Claim:
1. A closure for a beverage keg, the closure comprising a housing defining: an inlet for admitting a pressurised gas into a headspace of a beverage keg; and a venting hole separate from the inlet, the venting hole communicating with a gas vent path between the headspace of the keg and an exterior of the closure; the closure further comprising a barrier for sealing the venting hole; wherein, when fitted to the keg, the closure is configured to be switchable from: an unvented configuration in which the barrier seals the venting hole so that the closure is able to retain a pressurised gas within the keg; to a vented configuration in which the venting hole is no longer sealed by the barrier so that a pressurised gas in the headspace of the keg can escape along the gas vent path via the venting hole to the exterior of the closure; thereby permanently depressurising the keg, wherein the barrier is engaged to the housing defining the venting hole when the closure is in the unvented configuration, and the barrier is arranged to be dislodged from its engagement with the housing defining the venting hole so as to switch the closure to the vented configuration.
