This study was carried out to evaluate the basic characteristics of red wine processed from ‘Cheongsan (Vitis amurensis)’ grape cultivar. In order to compare the quality of ‘Cheongsan’ red wine, ‘Campbell Early’ and ‘Muscat Bailey A, MBA’ red wines were also utilized for this study. The pH of the red wines produced from ‘Cheongsan’, ‘Campbell Early’ and ‘MBA’ were 3.1, 3.6 and 4.0, respectively. Tannin, polyphenol, and anthocyanin contents of the ‘Cheongsan’ red wine were 2,939 mg/L, 1,516.2 mg/ L, and 1,882.4 mg/L, respectively. These values were about twice those of ‘Campbell Early’ and ‘MBA’ red wines. The antioxidant level of ‘Cheongsan’ red wine was found to be 5,413.9 mg/L, which was also two times higher than 'Campbell Early' and 'MBA' red wines. Although the acidity of ‘Cheongsan’ red wine is relatively high, ‘Cheongsan’ red wine contains a lot of tannin, matures over an extended period of time and has excellent antioxidant properties. These results indicated that 'Chengsan' grape could be an excellent source for production of high quality red wine.
