Abstract: A method of treating an beverage, comprising exposing a beverage to an ion exchange matrix that includes a mixture of cation exchange beads and anion exchange beads each capable of binding to one or more cationic or anionic constituents present in the beverage and thereby reduce concentrations of the one or more cationic or anionic constituents in the beverage and capable of maintaining a pH of the beverage within ±0.5 pH units of the beverage's pretreatment pH value. The cationic or anionic constituents have a noxious effect on humans and the cation exchange beads include a cationic mineral form and the anion exchange beads include a chloride mineral form.

Abstract: A treated wine beverage prepared by a process including exposing a pretreated wine 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 wine, reducing concentrations of the one or more cationic or anionic constituents in the wine and maintaining a conductivity value of the treated wine equal to or greater than the pretreated wine beverage's conductivity value.

Abstract: 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.
