1. In combination with an open wine vessel and a ferromagnetic stir bar located inside said vessel, an automatic wine stirrer comprising:

  • a housing;

    a fan assembly operatively mounted within said housing, and comprising a rotatable hub, a plurality of fan blades attached to said hub, and an electric motor;

    at least one magnet carried by said fan assembly and adapted for being magnetically connected to said stir bar; and

    means for electronically controlling intermittent rotation of said fan assembly, said means configured to control said fan assembly to spin said stir bar intermittently between a run condition sufficient for substantially swirling the wine contained in said wine vessel and a substantially stopped condition less than 20 RPM, whereby;

    (i) when said fan assembly is in the substantially stopped condition, said magnet attracts and holds said stir bar located inside said wine vessel, and(ii) when said fan assembly moves to the run condition, said magnet rotates relative to said housing thereby rotating said stir bar and substantially swirling the wine contained in said wine vessel.
