A gas source for pressuring sparkling and other beverage containers, e.g., to re-pressurize the container to keep a carbonation level of beverage during storage. A gas cylinder can include a cap with a flange and catch below the flange. The catch can be engaged by a cylinder support to move the cylinder into contact with a piercing element to pierce the gas outlet of the cylinder and form a seal between the cylinder and gas receiver. A pressure indicator can have a single pressure sensor to indicate a capacity of a gas cylinder to deliver pressurized gas and a pressure in a beverage container.

On-the-go carbonation devices and methods are provided, which enable carbonating and enhancing liquid content in various containers, such as drinking bottles, in relation to users' preferences and activity patterns. Devices include a sealed enclosure holding a gas canister, an actuator configured to release gas from the gas canister and break a seal of the sealed enclosure, and a gas passage configured to deliver the released gas, optionally with flavoring and/or supplement additivesinto the liquid. Various configurations of the devices are provided to yield predefined carbonation and mixing of additives by simple actuation. Disclosed methods of carbonation enable configuring the device to be portable and attachable to various types of liquid container. Various types of additives may be used, provided in preparation kits and monitored by an application that supports healthy consumption and enhancements of liquids.

A carbonation machine includes a carbonation head to sealingly couple to a bottle filled with liquid to be carbonated; a piping to introduce and compress carbon dioxide into a space within the bottle above a top surface of the liquid to a predetermined pressure level when the bottle is coupled to the carbonation head; a stirrer to stir the liquid to enhance absorption of carbon dioxide in the liquid when the bottle is coupled to the carbonation head; and a manually operated valve mechanism configured to be moved to any position between a closed position to an open position for user-controlled release of pressure within the space.

A method includes obtaining a cartridge having a first fluid within an interior of the cartridge, where the cartridge includes a valve; obtaining a container having a second fluid within an interior of the container; obtaining a pressurizer; installing the cartridge within the pressurizer; installing the pressurizer within a container opening at a top end of the container; and opening the valve in the cartridge, to flow the first fluid within the interior of the cartridge through a first flow path in the valve, and a second flow path in the pressurizer into the second fluid in the container.

A portable carbonation system and a method for producing a carbonated beverage from a primary liquid through at least one chemical reaction are disclosed. Exemplary implementations may include a base assembly, a beverage chamber, a control interface, and/or other components. The base assembly includes a cavity to hold reactants, a liquid reservoir, a reservoir fill valve, a reservoir drain valve, and/or other components. Operations are triggered by and/or responsive to (mechanical) manipulation of the control interface. The reservoir fill valve controls fluid communication to the liquid reservoir. The reservoir drain valve controls fluid communication from the liquid reservoir to the cavity, which initiates a chemical reaction. Gas generated by the chemical reaction travels to the beverage chamber and produces the carbonated beverage.
