An express machine has a coffee brewing chamber, (3a) a water reservoir (11) and a water heater (8) and two electrical pumps (12,13) are provided: one capable of supplying a smaller quantity of water from the reservoir via the heater to the brewing chamber so as to make a regular-strength coffee beverage, and the other capable of supplying a considerably larger quantity of water from the reservoir via the heater to the brewing chamber, so as to make a weaker-strength coffee beverage from an identical quantity of coffee. A selector (22, 23) at the outside of the machine allow a user to select which one of the pumps he wishes to energize (the sole figure is referred to). |
