The results showed that the fermentation degree was amended and raised when the alcoholicity was 8% and the proportion of persimmon and cornstarch was 3:1;and that sugar content reduced and acidity raised. In the same time, when the added content of amylase was 0.3%,amyloglucosidase was 0.4%,active dry yeast was 0.2%,inoculum size of vinegar bacteria was 10% in manufacturing, the fine clear persimmon vinegar with 3.54g/100ml acidity was produced which the color was brown red, acidity was mild and aroma was delicate.
