a compressed-gas cartridge accepted within the cap body, the compressed-gas cartridge configured to provide gas under pressure;
an external straw extending from the cap body, the external straw having an internal passageway for delivering a beverage to an outlet end of the external straw;
a discharge chamber within the cap body being in fluid communication with the internal passageway of the external straw;
a metering valve configured to allow a flow of beverage from the beverage container to the discharge chamber when the metering valve is open and to substantially preclude the flow of beverage into the discharge chamber when the metering valve is closed;
a diaphragm configured to open the metering valve when the diaphragm is activated and to close the metering valve when the diaphragm is deactivated, the diaphragm further configured to activate when a user sucks on the outlet end of the external straw to create suction within the discharge chamber, the discharge chamber being bounded in part by the diaphragm; and
an actuator on the cap body and coupled to the diaphragm, the actuator configured to activate the diaphragm when the user manually engages the actuator.
