Abstract:Baijiu plays a crucial role in the brewing process.However，the natural aging of baijiu reduces production efficiency and increases investment costs.Thus，artificial aging technology has been used to quickly age the baijiu body.To date，there have been many studies on physical aging technology，and the latter have demonstrated a shortening of aging time and improvements in baijiu quality.This paper summarized the two aspects of baijiu aging mechanisms and existing technology，hoping to provide a theoretical reference for the optimization of the artificial aging technology of baijiu.
