A sprayhead (10) for a pour over coffee brewing machine for delivering hot water to coffee grounds held in a brew basket therebelow, has a housing (11) with a water inlet (12) at one end thereof, which is connectable to an intermittent source of hot water. A plurality of spaced apart hot water outlets (14) are arranged at the other end (15) of the housing (11). A holding chamber (16) for accumulating a quantity of hot water therein is located within the housing (11) and is connected to the water inlet (12). A dispensing chamber (18) is located within the housing (11) and below the holding chamber (16), in use. A bell siphon (20) located in the holding chamber (16) delivers the accumulated quantity of water from the holding chamber (16) to the dispensing chamber (18), and thence to the coffee grounds, once the water level in the holding chamber (16) rises above an open end (24) of a siphon tube (21). The delivery of the accumulated water by means of the bell siphon 20 converts an intermittent supply of water into a smoother dispensing of hot water from the sprayhead (10). |
