The invention belongs to the technical field of liquor aging and particularly relates to a liquor aging device. The liquor aging device comprises an aging barrel externally wound with an electromagnetic induction coil, wherein an alternating current power supply is connected to the end part of the electromagnetic induction coil, a stirring rod is arranged in the aging barrel, an interlayer is arranged in the middle of the bottom of the aging barrel, and a magnet is arranged in the interlayer; the stirring rod is a conductor and is externally sleeved by a heat-conducting stirring sleeve, and anion oxidizing particles are arranged between the stirring rod and the stirring sleeve; and a chassis is connected to the bottom end of the stirring rod in a rotating way, stirring blades are fixedly mounted on the chassis, and a filtering hole with the diameter smaller than diameters of the anion oxidizing particles is formed in the outer wall of the stirring sleeve. According to the liquor aging device, the problem that the aging effect is poor when air is directly introduced into the liquor is solved.
