Abstract: A beverage container is provided for separately storing a liquid apart form an additive until mixing. The beverage container has a vessel for retaining the liquid and a compartment for retaining the additive. The vessel has an open base at an end and a release valve is connected to another end. A base coupler is connected to the open base. The compartment has a connector at each of an open end and an opposing closed end of the compartment. Connecting the closed end and the open end of the compartment to the base coupler selectively separates and mixes the liquid and the additive, respectively. The beverage container has a closure for sealing the open end of the compartment when the liquid and additive are separated. A method for separating storing and mixing a liquid and additive is also provided. A kit assembly for a beverage container is also provided.
