Abstract
A spirit chilling apparatus comprising a drink chilling tube (,) concentric within an insulated container (,) filled with a constant boiling cryogen (,), such as acetone and solid carbon dioxide or similar azeotropic mixture. The innertube (,) is held in relatively poor thermal contact with the vessel (,) containing the liquid so that over a period of time it will adopt the temperature of the liquid (,) but when a measure of spirit is poured through it the specific heat of the tube (,) will be sufficient to result in a net temperature of −5° C. for both the spirit and the tube (,), the heat flow from the surrounding vessel (,) being insufficient to materially affect this. If the tube (,) is left in place it will again cool to the previous temperature so that a further measure of spirit can be cooled.
