Abstract: One bud four five leaves of the tea tree variety E tea No. 10 popularized in Hubei Province were selected as the raw materials. An orthogonal optimization experiment was conducted on the key process of Qingzhuan tea, pile-fermentation, with three factors (tea dhool moisture content, temperature, and humidity) at three levels. The results showed that the moisture content of the tea dhool and the humidity of the pile-fermentation had great influence on the quality of Qingzhuan tea; the optimal parameters were as follows: Moisture content of the tea dhool(40%), humidity (70%) in the fermentation environment, and temperature (45 ℃) in the fermentation environment.
