Methods The changes of 20 kinds of main compositions in 52° liquor of New production and storage of 0.5-30 years along with the change of age were systematically studied, and its pH value and conductivity were analyzed. The samples were analyzed by gas chromatography and quantitative by internal standard method. Results The relations between storage time and total acid, total ester and various alcohols were revealed in this study
