Abstract: A bottle cap assembly includes a stopper and an over-cap removably coupled to a bottle. The stopper includes a cork fitted to a stopper cap with a snap-in retention ring so as to avoid the need to use any glue. The over-cap includes downwardly extending prongs, each having medial tab that releasably locks the over-cap to the stopper cap and bottle. The prongs releasably catch a ledge defined by the stopper. An inner sleeve of the over-cap conforms to an outer surface of a top portion of the bottle.
