A method and system for liquid dispensing provides an additive to a base liquid in a container. The additive may be enclosed by an additive bladder that is contained in a container cap and supported by a retaining element having an additive dispensing hole. When the cap is screwed down, a convex element in the cap may press the additive bladder and dispense the additive. The cap may then be removed and may be configured to internally retain the retaining element and the emptied additive bladder. In certain instances, the additive bladder may be omitted from the method and system.
