Abstract: A portable aerator comprising: a main aeration body; a base portion; an internal cavity; at least one ventilation shaft; a spout portion; an aeration opening; and an aeration inlet. The internal cavity comprises a threaded channel and cavity extends from a base portion opening to a spout portion opening. The internal cavity is configured to pass a liquid, such as wine that enters the internal cavity body at the base opening out through the spout portion opening. The threaded channel is threaded on an interior surface, such that the threaded channel is configured to matingly engage and disengage with a worm of a corkscrew bottle opening device, such as a waiter's wine key, via twisting and untwisting, respectively. The aerator device may have at least one ventilation shaft, an aeration shaft, and/or an extension tube.
