Coffee makers with features for rapid and/or multiple extraction processes, and associated systems and methods, are disclosed. A representative method for brewing coffee includes placing ground coffee on a filter element of a brew chamber, directing heated water into the brew chamber and in contact with the ground coffee and, during a first phase, brewing coffee in the brew chamber without subjecting the coffee to a pressure differential of at least 150 torr between the brew chamber and a coffee chamber to which the brew chamber is coupled, the coffee chamber having a capacity of 200 mL or more. The representative method further includes, during a second phase, extracting the coffee from the brew chamber through the filter element and into the coffee chamber via a pressure differential of at least 150 torr between the brew chamber and the coffee chamber.

An upward flow extraction method, apparatus, and extract are disclosed. The upward flow extraction method can comprise loading extraction material into an extraction cell having a bottom portion and a top portion; introducing a first aliquot of extraction medium through the bottom portion of the extraction cell; expelling gas from the extraction cell through the top portion of the extraction cell; closing the top portion of the extraction cell and increasing the pressure in the extraction cell as extraction medium flows into the bottom portion of the extraction cell; stopping the flow of extraction medium into the extraction cell; steeping the extraction material in the extraction medium under pressure to produce an extract; and introducing a second aliquot of extraction medium through the bottom portion of the extraction cell to push extract through top portion of the extraction cell.

A first coffee brewing and dispensing system that includes a removable grounds chamber assembly that includes a basin for holding ground coffee, an extendable dispensing spout, and a valve mechanism for opening and closing the dispensing spout; a brewing chamber assembly positioned on top of the removable grounds chamber assembly; and a lid/plunger assembly adapted to be inserted into the brewing chamber and removable grounds chamber, wherein the lid/plunger assembly includes a press rod, a handle mounted on the press rod, wherein the handle includes a trigger mounted therein, a lid mounted on the press rod below the handle, a wiper assembly mounted on the press rod below the lid; and a filter assembly mounted on the press rod below the wiper assembly, wherein the wiper assembly may be moved independently of the filter assembly by actuating the trigger in the handle.

A filter for a coffee machine comprises a cup-shaped body (2) for containing coffee powder, having at least a bottom wall (3) having an opening (5); a filtering wall (6) placed in the cup-shaped body (2) upstream of the opening (5) and removably associated with the cup-shaped body (2); a seal (7) placed at least between one edge (6b) of the filtering wall (6) and the cup-shaped body (2); a tightening member (8) active on the filtering wall (6) and on the seal (7) so as to reversibly fix said filtering wall (6) and said seal (7) to the cup-shaped body (2); said tightening member (8) comprising a tubular element (9) connected to the filtering wall (6) and to the seal (7) and arranged through the opening (5); said tubular element (9) being directly constrained to the cup-shaped body (2) by means of a bayonet-type connection.

A dispensing group for an espresso coffee machine is described. The group comprises: a coffee boiler configured to contain pressurized hot water; a supply duct for feeding hot water under pressure towards a puck of coffee powder; and a filter-holder support comprising guides (30) which form at least one sliding surface for slidably supporting a filter holder, wherein said filter-holder support is rotatable between a first position for inserting the filter holder and a second dispensing position and wherein said dispensing group comprises a mechanical locking device for locking the filter-holder support in the second dispensing position.

Coffee makers with features for rapid and/or multiple extraction processes, and associated systems and methods, are shown. A representative method for brewing coffee includes placing ground coffee on a filter element of a brew chamber, directing heated water into the brew chamber and in contact with the ground coffee and, during a first phase, brewing coffee in the brew chamber without subjecting the coffee to a pressure differential of at least 150 torr between the brew chamber and a coffee chamber to which the brew chamber is coupled, the coffee chamber having a capacity of 200 mL or more. The representative method further includes, during a second phase, extracting the coffee from the brew chamber through the filter element and into the coffee chamber via a pressure differential of at least 150 torr between the brew chamber and the coffee chamber.

A coffee bean grinder 1 has a hopper 2 into which coffee beans are inserted. The grinding unit 3 grinds coffee beans supplied from the hopper 2. The discharge unit 4 discharges coffee beans ground by the grinding unit 3. The mounting unit 5 mounts a portafilter 6 to be closely pressed against the bottom end of the discharge unit 4. The discharge unit 4 has a guide path 41 facing vertically downward, and a tapered section 42 in which the inner diameter increases towards the bottom. A sloped section 502 of a close-fitting member 50b, attached to the bottom end portion of the tapered section 42, is closely pressed against a top surface 63a of the filter basket 63 of the portafilter 6. The tapered section 42 has a hole 44 for allowing air in the airtight space to escape, thereby allowing the coffee beans to fall.

Apparatus for measuring the operating parameters of espresso coffee machines, comprising: a filter-holder body configured to be associated with a water dispensing nozzle of an espresso coffee machine; said body internally defining a chamber for the passage of the water dispensed by said nozzle; a filling element arranged in said chamber and having a cavity for the passage of the water dispensed by the nozzle towards an outlet duct; a water outlet terminal element associated with said filter-holder body downstream of said chamber and defining said water outlet duct; and reading means for the water pressure and temperature values passing from the chamber to the outlet duct; said reading means comprise at least one pressure reading device operatively engaged with said water outlet terminal element and at least one temperature reading device operatively engaged at said cavity obtained in the filling element.

A coffee puck removal device (10) to remove a coffee puck (24) from a portafilter (20) is disclosed herein. The coffee puck removal device (10) has an open compartment (22) containing the coffee puck (24), the coffee puck (24) having an exposed major outer face (26) and a major inner face (28) when the coffee puck (24) is located in the open compartment (22). The device (10) includes: a body (12) having a rim (14) surrounding an aperture (16), with the rim (14) being configured to engage the portafilter (20), with the open compartment (22) facing the body (12) to inhibit air passing between the portafilter (20) and the rim (14); and a vacuum source (30) to remove air from the aperture (16) so that air pressure applied to the major inner face (28) is greater than air pressure applied to the exposed major outer face (26) so that the coffee puck (24) is removed from the portafilter (20).
