A wine decanter includes a housing and a variation magnetic field generator, where the variation magnetic field generator is configured to generate a variation magnetic field, and the variation magnetic field generator generates the variation magnetic field, so that a movement component that can sense a magnetic field moves in wine to make the wine move, thereby increasing contact between the wine and air. The decanting device includes a wine container, a movement component, and the decanter according to any one of the foregoing, where the movement component is placed inside the wine container, the decanter is connected to the movement component by using a magnetic field, and the decanter generates a variation magnetic field to drive the movement component to perform decanting. The structure of the decanter is simplified, thereby facilitating miniaturization, and making it convenient to carry the decanter, and also reducing noises.
