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.

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.

The present disclosure relates to a filter designed to purify alcohol, particularly spirits, and more specifically to a reusable multi stage spirit filter. The filter unit is adapted to connect with two fluid containers, the filter adapted receive commercial filter cartridges of the be a refillable filter. Typical filter materials being selected from activated charcoal or carbon, or an ion exchange resin. The reusable filter that can be repeatedly used to clean or polish spirits to remove the impurities thereby improving the taste of spirits.

A device including a lid body including a connection end, a top end having an opening therein, a pouring spout body encompassing the opening, and, a stem body including an internal housing configured to hold an ion exchange resin-filed cartridge therein, a cap region, collar, a beverage conduit, and a stem body air tube. The cap region configured to couple to the connection end of the lid body to thereby form a first liquid-tight seal coupling between the connection end of the lid body and a top end of the ion exchange resin-filed cartridge, and, form a second a liquid-tight seal coupling between a base region of the internal housing and a bottom end of the ion exchange resin-filed cartridge. First and second collar wall portions sized to fit inside a mouth of a beverage container and to be located outside of the mouth. The beverage conduit spans the collar with a first and second openings to the base region and an interior of the beverage container. The stem body air tube extends through the collar with proximal and distal openings to an air vent hole located in the second portion of the collar wall and to the interior of the beverage container.
