A cappuccino attachment for an espresso machine, the attachment comprising, in combination:

• an upper frother body having an internally threaded upper opening, an externally threaded lower opening, and an aperture formed adjacent the upper opening;
• a cylindrical extension having a first end integral with the frother body intermediate its upper and lower openings, and a second end opposite the first end, a first aperture formed within the second end, a second aperture formed through the cylindrical extension intermediate the first and second ends of the cylindrical extension;
• an internal passage providing a fluid interconnection between the upper opening of the frother body, the lower opening of the upper frother body, the first aperture of the cylindrical extension, and the second aperture of the cylindrical extension, the passage being internally threaded adjacent the lower opening of the upper frother body;
• an air intake adjustment mechanism having a cylindrical member with a hollow interior, the cylindrical member having a diameter less than the diameter of the cylindrical extension, the cylindrical member having a first end connected with the second end of the cylindrical extension, the air intake adjustment mechanism including a conical air adjustment screw operatively engaged with the hollow interior of the cylindrical member, the screw functioning to control the amount of air passing into the internal passage;
• a hollow frothing tunnel having an externally threaded upper opening adapted to be connected with the internal threads of the passage adjacent the lower opening of the upper frother body, the hollow frothing tunnel having a plurality of apertures formed within its surface, the frothing tunnel functioning to aerate passing fluids;
• a lower frother body having an internally threaded upper opening, and a lower aperture, the internally threaded upper opening of the lower frother body adapted to be connected to the externally threaded lower opening of the upper frother body;
• a steam valve attachment assembly, the assembly including a locking screw positioned through the aperture of the upper frother body, and an O-ring seal positioned about the internal passage below the locking screw, the attachment assembly adapted to engage a steam valve assembly.
