A stopper (1) for closing bottles and more particularly wine bottles is disclosed, at least partially made of synthetic material having at least a generally cylindrical length to be inserted in the bottle neck. 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 an d allowing passage of oxygen from bottle inside to the outer ambient and vice versa. |
