This study was conducted to investigate the physicochemical and sensory changes of 6 kinds of commercial Makgeolli (A, B, C, D, E, and F) during storage at 4±1℃ for 30 days. The initial pH was 3.50~4.23, but it increased to 3.65~4.37 by the end of the storage period (p〈0.05) There were no significant differences in titratable acidity between the beginning and end of the storage period. The reducing sugar content of A and B increased, whereas C, D, E, and F decreased with increasing storage time. A decrease in lightness (L values) was observed in all samples with increasing storage time (p〈0.05). The alcohol content increased from beginning values of 5.90~6.10% to ending values of 6.30~7.35% at the end of storage, of which sample B exhibited the highest value. A sensory evaluation test revealed that the overall acceptability of samples A, B, D, and E were still within acceptable limits, but samples C and F showed undesirable changes during 30 days of storage at 4℃.
