Glutinous rice Sikhye was fermented by Saccharomyces cerevisiae for 10 day at 29℃. Fermentable sugars such as maltose and maltotriose in glutinous rice Sikhye were converted into ethanol by the yeast, but limit dextrin was remained after the fermentation. Fermentation rate of sugars in glutinous rice Sikhye was lower than that in rice Sikhye. Glutinous rice Sikhye wine was found to contain 7.3% of limit dextrin, 3.6% of ethanol, 0.35μ㏖/ml of amino acid, 100㎍/ml of protein, and the acidity of the Sikhye showed 3.2, respectively, and its pH was 3.23. Limit dextrin in glutinous rice Sikhye wine showed both signal of α-1, 4- and α-1, 6- glucosidic linkage with its estimation ratio of 5.6:1 by ^1H-NMR analysis. The taste of rice Sikhye wine was similar that of wine.
