Abstract: A beverage bottle includes a primary compartment to store an existing fluid therein, a pod in communication with the primary compartment, a cap in communication with the pod. Such a cap includes a nozzle in communication with the primary compartment. A primary travel path extends from the primary compartment to the nozzle. Upon receiving a first user input at the primary compartment, the fluid is caused to discharge upstream along the primary travel path while remaining isolated from an interior of the secondary compartments. The pod includes a plurality of secondary compartments adapted to store a plurality of existing additives therein, respectively. A plurality of secondary travel paths extend from the secondary compartments into the primary compartment. In this manner, upon receiving a second user input at the pod, the existing additives are caused to selectively discharge downstream along the secondary travel paths, respectively.
