ABSTRACT OF THE DISCLOSURE An improved method of brewing coffee and a device therefor are disclosed. The method involves the steps of providing a coffee brewing device having a porous housing containing a supply of ground coffee and having a self-supporting handle dimensioned to be hand-held attached thereto for positioning and stirring the housing in a liquid, the housing also including a vent for venting gases from an interior portion of the housing, the gases being generated during brewing, at least partially submerging the housing in the liquid and stirring the housing in the liquid sin the handle to produce a flow of liquid in the housing, and controlling the flow of liquid produced within the housing to create turbulence therein to agitate the ground coffee while the generated gases are being vented from the housing by the vent for rapid brewing of the coffee. The turbulence is created by changing the direction of the flow within the housing using baffles positioned inside or on a side of the housing and/or by providing a flexible porous side wall of the housing which can flutter during stirring, that is, can move a substantial distance inwardly and outwardly with respect to the adjacent housing during stirring to create turbulence in the liquid flow within the housing to agitate the ground coffee. Another manner of creating turbulence includes the provision of irregular surfaces on the housing sidewall and/or baffle to disrupt laminar flow thereby creating a turbulent state.
