The invention discloses a brewing device for tea wine production, and relates to the technical field of tea wine brewing. In order to solve the problems that in the prior art, when tea wine is brewed,that internal liquid is heated uniformly cannot be guaranteed, and the outside lacks heat preservation measures, the following scheme is provided. The brewing device comprises a fermentation barrel,wherein the fermentation barrel is fixedly sleeved with a heat preservation water storage cover, the heat preservation water storage cover is internally and movably sleeved with a water flow circulating mechanism, the fermentation barrel is internally and movably sleeved with a piston, the top of the piston is rotationally connected with a fixed pipe, one side of the bottom of the fixed pipe is fixedly connected with a water suction pipe, the top of the fermentation barrel is fixedly connected with a sealing cover, the bottom of the fermentation barrel is fixedly connected with a positioning mechanism, and a movable plate is arranged at the top of the sealing cover. The inside and outside of the fermentation barrel are heated uniformly, high-quality and efficient fermentation is facilitated, the discharging direction can be adjusted, sediment in the barrel can be conveniently removed, and the device is rapid and saves labor.
