Abstract: Natural aging of Baijiu have the problems of long production cycle, large occupation area and high investment cost. Thus, artificial aging technology of Baijiu has received extensive attention. At present, the common artificial aging technologies of Baijiu include physical aging, chemical aging and biological aging, among which the application potential of physical aging and biological aging is relatively large. The application of these technologies can shorten storage time significantly, improve Baijiu quality and lower production costs. In this paper, Baijiu aging mechanism, storage conditions and the research advances of artificial aging technology are summarized and the different aging techniques and their application prospects are analyzed and compared. The purpose of this paper is to provide reference for the research of Baijiu artificial aging in the future.
