It showed that the yeast KD had higher fermentation capacity, gentle fermentation speed, and the produced kiwi fruit wine was clear and transparent with light yellow color and typical kiwi fruit aroma and wine-alcohol bouquet. Furthermore, the produced kiwi fruit wine had high alcohol content to 10.5 %vol, high vitamin C content to 0.94 g/L and low content of reducing sugar, total acid and volatility acid. 48 aroma substances in total were identified including esters (19 kinds, 34.65 %), higher alcohols(5 kinds,15.38 %), fatty acids(6 kinds,13.30 %), and micro-content of alkyls, aldehydes and ketones, which accounted for 97.33 % of total peak area. Such yeast was suitable for kiwi fruit wine brewing. Tran. by YUE Yang
