Abstract: A device for measuring the temperature of an open bottle of wine which combines a thermometer and a protective container for storage of the thermometer. The container top is designed to receive the thermometer indicator head and is further adapted to be used with the thermometer to seal the bottle opening when the thermometer is in use. The thermometer's temperature indicator scale is divided into color coded segments, each segment the color of wine that should be served at temperatures within the range corresponding to the segment.
