A percolator, wherein a container, containing a measure of ground coffee, is inserted inside a fixed cup, which has a vertical first axis, is positioned with its concavity facing upwards, and has a lid which rotates, about a second axis crosswise to the first axis, to and from a closed position closing the cup; the lid having a pressurized-hot-water sprinkler which, when the lid is in the closed position, is moved, by a piston carried by the lid, onto the cup to define, with the cup, a percolating chamber for housing the wafer and a bolt device to lock the lid in the closed position.
