Abstract: A beverage bottle nipple adapter and funnel apparatus includes a perimeter wall that has a first edge and a second edge positioned opposite of each other. A peripheral lip is attached to and is coextensive with the first edge. The peripheral lip extends away from the perimeter wall. The peripheral lip has an exterior surface and an interior surface each being threaded. The interior surface has a size configured for receiving and threadably coupling to the threaded neck. The perimeter wall may be positioned in funnel position extending upwardly from the threaded neck or in a nipple receiving position extending downwardly from the threaded neck. A nipple is positioned in a threaded nipple coupler and the threaded nipple coupler is threadably coupled to the exterior surface of the peripheral lip when the perimeter wall is in the nipple receiving position.
