Abstract

Device and method for brewing coffee comprises a body connected to a container for allowing the formation of a dispersion of flavor-containing materials and liquid and the extraction of the flavor-containing materials to produce a liquid extraction, a porous filter connected to the body and having a first surface for contacting the dispersion, filtration openings for allowing the liquid extraction in the dispersion to pass through but blocking the flavor-containing materials and a second surface for receiving the liquid extraction, and a flow facilitator having a selective opening adapted to allow air to pass through but restrict the flavor-containing materials from passing through. The body and porous filter are adapted to allow the container to be tilted to generate a liquid head to act on the first surface of porous filter to drive the liquid extraction through the porous filter to produce a beverage. A coffee fine removing means may be incorporated into the device to render coffee beverage free of coffee fines to improving coffee smoothness. The device may further comprise an extraction chamber and an exchange chamber for producing a supply of beverage in the container for drinking or dispensing without any need to tilt the container to generate the liquid head.
