An automatic machine for making coffee or a similar beverage includes an infusion chamber at atmospheric pressure and adapted to accommodate a mixture of liquid such as hot water and a material serving as the base of the beverage. The infusion chamber has at the bottom thereof a surface permeable to fluids and impermeable to the material. An extraction chamber is positioned below the bottom of the infusion chamber and communicates therewith through the surface. A first control mechanism is positioned within the extraction chamber for moving upwardly therein to force air through the surface into the mixture in the infusion chamber and for moving downwardly within the extraction chamber to extract beverage from the infusion chamber through the surface into the extraction chamber. A second control mechanism is provided within the extraction chamber for forcing beverage within the extraction chamber therefrom under pressure to a dispensing area.
