, and (4) anion exchange media that are in chloride mineral form. The exposing results in: binding ions of the mixture to one or more cationic or anionic constituents present in the pretreated beverage, reducing concentrations of the one or more cationic or anionic constituents in the beverage and maintaining a conductivity value of the treated beverage equal to or greater than the pretreated beverage's conductivity value. An apparatus for treating a non-wine alcoholic beverage and a treated non-wine alcoholic beverage prepared by a process are also disclosed.

Provided are crosslinked polyvinylpyrrolidone (PVPP) compositions and their use in beverage treatment. Provided is a dry, direct compressed tablet comprising at lease 70 wt % crosslinked PVPP. Also provided is the use of said tablet for the filtering and/or removing polyphenol of a liquid, preferable a beverage.

Provided is a method for manufacturing a long-life brewed alcoholic beverage by a filtration process with the use of a porous membrane involving a washing step, whereby a high tolerance (chemical tolerance) to a washing solution (a chemical solution) and a good filtration performance are achieved. A method for ma manufacturing a second brewed alcoholic beverage which includes: a filtration step for passing a first brewed alcoholic beverage, which contains a yeast and a high-molecular substance or sediment component produced through fermentation by the yeast, through a porous membrane, which is formed of a resin having a three-dimensional network structure, to thereby separate the second brewed alcoholic beverage from the yeast; and a washing step for passing a washing solution through the porous membrane or immersing the porous membrane in the washing solution to thereby wash the inside of the porous membrane.

A stack of ion exchange membranes suitable for water purification comprising a plurality of anion exchange membranes (AEMs) and a plurality of cation exchange membranes (CEMs), wherein the colour properties of the AEMs are visibly different to the colour properties of the CEMs. The invention also provides a process for making membrane stacks in which the likelihood of there being two consecutive membranes of like charge is reduced. Furthermore, it is easy to identify whether there are two consecutive membranes of like charge present in the stacks.

Methods and devices for use in removing biogenic amines from wine or other liquids are described. The methods and devices use a cation exchange resin and/or molecularly imprinted medium selective for amines to remove the amines from the wine or other liquid at the point of use.

A method of producing beer having a tailored flavour profile is provided comprising the successive steps of: (a) fermenting wort containing fermentable sugars with yeast to produce beer containing 1-10 vol. % ethanol and flavour substances diacetyl; acetaldehyde; dimethyl sulfide; ethyl acetate; isoamyl acetate; ethyl valerate; ethyl hexanoate; iso-amyl alcohol and 2-methylbutan-1-ol; (b) contacting the fermenting wort or beer with porous adsorbent particles, selectively adsorbing the beer flavour esters ethyl acetate, ethyl hexanoate, ethyl valerate and isoamyl acetate; (c) separating the adsorbent particles; (d) desorbing a portion of the beer flavour esters from the adsorbent particles; and (e) adding a fraction of the desorbed beer flavour esters to the flavour adjusted beer or to another beer, wherein the amount of beer flavour esters added is 5-95 wt. % of the amount of beer flavour esters removed by the adsorbent particles.

Beverage filtration device including a lid body having an internal housing configured to hold an ion exchange resin-filed cartridge therein having a connection end and a top end having an opening therein, and, stem body having a cap region, collar, beverage conduit and stem air tube. The cap region couples to the connection end of the lid body to form a liquid-tight seal coupling there-between. A collar wall first portion fits inside a beverage mouth container and a second portion located outside of the mouth. The beverage conduit spans the collar, a first conduit opening open to the coupling between the cap region and the connection end and a second conduit open to a container interior. The stem body air tube extends through the collar, a proximal opening of the stem body air tube opens to an air vent hole located in the second portion of the collar wall, and, a distal opening of the stem body air tube opens to the container interior.

A process for obtaining a concentrated flavour mixture from a malt-based beverage, the process comprising: —providing a malt-based fermented liquid; —subjecting the malt-based fermented liquid to a CO.sub.2 or N.sub.2-stripping step or, at least partially, degassing the malt-based liquid, thereby creating a gas stream comprising volatile flavour components; —collecting the gas stream comprising volatile flavour components; and —separating, by a carbon dioxide or N.sub.2 scrubber, at least partially, the CO.sub.2 or N.sub.2 in the gas stream from the volatile flavour components, obtaining a concentrated volatile flavour fraction; —collecting said volatile flavour fraction and packaging the volatile flavour fraction.
