Coffee machine with dynamic flow and temperature control

A method for manufacturing a coffee machine, the method comprising:

• providing an electronic control module, the electronic control module being configured to receive brewing settings, the brewing settings including at least one flow set point and at least one temperature set point;
• providing a portafilter configured to hold coffee;
• providing a group head configured to receive the portafilter;
• providing at least one water line configured to supply water;
• providing at least one syringe pump, the at least one syringe pump being configured to administer predetermined amounts of the water based on predetermined criteria to attain a flow rate according to the at least one flow set point, the flow rate provided by the syringe pump being substantially unaffected by a flow resistance created by the coffee;
• providing an in-line heating element, the in-line heating element being configured to control a temperature of the water to attain the at least one temperature set point during an extraction process;
• and
• providing a feedback loop, the feedback loop being configured to provide the temperature to the electronic control module, the electronic control module being further configured to selectively adjust the temperature based on the brewing settings.
