This invention relates to a nozzle for dispensing and aerating liquids. The nozzle provides for the formation of a substantially hollow conical vortex which aspirates air into the nozzle. The vortex is formed within a first chamber so that the base of the vortex impinges upon the chamber walls. This impingement results in the formation of a turbulent film which, when brought in contact with the aspirated air, results in aeration of the liquid forming the film. A foam-like characteristic is given the liquid by the entrapment of the air as the liquid is dispensed. The aspirated air enters through the downstream end of the nozzle but is directed both towards the front of the vortex and towards the rear of the vortex.
