Abstract: The new wine needs to require aging processing to achieve the mature. The conventional aging treatment includes temperature and humidity control, shock prevention, light avoidance, etc. Its flavor and color after aging are significantly improved, but the method has high labor cost, long storage time, and the price is high after aging. Early research found that the wine under the condition of the alternating substation field treatment, the wine body color and taste will change, and different electric field intensity and processing time will lead to obvious differences. In order to determine the suitable aging conditions of wine under the electric field conditions, the composition and contents of the wine control the changes under specific temperature and humidity conditions. Final treatment conditions for electric field: 5 days at 100 V~400 V at 50 Hz.
