Method and apparatus for controlling brewed beverage quality

A brewing system comprising:

• a source of brewable product;
• a source of heated water;
• a brewing chamber that receives brewable product from the source of brewable product, and receives heated water from the source of heated water, wherein the brewing chamber is configured to dispense a brewed liquid produced from the received brewable product and heated water 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 is dispensed, wherein the sensor generates time-dependent data corresponding to the measured property, and communicates the time-dependent data to the controller.
