We study the effects of fermention condtion on sensory quality and chemical composition of Dancong tea wine.The results show that the content of alcohol is from 6.8% to 9.1% in the dancong tea wine;the content of total carbohydrate is less than 132.2g/L;the content of total acid is from 2.87 to 3.48g/L.For the best fermenttion conditions,extracting temperature should be controlled between 50℃and 75℃,the ratio of yeast to tea extraction should be 1: 30,the fermentation temperature should be kept around 30 ℃....
