Abstract: A porous bag for brewing a brewable substance held therein, includes an enclosure bag including walls made from a porous material, with the brewable substance held in the enclosure bag; and an accessible opening in one wall of the enclosure bag for receiving a liquid supply tube therein for supplying liquid to the enclosure bag, the accessible opening preventing the brewable substance from escaping so that the porous bag can be used as a steeping bag in a liquid, while also permitting access to the opening to permit supply of the liquid therein from the liquid supply tube inserted therethrough.

Abstract: A brewable beverage making machine includes a brewing chamber assembly for holding a brewable substance therein, the brewing chamber assembly including inlet openings for supply of an input liquid therein, an outlet opening at an upper end thereof, and a discharge opening for discharging the brewed liquid, the inlet openings being sized and oriented to cause turbulent agitation; a heater which heats the input liquid supplied to the brewing chamber assembly; an pump for supplying heated liquid from the heater through the inlet openings; a first valve connected with the outlet opening; and a microprocessor which opens the first valve during initial filling of the brewing chamber assembly with the heated liquid and closes the first valve when the heated liquid reaches a predetermined level in the brewing chamber assembly to cause pressurization of the heated liquid in the brewing chamber assembly during a brewing operation.
