This invention provides a wine aging device. At the new wine supply end, the wine to be aged is input into the aging loop pipeline. A circulating motor circulates the wine within the loop pipeline, allowing it to pass through a temperature-regulating tank and a wine molecule cutting device. The temperature-regulating tank simulates the temperature differences of the four seasons, adjusting the temperature of the flowing wine to match the temperature of different seasons, thereby accelerating fermentation. Subsequently, as the wine passes through the wine molecule cutting device, large wine molecules are broken down into smaller molecules until aging is complete. Afterward, the wine output end receives the aged wine, while the new wine supply end inputs another wine to be aged into the aging loop pipeline. This cyclical process promotes and accelerates fermentation, producing an aging and softening effect while simultaneously breaking down undesirable flavors. This invention belongs to the technical field of brewing equipment.
