The invention discloses a wine decocting method adopted during manual brewing of yellow rice wine and a wine decocting device for implementing the wine decocting method. The wine decocting method comprises the following steps: firstly preheating yellow rice wine sake, then carrying out PEF (pulsed electric field) sterilization so that the wine decocting purpose is achieved, and finally, placing the processed yellow rice wine into a wine jar, and carrying out sealed ageing, wherein the field intensity of the pulsed electric field is 20-40 kV/cm, and the treatment time is 180-200 [mu] s. The wine decocting device comprises a pump and a PEF processing chamber, wherein the pump is connected to an entrance of the PEF processing chamber, the yellow rice wine sake is added into the PEF processing chamber through the pump, and an exit of the PEF processing chamber is connected to the wine jar. With the adoption of the method and the device provided by the invention, the energy consumption of the traditional wine decocting method can be reduced, and meanwhile, some functional substances in the yellow rice wine sake can be protected, so that the ageing process is perfect.
