Aspects of the present disclosure relate to the brewing of beverages from a liquid, such as water, and a flavor base, such as tea, cocoa, or coffee. Specifically, aspects of the present disclosure enable the brewing of beverages at a rapid rate by enabling removal of spent flavor base (e.g., coffee grounds) from a brewing chamber. In one embodiment, a filter is provided in fixed attachment with a wiper. After a brewed beverage is forced from the brewing chamber through the filter, the filter can be removed from the brew chamber. Removal of the filter causes the wiper to pass over the brew chamber, sweeping away spent flavor base and preparing the brew chamber for subsequent use. In some embodiments, a scraper may be positioned such that removal of the filter from the brew chamber causes the scraper to remove spent flavor base from the filter and/or wiper.

Beverage brewer with flavor base removal

Aspects of the present disclosure relate to the brewing of beverages from a liquid, such as water, and a flavor base, such as tea, cocoa, or coffee. Specifically, aspects of the present disclosure enable the brewing of beverages with a level of precision that can yield a uniform taste from cup to cup, and at a rapid rate. In one embodiment, a liquid is heated in a reservoir to a predetermined temperature. Prior to brewing a beverage with the liquid, the liquid may be passed through a temperature control unit to cool the liquid to a desired brewing temperature. By utilizing such a temperature control unit, the brewing temperature can be varied on a per-beverage basis. Moreover, utilization of a temperature control unit can enable the liquid to be brought to a desired brewing temperature relatively rapidly.

Temperature-controlled beverage brewing

A machine for brewing a beverage such as coffee includes a chamber and a piston disposed in the chamber. The piston is operable to move to a first position to allow the chamber to receive a liquid and a flavor base such as ground coffee, to remain in the first position for a time sufficient for the beverage to brew, and to move to a second position to dispense the beverage by forcing the beverage out of the chamber. By modifying some or all steps of the French press brewing technique, the machine can typically control coffee-brewing parameters with a level of precision that yields brewed coffee having a uniform taste from cup to cup, and can typically brew the coffee with a speed that renders the machine suitable for use by establishments that serve significant amounts of coffee.
