Apparatus for cooling and retarding an increase in the temperature of a liquid contained in a vessel. The apparatus includes a base for substantially occupying the lower interior of liquid containing vessel and a cooling body for upward projection from the base so that when the base is placed in the vessel the cooling body projects upwardly therefrom for submersion in the liquid. The cooling body comprises a sealed container substantially filled with a slow-to-freeze, slow-to-thaw gelatinous material which may be frozen prior to submersion in the liquid.
