The systems and methods provide a container assembly comprising: a container having a known storage capacity for storing a liquid; an additive dispensing assembly, the additive dispensing assembly dispensing variable, non-zero quantities of one or more additives into the liquid stored in the container; one or more vessels that each contain one of the additives, of the one or more additives, to be dispensed into the liquid; and a gas dispensing assembly, the gas dispensing assembly releasing a gas into the liquid stored in the container, and the gas dispensing assembly including: an onboard gas tank; a valve assembly; and a gas outlet, and the valve assembly controlling flow of gas from the onboard gas tank, through the valve assembly, and to the gas outlet so as to output the gas into the liquid; and wherein the valve assembly, to perform the controlling the flow of gas, is movable between: an open position, in which flow of gas is allowed to flow from the onboard gas tank to the gas outlet; and a closed position in which the flow of gas is prevented to flow from the onboard gas tank to the gas outlet.

A beverage apparatus hand-holdable by a user to be portable, can include a beverage chamber housing that includes a chamber for storing a consumable liquid. The beverage apparatus can include a dispensing assembly that includes a receptacle. The receptacle can retain a vessel. The vessel can include an electronic tag and can contain an additive. The dispensing assembly can be operatively controllable by a controller to output the additive from the vessel into the consumable liquid. The beverage apparatus can include one or more sensors, devices, or assemblies that can be used to detect a volume of liquid in the chamber or a liquid level in the chamber. The beverage apparatus can include an apparatus computer processor portion (ACP) and an apparatus database portion.
