<p>The present invention relates to a coffee-brew percolator. The percolator comprises an outer vessel, a bottomless boiler slidably and removably arranged in the vessel, and one or more filters designed to confine in the vessel a space above the boiler for accommodating coffee powder. The boiler has one or more calibrated openings or holes through which steam or vapor can be discharged in use. The boiler is free to slightly move towards and away from the space containing coffee powder so that the latter is packed and amounts of water calibrated in accordance with the pressure level in the boiler are released from the bottom of the boiler towards the coffee powder in the space.</p> |
