Abstract
A coffee maker with continuously adjustable water flow rate, continuously adjustable feedback-controlled water temperature, and low thermal mass allows baristas to experiment with and digitally program and/or record different flow-rate and temperature profiles (brewing profiles) over the course of brewing a cup or batch of coffee. Brewing profiles may be recorded on one machine and reproduced (played back) on another machine, allowing reproducibility of subtle flavor variations in brewed coffee.
Claims7
A beverage brewer comprising:
- heating means for heating water;
- an output spout where water having passed through said valve means and having been heated by said heating means exits said brewer;
- temperature sensing means capable of sensing at said spout the temperature of water flowing out of said spout, and producing a sensed temperature signal;
- a manually-directable output spout operable to manually direct water output flow to different locations on a basket of coffee grounds;
- and
- water flow rate control means mounted on said output spout.

A beverage brewer comprising:
- heating means for heating water;
- valve means for controlling the flow of water through said beverage brewer;
- an output spout where water having passed through said valve means and having been heated by said heating means exits said brewer;
- temperature sensing means capable of sensing the temperature of water flowing out of said spout, and producing a sensed temperature signal;
- temperature controller means connected to said temperature sensing means, and capable of controlling the amount of heat put out by said heating means, in response to the sensed temperature signal;
- temperature adjustment means allowing an operator to adjust the temperature of water flowing out of said spout dynamically as said water is flowing;
- and
- water flow rate control means mounted on said output spout.
