A flash boiler (10) for a pour over water displacement drip coffee brewing machine, which flash boiler (10) is adapted to deliver hot water to a spray head of the brewing machine. The flash boiler (10) comprises a housing (11), a heating coil (not shown) within the housing (11), an upper cold water inlet (12) connectable to a water holding tank in the coffee brewing machine, and a hot water outlet (13), both inlets (12,13) being located at the upper end (14) of the housing (11) as it is orientated, in use, such that a quantity of cold water mixes with the hot water exiting the housing (11), which quantity of water is sufficient to maintain the temperature of the water at the spray head at 96 degrees C +1- 1.0 degrees C. Water above 96 degrees C is generally accepted in the coffee brewing industry as being detrimental to the quality of the coffee output so there is an advantage to maintaining the temperature of the water at the spray head to close to the industry desired temperature of 96 degrees C. |
