The invention discloses a 
processing process of 
green tea capable of being brewed by cold water. The 
processing process comprises the steps of fresh leaf picking, low-temperature 
quick freezing, 
microwave thawing water removing, first-step 
roasting leaf stir-frying, twisting, cooling, piling slight 
fermentation and 
drying, wherein in the low-temperature 
quick freezing step, picked fresh leaves are fast conveyed into a freezer and are fast frozen for 24 to 48 hours at -20 DEG C; in the 
microwave thawing water removing step, the fast frozen fresh leaves are flatly paved onto a conveying belt of a 
microwave water removing 
machine, the thickness is 2 to 4cm, and the microwave water removing 
machine is started for performing microwave water removing for 5 to 8 minutes until the 
water content of the fresh leaves is 70 to 75 percent; and in the piling slight 
fermentation step, the cooled twisted leaves are firstly subjected to piling, the weight in each 
pile is 30kg, each tea 
pile is sealed and covered by 
preservative films after the piling, and the twisted leaves are subjected to slight 
fermentation for 1 hours in sealed environment. The 
processing process has the advantages that the tippy quantity of the prepared tea is great, the taste is mellow, the mouth feeling is good, in addition, the 
cell fragmentation degree is high, and the fragmentation is sufficient, so the 
green tea is suitable for being brewed by the cold water; and the processing process is simple.
