A steam outlet tube assembly for preparing beverages includes a steam tube having a terminal length portion including an outlet end. The outlet end of the first conduit is located at the terminal length portion of the steam tube. There is further provided a second conduit having an outlet end communicating with the steam tube at the terminal length portion thereof; and a mechanism for selectively placing the second conduit into an unblocked position and into a blocked position. In the unblocked position the steam passing through the steam tube draws liquid through the first conduit and draws air through the second conduit to effect a discharge of a steam/liquid/air mixture through the outlet end of the steam tube. In the blocked position the steam passing through the steam tube draws liquid through the first conduit, to effect a discharge of solely a steam/liquid mixture through the outlet end of the steam tube.
