A method and apparatus provides a coffee beverage having a reduced terpene content, in which terpene content is reduced by increasing the particle size of the coffee grounds.

A beverage preparation apparatus for automatically dispensing hot beverages, in particular coffee beverages, having a hot water preparation unit which supplies hot water to a brewing apparatus, a water pump for conveying pressurized water in the direction of the brewing apparatus, an outlet device connected to the brewing apparatus via a hot beverage line and a controller which controls automatic preparation and dispensing of the selected beverage after beverage selection. The controller varies the brewing pressure at which the hot water is supplied to the brewing apparatus or the throughflow rate at which the hot water is conveyed, over the preparation operation of the selected beverage in accordance with a predetermined or predeterminable profile. The beverage preparation apparatus has a mechanical operating element having an electrical consumer connected to the controller and via which the profile can be predetermined by a user during a beverage preparation operation.

The present application relates to Dynamic Flow Control in beverage preparation machines, to dynamically regulate the flow rate of water supplied to brewing assemblies of professional espresso coffee machine so as to dynamically modify the coffee dispensing conditions, varying the organoleptic properties of the in-cup beverage accordingly.

A group head (20) for an espresso machine (10), the group head (20) comprising: a group head bracket (36) for detachable engagement with a portafilter (30) holding a puck (22) of ground coffee in a filter basket (64) to dispense an espresso coffee;
a conduit (34) for receiving a flow of water to the portafilter (30); and,
a heater (32) mounted in the group head (20) to heat the flow of water to the portafilter (30).

A device and method for distributing and tamping a ground, beverage making substance, particularly coffee, held in a compartment, as part of a process for making a beverage by passing liquid under pressure through the ground beverage-making substance. The device includes a distributor for evenly distributing the ground substance in the compartment by rotation of the distributor; a tamper for tamping the ground beverage making substance by moving the tamper in a tamping direction, and applying pressure on the ground substance; and at least one driving means. The tamper and distributor are directly or indirectly attached to one another and are concentrically arranged and are configured to be brought into contact with the ground substance from the same direction.

A beverage extraction device includes a mesh member, a cover member that is movable between a first position and a second position; a scraper portion, an upper end portion of which is pivotally supported by the cover member with a lower end portion of the scraper portion being swingable along a vertical direction, that takes a basic attitude in which the lower end portion is positioned lower than the upper end portion under a normal condition, the lower end portion being configured to slide on the mesh member when the cover member is moved from the first position toward the second position; and a contact member configured to come into contact with the scraper portion sliding on the mesh member to cause the scraper portion to take an attitude in which the lower end portion swings upward when the cover member approaches the second position.

A system for creating infused beverages that includes a solvent flow management system having a pump housed in a pump body and operably coupled to a pump drive system operably configured to drive the pump to induce a flow of solvent, housed by the pump, through a solute housed in a brewing chamber to generate an infused solution. The system also includes a heating element disposed within the pump body, outside of fluid contact with the solvent, and is operably configured to activate and thermally couple with the solvent housed by the pump through conduction within a material of the pump body. An electronic control system is also provided that is operably configured to activate the pump drive system and to activate the heating element.

A coffee percolator (1) includes: a delivery unit (2) configured to deliver water to a filter cup (7) for producing a coffee infusion; a pump unit (3) in fluid connection with said delivery unit (2), and configured to draw water from an external water supply, and to feed said water in a controlled way to said delivery unit (2); a dispensing unit (4) arranged between said delivery unit (2) and said pump unit (3), and configured to take a volumetric amount (Q) of said delivered water; a regulator unit (5) arranged between said delivery unit (2) and said pump unit (3), and configured to control the pressure of the delivered water; an electronic control unit (6) operatively connected to said regulator unit (5), and configured to control, through said regulator unit (5), the delivery pressure (p) of the delivered water; wherein said control unit (6) is operatively connected also to said dispensing unit (4), and configured to define, while delivering said water from said delivery unit (2), two subsequent regulation stages, wherein said delivery pressure (p) is regulated according to one or more predetermined delivery times (t) and one or more volumetric amounts (Q), respectively.

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.

An espresso extraction device and an espresso extraction method are described that utilize a control unit that controls an operation of a valve unit or a pressure unit that adjusts pressure applied to an extraction unit of the device based on sensing data of a sensor unit in the extraction unit. A portafilter can be mounted on a head of the extraction unit, removing bubbles in the pressure unit by filling the pressure unit with a fluid and controlling the operation of the valve unit, removing bubbles in the extraction unit by filling the extraction unit with a fluid and controlling the operation of the valve unit, extracting espresso by exerting pressure to a fluid contained in the extraction unit by operating the pressure unit, receiving extraction pressure in the extraction unit via a sensor unit, and controlling the operation of the pressure unit on the basis of extraction pressure.
