An automatic stopper for serving drinks, characterized in that it consists essentially of a small container of spherical shape, which is attached by means of a nozzle to a cork, intended to hold the stopper to the desired bottle, this cork being crossed by two tubes, one of them of greater length than the other, which is provided in its lower extremity with a small hole, destined to put in communication the interior air of the bottle with the outside, and whose upper extremity, open, ends in the air chamber located in the center of said spherical container, thus establishing the air pressure necessary for the liquid to circulate freely.
