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 using 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.

A method of brewing coffee, comprising the steps of providing a coffee brewing device having a porous housing containing a supply of ground coffee with a self-supporting handle dimensioned to be hand-held attached to said housing for positioning and stirring said housing in a liquid to effect brewing of said coffee and further including vent means for venting gases from an interior portion of said housing during brewing, at least partially submerging said housing in a liquid and stirring said housing in said liquid using said handle to produce a flow of aid liquid within said porous housing, and controlling said flow of liquid produced within said housing during stirring to create turbulence therein to agitate said ground coffee while venting gases during said brewing from an interior portion of said housing through said vent means for rapid brewing of said coffee, wherein said step of controlling the flow of liquid to create turbulence therein includes changing the direction of the liquid flow in said housing by providing at least one baffle connected to said housing so as to move with said housing during stirring, said baffle extending within said housing transversely to a direction of said liquid flow produced in said housing during stirring to produce said turbulence therein. A coffee brewing device for rapidly brewing coffee, said device comprising a housing containing a supply of ground coffee, said housing being at least partially submersible in a liquid to effect brewing of said coffee, a self-supporting handle dimensioned to be hand-held attached to said housing for facilitating positioning and stirring of said housing in said liquid, said housing including at least one porous wall which permits liquid to enter said housing when it is at least partially submerged in said liquid, and vent means for venting gases from an interior portion of said housing during brewing, wherein said housing includes means for controlling liquid flow produced within the housing during stirring of said housing in said liquid to create turbulenece therein to agitate said ground coffee while said gases are being vented from an interior portion of said housing by said vent means for rapid brewing of said coffee, and wherein said turbulence creating means includes at least one baffle which is connected to said housing so as to move with said housing during stirring of said housing in said liquid, said baffle extending within said housing transversely to a direction of liquid flow produced in said housing during said stirring for changing the direction of said liquid flow to produce said turbulence therein.
