Abstract
A free-standing coffee-maker assembly including a brewing basket that is seated on a decanter, a paper filter having a flat base being nested within the basket. Boiling water from a reservoir seated on the basket is sprayed over a bed of ground coffee lying over the flat base of the filter, the water percolating through the bed to produce a coffee extract which is discharged through a central opening in the bottom of the basket into the decanter. The bottom of the basket is provided with a depressed region surrounding the central opening to define a well and an annular inactive zone concentric therewith. The well is provided with upstanding ribs to maintain a space between the base of the filter and the well, whereby the coffee extract is free to flow through the filter base only in the region thereof overlying the well. This restriction in the filtering action renders the assembly effective throughout a broad operating range so that the same assembly and same sized filter may be used to brew a large amount of beverage or a much smaller amount.
