ABSTRACT:
Method of packaging a beverage having gas in a solution in which an open topped container is charged with the beverage therethough. The container is purged of air and pressurized with gas selected from carbon dioxide, nitrogen or other inert gas and a partition having a restricted orifice is located over the beverage and sealed to the container to form a primary beverage chamber. A closure wall is located over the partition and sealed thereto and to the container to form with the partition a secondary chamber. The primary and secondary chambers communicate with each other through the restricted orifice. The assembly is inverted so that beverage from the primary chamber enters the secondary chamber and a primary headspace is formed in the primary chamber and a secondary headspace in the secondary chamber. Both headspaces are at a pressure greater than atmospheric so that upon opening the container exposing the primary chamber to atmosphere, beverage and/or gas in the secondary chamber is ejected into the beverage in the primary chamber to develop a head of froth.
Pressurization of the container with the selected gas is preferably by dosing with the gas in liquid form before the closure wall is fitted and sealed to the container and either before or after the partition has been fitted to the container.
