1. A carbonator for producing carbonated beverage comprising:
a first connector, for a gas-outlet of a CO2-container, and with a CO2-valve operable between a closed state and an open state in which CO2-gas may be introduced from the gas-outlet of the CO2-container into the CO2-valve;
a second connector, for a mouth of a beverage container, and with a dissolver nozzle, for introducing CO2-gas into the beverage container, connected to the CO2-valve;
a venting valve connected to the second connector and operable between a closed state and an open state in which excess CO2-gas may be led out from the beverage container through the venting valve;
an operating mechanism configured to operate the CO2-valve and the venting valve between open and closed states; and
a manipulator, coupled to the operating mechanism, for allowing a person to operate the operating mechanism between:
a start mode in which the venting valve is open and the CO2-valve is closed, and
an end mode in which the CO2-valve is open and the venting valve is closed,
wherein the operating mechanism is configured to be set in an intermediate mode, between the start mode and the end mode in which both the venting valve and the CO2-valve are closed.
