<p>A beverage (4) in initially sealed container (2) for example a bottle with a transparent wall comprises a water content and a dissolved gas content. The beverage may be alcoholic for example a lager or a flavoured alcoholic beverage or alco-pop. In the sealed container (2) the beverage (4) is cooled to a temperature below the freezing point of water at ambient atmospheric pressure. The cooled beverage is served in the container (2) which is opened to expose the beverage to ambient atmospheric pressure. Some of the dissolved gas bubbles out of the beverage. Such bubbles form nucleation sites which promote formation of slushy ice from some of the water content of the beverage, the formed ice expanding as a mass (12d) from the top of the container.</p> |
