Abstract
A beverage package has a sealed container 1 containing beer 11 having gas in solution and forming a headspace 16 containing gas at pressure greater than atmospheric. A hollow insert 7 is located in the container and is responsive to a pressure differential developed on opening the top 5 of the container to inject beer and/or gas therefrom into the beer 11 whereby to liberate gas 17 from solution and form froth in the headspace 16. A baffle plate 12 on the insert 7 restrains the liberation of gas 17 to a minor proporation of the volume of beer 11 so that when the beer is poured into a glass, gas can evolve naturally from the beer to produce 'sparkle'. As an alternative to the beer and/or gas injection bubble initiation, gas from solution in the minor proporation of the volume of beer may be liberated by contact of that beer with a bubble initiating material.
