A water bottle system for adding an additive, which may be flavoring, to the line of flow without contaminating the main reservoir. The system may include a water bottle with a lid feature that may maintain a flavor that may be infused into the water within the water bottle. The infusion of the additive may be adjusted by a user to have the desired concentration of additive to a user's liking. The additive cartridge may be reusable or disposable depending on a user's preference.
