ABSTRACT:
An attachment for combining steam, milk and air which comprises an upper frother body having an upper end defining an inlet and a lower frother body having a lower end defining a discharge outlet. The upper and lower frother bodies are attached to each other so as to establish a fluid passageway between the inlet and the outlet. A frother nozzle is interdisposed in fluid passageway between the inlet and discharge outlet. A manifold attaches to the upper frother body for introducing milk and air into the fluid passageway. A pressure cap, a rigid bushing and a resilient bushing allow releasably attaching of the inlet to a steam supply of an espresso machine. A flush cap releasably attaches to the lower end of the lower frother body to close the discharge outlet so that the steam supply from the espresso machine is directed through the manifold in a reverse flow-like flushing manner whereby the attachment is cleaned without requiring disassembly or disconnection from an espresso machine.
