Estimating the term…
Embodiments are directed towards regulating flow rate in an espresso machine, during a multi-phase brewing process which includes a pre-brew and an extraction phase. During the pre-brew phase, coffee grounds are slowly pre-wetted and/or out-gassed with a first volume of water delivered at a first flow rate. During the extraction phase, a second volume of water is delivered, at a second flow rate, to extract espresso, where the second volume is delivered at a generally greater pressure than the first volume. The second flow rate is greater than the first flow rate. The flow rates, volumes, and pressures are regulated by the espresso machine, which includes a flow rate regulation assembly that comprises first and second flow paths and first and second valves. Baristas may vary the flow rate, volume, and pressure of water throughout the brewing process by opening, closing, or otherwise adjusting at least one of the valves.
A brew flow rate regulation assembly for regulating a brew flow rate of pressurized water within an espresso machine while brewing a coffee beverage using the pressurized water, comprising:
A method for producing a brewed coffee beverage using an espresso machine, the method comprising:
