The invention discloses a method for accelerating aging of vinegar with ultrasonic wave, and belongs to the technical field of vinegar aging acceleration. The method comprises the following steps: storing newly brewed vinegar and ethanol which accounts for 0.55-0.85% of the volume of the vinegar in a container, sealing the mount of the container, keeping the temperature inside the container to be 30-40 DEG C, and applying low-frequency high-intensity ultrasonic wave with the frequency of 18-29 KHz and the ultrasonic density of 40-60 W/100mL (the volume ratio of the ultrasonic power to the aging accelerated vinegar) to the vinegar in the container for 60-80 minutes. By adoption of the method, the aging effect of 3-5 years of natural aging can be achieved within 60-80 minutes, the aging time is greatly shortened, and the aging acceleration effect is remarkable.
