The stopper has a tubular duct (2, 5, 6, 9, 10, 11, 16, 17) adapted to put the residual volume of air present inside the bottle in communication with the outer ambient through a membrane (3) arranged transversely to said tubular duct and allowing passage of oxygen from bottle inside to the outer ambient and vice versa.
