The present invention discloses a quick aging method for Liubao tea, comprising the following steps: arranging Liubao tea to be aired and aged in a closed container; charging proper oxygen (the concentration is from 30% to 100%) after vacuuming; and radiating (the dosage is from 4kGy to 20kGy) by <60>Co-gamma ray under the condition of normal temperature and normal pressure. The method has the advantages that the oxygen is charged for quickening the oxidation of polyphenol compounds in tea; the tea is aged evenly and has stable quality; the aging time is largely shortened; moreover, the sanitary condition of the tea is ensured; and the <60>Co-gamma ray can effectively kill pollution microbes so that the content of the pollution microbes in the tea is lower than commodity inspection standards, thereby effectively solving the problem of influencing the output of Liubao tea due to super-standard microbes and ensuring product quality and yield raise. After the Liubao tea is treated by the new quick aging technology, the saline degree can be reduced instantly, in addition, red teat water and smooth and sweet taste can be achieved.
