After passing alcoholic liquors 20 through an HSO<SUB>3 </SUB>type strongly basic anion exchange resin layer 14 , or after adding an HSO<SUB>3 </SUB>salt to alcoholic liquors; the alcoholic liquors are passed through a mixed bed layer 18 containing of an H type strongly acidic cation exchange resin and a free base type weakly basic anion exchange resin, or the alcoholic liquors are successively passed through an H type strongly acidic cation exchange resin layer and a free base type weakly basic anion exchange resin layer. According to this way, it is possible to remove aldehydes and inorganic salts from alcoholic liquors such as brewed alcoholic liquors and distilled alcoholic liquors, while strongly retaining a peculiar fragrance or retaining a manneristic flavor.
