A device for brewing a beverage such as coffee, tea, espresso, latte or mocha comprising: a supply of flavor-containing materials adapted to be extracted by a hot liquid; a container having a bottom, a side wall, a top opening, and a containing chamber between said top opening and said bottom; a filter for dividing said containing chamber into an extraction chamber for enclosing said flavor-containing materials and an exchange chamber, said filter comprising a first surface adapted to contact said flavor-containing materials, a plurality of filtration openings adapted to allow liquid extraction to pass through while block all or substantially all solids and a second surface for receiving the beverage from said filtration openings; wherein said exchange chamber comprises said second surface of said filter and at least part of the side wail of said container, said exchange chamber being adapted to receive a depth of liquid above said second surface of said filter; wherein said filter is connected to said container in such a way that said container can be moved according to a transfer-causing motion comprising at least one of swirling, vibrating and shaking motions to cause the flavors to transfer from said extraction chamber to the depth of liquid in said exchange chamber, thereby quickly converting the depth of liquid to a reservoir of beverage ready for drinking from said exchange chamber; and wherein said extraction chamber comprises said first surface of said filter and a film to enclose said flavor-containing materials, said film being adapted to be received in said containing chamber and to be impermeable to prevent the liquid extraction in said extraction chamber from entering the space between the side wall of said container and said film, said film being further adapted to be sufficiently flexible to collapse when said container is tilted to produce a liquid head on said first surface of said filter to drive the liquid extraction out of said extraction chamber to said second surface of said filter into said exchange chamber. 58. A device for brewing a beverage such as coffee, espresso, latte or mocha from a supply of flavor-containing materials comprising: a container comprising a bottom, a top opening, a side wall and a containing chamber defined by said side wall and bottom; a filter for dividing said containing chamber into an exchange chamber and extraction chamber, said filter comprising a first surface adapted to contact the supply of flavor-containing materials, a plurality of filtration openings adapted to allow the liquid extraction in said extraction chamber to pass through as a beverage while block all or substantially all solids and a second surface for receiving the beverage from said filtration openings; a connector for connecting said filter to said container in such a way that said container can be moved according to a transfer-causing motion comprising at least one of swirling, vibrating and shaking motions to cause the transfer of flavors from said extraction chamber to exchange chamber; wherein said exchange chamber comprises said second surface of said filter and the side wall of said container to enable a depth of liquid to form therein and said extraction chamber is comprised of a closed chamber comprising at least said first surface of said filter to enclose the supply of flavor-containing materials therein; and wherein at least part of said closed chamber is located in the vicinity of said top opening of said container and at least some of said filtration openings on said closed chamber are adapted to enable the flavors of the flavor-containing materials enclosed by said closed chamber to transfer sufficiently rapidly to the liquid in said exchange chamber by said transfer-causing motion of said container without substantially collapsing or moving said closed chamber relative to said container, thereby converting the liquid in said exchange chamber to a beverage full of flavors ready for drinking in about 5 to 30 seconds.
