Oxidized is a flavor term to describe a beverage which has suffered excessive oxidation. During oxidation, beverages lose their original freshness and take on a darker color, eventually becoming quite brown. The fruity flavor is replaced by one reminiscent of paper or "vegetable soup," later becoming nutty or maple-like and, finally, meat-like and dead.
