A bottle cap assembly (20) includes a stopper (22) and an over-cap (24) removably coupled to a bottle (12). The stopper (22) includes a cork (30) fitted to a stopper cap (32) with a snap-in retention ring (34) so as to avoid the need to use any glue. The over-cap (24) includes downwardly extending prongs (75), each having medial tab (77) that releasably locks the over-cap to the stopper cap and bottle. The prongs releasably catch a ledge (64) defined by the stopper. An inner sleeve of the over-cap conforms to an outer surface (16) of a top portion (14) of the bottle (12).
