ABSTRACT:
An automatic coffee brewer including a water heating tank, a funnel-like holder for ground coffee, a siphon device for dispensing a predetermined amount of hot water from the tank through the grounds holder, and a bypass valve for directing approximately 40% of the hot water around the grounds and directly to an unheated, thermo-insulated beaker so that the resultant brew has extracted about 60% of the soluble solids in the coffee to yield a better tasting brew free of bitterness and astringency. The use of the thermo-insulated beaker enables the brewed coffee to be kept hot without further heating for several hours and avoids bitterness derived by continuous heating.
