ABSTRACT:
An apparatus for automatically brewing coffee, tea, or the like comprises a cell for automatically drawing a predetermined amount of water from a water reservoir. A heating unit heats the water in the cell up to boiling and subsequently generates pressurized steam in the cell. The heated water in the cell is forced out of the outlet, which is positioned at the lowest portion of the cell, and delivered under the pressure of the pressurized steam to and through the coffee grounds, tea, or the like in a container. The pressurized steam is released into atmosphere by a valve means before it reaches the coffee grounds, tea, or the like in the container in one embodiment of the present invention and it passes through and drys the wet coffee grounds, tea, or the like in the container in the other embodiment.
