    Abstract: A coffee maker comprising a main or external tank for containing water and steam under pressure, a secondary or internal tank in the main tank for containing water under pressure to be used in making espresso, and a heating element in the main tank adjacent to the secondary tank for heating the water in the main tank and maintaining the water in the secondary tank at a substantially constant temperature. An aromatic coffee water supply is also maintained in a separate tank to feed a shower arrangement for making aromatic coffee.
