In the fermentation of Yulmoo Mulkimchi, various ratios of Yulmoo to water (l/l.14, l/l.5, 1/2, l/2.75, 1/4) were prepared and fermented at 4$^{\circ}C$, 15$^{\circ}C$, 25$^{\circ}C$ for up to 10 days. According to the fermentation time, the pH, acidity, total vitamin C content and microbial growth in Mulkimchi samples were determined together with sensory evaluation. Fermentation temperature on water addition ratio didn't show any difference in pH and microbial growth of Mulkimchi. However, low ratio of water resulted in high acidity and vitamin C content in Mulkimchi. In terms of acid odor and acid taste, the least water addition (l/l.4) sample was significantly strong than those of other samples. The ratio of Yulmoo to water, l/2 showed the highest overall sensorial acceptability and followed by l/l.5, l/l.4, l/2.75 and 1/4 samples. It was found that the content of vitamin C and acid taste of Mulkimchi have correlation with its acceptability.
