The present invention relates to drink-stirring device for stirring or mixing liquid and/or powdered ingredients with liquid in a drinking vessel (4), the liquid being supplied from above through the stirring device to an outlet tube which conducts at least one liquid jet towards the interior of the drinking vessel. The liquid is supplied through an outlet tube (64) which is rotatably attached to the device and is associated to an external, magnetic member (82). The electromagnet arrangement is arranged outside or at distance of the magnetic member for creating a variable magnetic field configured to move the tube (64) in rotation, so that the emerging liquid jet can be given a corresponding centrifugal effect.
