ABSTRACT:
According to the present invention, water is placed in a water reservoir constructed of plastic microwave-transparent, pressure-resistant material. A funnel positioned on the upper surface of filter compartment is supported on the upper edges of the water reservoir with the spout extending downwardly into the water reservoir. A lower filter is placed into the filter compartment, and coffee grounds or other espresso particulate substance is placed on upper surface of the lower filter. An upper filter is then positioned on the upper surface of filter compartment to restrain the coffee grounds or other particular substance during brewing. A filtrate reservoir is placed over the funnel, and twisted, thereby engaging threads to join the water reservoir and the filtrate reservoir. A filtrate splash cover is attached to the upper edges of the filtrate reservoir. The assembled espresso device is placed into a microwave oven. As water in the water reservoir begins to boil, steam is generated, and boiling water is displaced upwards through the funnel and grounds, forming espresso. The filtrate splash cover provides for both venting and fluid retention during brewing. A resilient gasket, in conjunction with a plurality of vent passages, provides an additional means for pressure relief. The espresso is automatically emptied into the filtrate reservoir, which is designed to function as a drinking cup for individually-sized portions.
