A beverage package as described comprising a two piece can (10) having fitted therein a secondary chamber (14) for trapping a volume of gas under pressure which when the can is broached just prior to pouring (or consuming the beverage (12) directly from the can), is emitted from the chamber via a small orifice (16) in the wall thereof. The secondary chamber includes an elongate tube (22), extending from the capsule in an upward sense, which terminates just below the lid (26) of the can. An opening (28) in the wall of the tube communicates with the headspace above the beverage in the can. A one way valve (24) is provided in the tube, adapted to prevent the ingress of beverage. The small orifice (16) in the wall of the secondary chamber may be closed by a bung of gelatine which will melt at a given temperature. Alternatively a bursting disc is described as being fitted, which only requires the pressure drop on broaching the can to burst open the disc and permit the contents of the housing to issue into the can and begin the process of forming the bubbles.
