Assemblies, machines, systems, and methods for the generation of superheated are discussed A steam super-heat assembly is employed for generating superheated steam for the preparation of coffee-based beverages. The assembly includes a body that includes an internal cavity, a heating element that includes heating surfaces positioned within the internal cavity, and a flow path within the internal cavity. The body also includes an input that enables fluid access into the internal cavity and an output that enables fluid egress out of the internal cavity. The heating element heats the heating surfaces of the heating element. The flow path enables fluid to flow from the input, through the internal cavity of the body, and to the output of the body. The heating surfaces form a portion of the flow path. When the fluid flows through the internal cavity, the fluid is in direct physical contact with the heating surfaces.

A beverage brewing device includes a lower container for receiving and heating water, a connected upper container for receiving beverage, and a piston-cylinder assembly for receiving grounds, captured within the lower container. The piston-cylinder assembly includes a cylinder, a piston movable in the cylinder, a conical diffuser fixedly attached to the piston, and a freely movable mass disposed between the piston and the conical diffuser. The piston and the conical diffuser define an expansion chamber therebetween. The chamber is formed between a diffuser plate forming the top of the piston and an inner conical surface of the diffuser, which defines an orifice functioning as a nozzle. The diffuser plate has a plurality of holes, on which the grounds are placed. The mass is seated at a valve seat at the entrance of the expansion chamber to operatively block the flow of fluid through the nozzle when the pressure of the fluid is insufficient to displace the weight of the mass. When water is heated in the lower container becomes pressurized sufficiently to pass through the nozzle and displace the seated mass from the valve seat, the water passes through the nozzle at relatively high pressure and velocity, and enters the expansion chamber at lowered pressure. It then flows through the diffuser plate, through the grounds, and into the upper chamber.

In described embodiments, a hot liquid extraction system includes a vessel, a controllable steam and water source external from the vessel which heats the liquid of the corresponding vessel, a filter assembly disposed within the vessel operable to filter and remove a solid from the brewed beverage, and a valve to dispense the filtered beverage from the base of the brew vessel. Some embodiments include one or more valves operable to regulate water flow and steam into the brewing vessel, and a filter operable to separate a brewed liquid from a flavor base and to remove a spent flavor base from the system. Some embodiments include processor control of the system, allowing for operation tailored to individual user requirements that might be downloaded to the processor through various wired and non-wired interfaces.
