Fermentation of ice apple wine from freeze-concentrated Fuji apple juice to 36 °Brix was carried out using Saccharomyces cerevisiae SS89, a sugar-tolerant wine yeast strain. The characteristics of the fermentation and the properties of ice apple wine were compared with those of S. cerevisiae W-3, an industrial wine yeast that was used as a control in this study. During the fermentation, the alcohol content increased more rapidly by S. cerevisiae SS89 together with the decrease of the soluble solid content, compared to S. cerevisiae W-3. It reached 12% (v/v) after 15 days of fermentation by S. cerevisiae SS89 (12.4%, v/v) and 21 days by S. cerevisiae W-3 (12.6%, v/v). The soluble solid contents of the SS89 and W-3 wines were 24.0 and 23.6 °Brix, respectively. Lactic acid was detected at the highest level, followed by malic aid, among the organic acids in both wines. No big differences in the organic acid contents were observed based on the strains. In the SS89 wine, higher levels of methanol, propanol, butanol, and isoamyl alcohol were detected, together with a lower isobutanol content, compared with the W-3 wine. The SS89 wine showed higher level of intensity as well as higher Hunter's L and b color values compared to the W-3 wine. In the sensory evaluation, similar scores in color, flavor, taste, and overall preference were obtained in the two wines. Therefore, S. cerevisiae SS89 was thought to be useful for the rapid fermentation of ice apple wine.

국산 캠벨 얼리 포도과즙을 36 로 동결농축한 후 국산 포도로부터 분리된S. cerevisiae S13, D8 균주를 이용하여 아이스와인의 발효를 행하면서 대조균주인 S. cerevisiae Fermivin과 발효특성을 비교하였다. 발효 중 S13과 D8의 경우 Fermivin보다 당도가 다소 빠르게 감소하였으며 빠른 알코올 생성을 보였다. 발효 종료 시점인 9일 후의 알코올 농도는 D8이 15.2%, S13은 14.0%, Fermivin은 12
