Bottle size used in Great Britain for sparkling wine. An English pint contains exactly 0.568 litres, which is one eighth of the English gallon. The English pint is also called Imperial pint, where Imperial is used as a designation for the English standard as opposed to the US standard. However, Imperial Pint must not be confused with the bottle size Impériale. See also a list of all bottle designations under Bottles and generally under Wine Vessels.
