The invention relates to a container such as a wine glass, tumbler, long drinks glass or other cold drink vessel/receptacle or dispenser that is provided with double side walls which form a cavity therebetween. The base of the container portion which receives the liquid is single walled and can be provided in contact or near contact with a cooling medium. The cooling medium includes a capsule of a cooling compound. The cooling medium can be selectively located on the container to provide a cooling effect on the liquid held therein. Typically the capsule is biased towards the base of the container by biasing means located within the housing of the cooling medium so as to ensure the liquid in the container remains chilled whilst being consumed.
