A method of treating wine, comprising: after production and bottling of the wine, exposing the wine to an ion exchange matrix that includes a mixture of cation exchange media and anion exchange media that comprise: (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 wine; reducing concentration of the one or more cationic or anionic constituents in the wine; and maintaining a conductivity of the wine equal to or greater than the wine's pretreatment conductivity value.
