Makgeolli is a traditional rice wine favored by the general public in Korea. This study investigated the fermentation and sensory characteristics of using wild yeast strains for brewing makgeolli. A non-Saccharomyces cerevisiae strain was isolated from nuruk and termed Y197-13. It showed 98% similarity to Pichia anomala and had an optimal growth temperature of $25^{\circ}C$. Makgeolli was manufactured using koji, jinju nuruk, and improved nuruk as fermentation agents. Y197-13 makgeolli brewed with koji had alcohol and solids contents of 11.1% and 13.9%, respectively. Sweet sensory characteristics were attributed to residual sugars in makgeolli with 6% alcohol. The makgeolli had a fresh sour taste and carbonated taste. Volatile component analysis showed the isoamyl alcohol, phenylethyl alcohol, isoamyl acetate, and fatty acid, including ethyl oleate and ethyl linoleate, relative peak area was higher in Y197-13 makgeolli than in makgeolli with Saccharomyces cerevisiae. These results suggest the wild yeast, Y197-13, as a candidate for brewing makgeolli.

Li was a sweet beverage containing $2{\sim}3$ percents ethyl alcohol made from malt by spontaneous fermentation from ancient custom to fifteenth century. Li was changed to the rice wine being a sweet beverage of low alcohol content using nuruk as starter and the sikhae which is non-alcoholic fermented beverage. Li was made for drinking and ceremony in Korea, China and Japan. It disappeared from the beverage items along with its method of manufacture from malt, but in Korean had made Li using nuruk until recent. We made Li according to Book of Imwon-Keongjae Ji (The book of country economy) methods for reappearance of Li. Fermentation characteristics for the production of Li with Saccharomyces cerevisiae, Saccharomyces bayanus and Saccharomyces sake were investigated. Among the yeast strains tested, Li fermented with S. sake showed higher alcohol production. Total sugar decreased considerably during the whole period of fermentation(30 hours), while ethyl alcohol content increased at $2.98{\sim}3.52%$. As the fermentation progressed, the pH decreased until the 30 hours of fermentation, while total acid increased during the same period. In fermentation of 36 hours, Li consisted of about $2.98{\sim}3.52%$ of alcohol content, $5.3{\sim}6.0%$ of total sugar, $1.45{\sim}2.21mg%$ of reducing sugar and total acidity were reached up to $24.4{\sim}29.5mg%$ for Li manufactured with S. cerevisiea sake, S. bayanus and S. sake.

This study was conducted to investigate the preference and consumption status of non-alcohol and alcohol beverages of Korean and Chinese university students in the Jeonbuk area. Self-administered questionnaires were collected from 241 Korean and 198 Chinese students. Statistical data analysis was completed using SPSS v. 12.0. 'Water' was the most commonly consumed non-alcohol beverages by all Korean and Chinese students. The intake frequency of 'carbonated drink' (p<.001), 'fruits/vegetable juice' (p<.05), and 'vinegar drink' (p<.01) of Chinese male students was significantly higher than the Korean male students. The intake frequency of 'ionic drink' (p<.001; p<.01) of Korean male and female students was significantly higher than the Chinese male and female students. The intake frequency of 'fruits/vegetable juice' (p<.001), 'milk' (p<.01), and 'soymilk' (p<.05) of Chinese female students was higher than the Korean female students. For the choosing the non-alcohol beverages, the Chinese female students were more health-oriented than the Korean female students (p<.01). 'Beer' was the most commonly consumed alcohol beverages by the Korean male and female and Chinese male students whereas 'Wine' was the most commonly consumed alcohol beverages by the Chinese female students. The intake frequency of 'Soju' of Korean male (p<.001) and female (p<.001) students was higher than the Chinese male and female students. The intake frequency of 'Wine' of Chinese male (p<.05) and female (p<.001) students higher than the Korean male and female students. Compared with the Chinese female students, the Korean female students more funds have to spend, in order to buy alcohol beverages (p<.01). More 81% of the Korean male and 80% of the female students reported drinking alcohol in 'beer house' whereas 78% of the Chinese male and 65% of female students drunken the alcohol in the 'beer house' or at 'home' (p<.01; p<.001). In conclusion, a practically and foreigner-friendly alcohol policies of university should be devised to reduce the alcohol consumption of students and related problems.

Makgeolli is a traditional cloudy-white Korean rice wine with an alcohol content of 6~7%. The present study investigated the morphological characteristics, carbon-utilizing ability, fatty acid composition, alcohol resistance, glucose tolerance, and flocculence of Saccharomyces cerevisiae Y98-5 and Pichia anomala Y197-13, non-S. cerevisiae isolated from Nuruk, which is used in brewing Makgeolli. Similar morphological characteristics were observed for both isolated wild yeast strains; and the carbon source assimilation of Y197-13 differed from that of other P. anomala strains. Strain Y197-13 was negative for D-trehalose, mannitol, arbutin, I-erythritol, and succinic acid. The major cellular fatty acids of strain Y197-13 included C18:2n6c (33.94%), C18:1n9c (26.97%) and C16:0 (20.57%). Strain Y197-13 was Crabtree-negative, with 60% cell viability at 12% (v/v) ethanol. The flocculation level of strain Y197-13 was 8.38%, resulting in its classification as a non-flocculent yeast.
