Claim:
A brewing system comprising: a hopper configured to dispense brewable product; a reservoir configured to dispense heated water; a brewing chamber that receives brewable product from the hopper, and receives heated water from the reservoir, wherein the brewing chamber is configured to produce a brewed liquid from the received brewable product and heated water and to dispense the brewed liquid in a fluid stream; a controller that controls the operation of the brewing system, the controller comprising a processor, an input signal port, an output signal port, and a memory module; a sensor positioned to intercept the fluid stream, and operable to measure a property of the brewed liquid at a fixed location as the brewed liquid flows by the sensor, wherein the sensor generates time-dependent data corresponding to the measured property, and communicates the time-dependent data to the controller; wherein the controller uses the time-dependent data to control the amount of brewable product received by the brewing chamber.
