ABSTRACT A method of packaging a beverage and a package structure has a cylindrical tube 1 over an end 3 of which is located a partition wall 2 having a restricted orifice 6. A closure wall 7 is located over the partition wall 2 and both walls are sealed, for example by crimping, to the rim of the tube 1. A primary chamber 4 is formed within the tube and a secondary chamber 8 is formed between the partition wall 2 and closure wall 7 which chambers communicate through the orifice 6. Chamber 4 is charged with beverage 11 containing gas in solution and sealed with an end wall 12 crimped to the rim 9 of the tube 1. Prior to sealing the chamber 9 is dosed with liquid nitrogen or carbon dioxide so that headspace 13 in that chamber is pressurised. The package adjusts to a state of equilibrium in which beverage flows into the secondary chamber 8 to form a headspace 14 therein. Upon opening of the package with a pull tag 15 a pressure differential between the headspace 14 and 13 causes beverage and/or gas in the chamber 8 to be ejected through the orifice 6 into the beverage 11 and thereby gas in solution in the beverage to be liberated and form, or assist in the formation of, a head of froth on the beverage.
