Abstract
A siphon coffee maker consists of a lower container into which water is poured and which is heated with an electric heater, an upper container for containing coffee powder, the upper container communicating with the lower container so that hot water is transferred between the containers through a water feed tube due to siphon effects, and a pressure reducing valve which communicates the lower container with the atmosphere. The pressure reducing valve is opened for approximately 60 seconds for a soak-like processing when the temperature of the water reaches approximately 100.degree. C. Alternately, a pressure reducing valve is kept opened from the time when the temperature of the lower container reaches approximately 105.degree. C. to the time when the ingredients extracting operation is completed.
