Abstract
A machine for brewing hot beverages, such as coffee, has a container for a supply of fresh liquid with two communicating sections one of which communicates with the atmosphere and the other of which has a bottom wall directly above an electric heater. Two or more siphons are used to convey streams of boiling liquid from the other section into a holder for a supply of flavoring agent. The siphons, the holder and at least the second section of the container are made of a non-metallic material (particularly porcelain, certain plastics, glass, ceramic or earthenware) which does not adversely affect the aroma of the beverage.
