A cylindrical container has an open top, and the bottom is formed by a piston reciprocable in the container. A filter is laterally and vertically movable between an initial position to open the top of the container and a subsequent position to close the top of the container. Supply means above the container mixes ground coffee and hot water and includes one or more partitions to cause the mixture to flow vertically downward into the open top of the container with hardly any turbulence so that the ground coffee floats on the hot water. The filter is then moved to close off the top of the container, and the piston is moved upwardly to press the water through a layer of coffee disposed at the underside of the filter and thence through the filter to an outlet.
