Abstract
An expresso coffee maker includes a steam outlet valve for supplying steam to froth milk for making cappuccino coffee. A valve member automatically closes off a tube when a water level in a water compartment falls below a low level. This closing off completes each expresso making cycle and ensures that sufficient water is retained, and sealed off, inside the compartment to sustain a supply of steam for frothing the milk.
