ABSTRACT:
An espresso machine has a coffee brewing chamber, a water reservoir and a water heater. Two electrical pumps 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 at the outside of the machine allows a user to select which one of the pumps he wishes to energize.
