The removal of excessive acids and minerals with ion-exchange resins was undertaken with 2 l of grape must (Delaware).The must was passed through 1〜3 columns (Table 1), each of which was filled with 100 cc of anion- or cation-exchange resin, and then supplemented with a small amount (30% by volume) of untreated must.fermentation of must obtained through the double bed system required comparatively long time but that by the single bed system (removal of anion only) was not affected. The wines obtained from the treated must clarified rapidly and possessed the proper amounts of extract and sugar contents and also the concentration of glycerol and fusel oil was relatively low, so that ion-exchange treatment of must conferred the desirable influence upon the wines.The results of the test for taste indicate that the must treated with double bed system (Table 1 : A) produces a more excellent wine than the others.
