The bottle stopper includes a plug and a cylindrical stopper member slidably mounted to an elongated rod. The stopper member has a tapering cavity and the plug has a tapering shaped and size complementary to the cavity of the stopper member. The plug may be pushed to a lowermost position to mate with the cavity of the stopper member for causing the stopper member to be in an expanded mode for sealing the bottle. The plug may be pulled upwards outside of the cavity of the stopper member to change the stopper member into a contracted mode such that it may be extracted by merely lifting the plug further upwards. The stopper may be re-used repeatedly.
