1. A method of operation of a tankless beverage brewing apparatus, the method comprising: a. providing a tankless beverage brewing apparatus, comprising: i. a controller;ii. a flow path having an inlet at one end connected to a local water supply and one or more outlets at a second end connected to one or more water delivery mechanisms;iii. a spray valve positioned in the flow path;iv. a pressure reducer positioned in the flow path;v. a heater arranged along a portion of the flow path and thermally coupled thereto, wherein when activated, the heater is configured to heat the water to a desired brew temperature, and to maintain the desired brew temperature as the water flows continuously through the flow path;vi. a pressure sensor positioned in the flow path operable to sense a pressure of the water in the flow path; andvii. a temperature sensor positioned in or near the flow path operable to sense a temperature of the water along the portion of the flow path where the heater is arranged; and wherein one or more of the spray valve, heater, pressure sensor, and temperature sensor are electrically connected to the controller;b. fluidly connecting the tankless beverage brewing apparatus to the local water supply via the inlet of the fluid path;c. reducing the water pressure from the local water supply via the pressure reducer positioned in the fluid path;d. activating the tankless beverage brewing apparatus and initiating a beverage brewing cycle for a desired beverage via a user interface;e. heating water in the flow path to a desired brew temperature of the desired beverage via the heater controlled by the controller, wherein the controller receives feedback from the temperature sensor connected thereto;f. controlling water flow rate from the water inlet of the flow path and out of a water delivery mechanism via the controller based on the desired beverage, wherein the controller is electrically connected to the spray valve positioned in the flow path to allow water to flow through the flow path, and wherein the controller is also electrically connected to the pressure sensor positioned in the flow path to adjust flow rate; andg. deactivating the heater and closing the spray valve at an end of a predetermined brew time of the desired beverage. 2. The method of claim 1 wherein the controller is operable for dynamically varying at least one of water temperature, flow rate, and quantity of water through the one or more water delivery mechanisms, by controlling at least one of the spray valve and heater. 3. The method of claim 2 wherein the controller dynamically varies one or more of water temperature and flow rate based on feedback from one or more of the temperature sensor and pressure sensor. 4. The method of claim 1 wherein the heater is controllable by the controller. 5. The method of claim 2 wherein the one or more water delivery mechanisms comprises at least one of a spray head and a spigot. 6. The method of claim 2 wherein the one or more water delivery mechanisms is electrically connected to the controller. 7. The method of claim 1 wherein the flow path further comprises an inlet line connected at the inlet to the local water supply at one end and coupled to an inlet of the pressure reducer at the other end; a main supply line coupled to an outlet of the pressure reducer at one end and coupled to an inlet of the spray valve at the other end; an outlet line coupled to an outlet of the spray valve at one end and coupled to an inlet of the one or more water delivery mechanisms at the other end. 8. The method of claim 1 wherein the pressure sensor is positioned in the flow path at a point between the pressure reducer and the one or more delivery mechanisms. 9. The method of claim 1 wherein the pressure sensor is positioned in the flow path at a point between the flow path inlet and the pressure reducer. 10. The method of claim 1 wherein the spray valve is at least one of electrically and manually controlled. 11. The method of claim 1 wherein the heater comprises a flow through on-demand heater. 12. The method of claim 1 further comprising a user interface electrically connected to the controller. 13. The method of claim 12 wherein the user interface comprises at least one of a display and user inputs. 14. The method of claim 13 wherein the user inputs comprise at least one of buttons or a touchscreen. 15. The method of claim 13 wherein the user via the user interface can at least one of turn the apparatus off and on, select a type of beverage to be brewed, select the quantity of beverage to be brewed, enter a brew temperature, initiate a brewing, suspend a brewing, program the apparatus, and check health and/or status information of the apparatus. 16. The method of claim 1 wherein the controller comprises at least one of a standard controller or a microprocessor device capable of executing program instructions. 17. The method of claim 16 wherein a beverage profiles file is programmed into the controller, wherein the beverage profiles file comprises at least one of brew flow rates and brew temperatures for different types and quantities of brew beverages. 18. The method of claim 1 further comprising a communications interface connected to the controller. 19. The method of claim 18 wherein the communications interface comprises at least one of a wired communications interface and wireless communications interface. 20. The method of claim 18 wherein the communications interface is operable for at least one of local and remote access to the controller, wherein the communications interface can be used to at least one of install software updates into the controller, update beverage profiles file, and monitor the health and/or status of the apparatus. 21. The method of claim 2 wherein the controller controls the heater using pulse-width modulation (PWM) to maintain a desired brew temperature. 22. The method of claim 2 wherein the controller can control the spray valve to create an intermittent water flow out of the one or more water delivery mechanisms. 23. The method of claim 2 wherein the controller dynamically controls the spray valve to vary length and number of pulses of water from the one or more water delivery mechanisms during a brewing cycle. 24. The method of claim 2 wherein at least one of the flow rate and temperature can be controlled independently for each of the one or more water delivery mechanisms. 25. The method of claim 1 wherein the flow path comprises a branch to form a second flow path connected to a second water delivery mechanism at its second end. 26. The method of claim 25 further comprising at least one of a second spray valve, second pressure reducer, second pressure sensor, second temperature sensor, and second heater, wherein the at least one of the second spray valve, second pressure reducer, second pressure sensor, and second temperature sensor are positioned in the second flow path and the second heater is positioned along a portion of the second flow path and thermally coupled thereto. 27. The method of claim 26 wherein at least one of the second spray valve, second pressure reducer, second pressure sensor, second temperature sensor, and second heater can be monitored and/or controlled independently, and therefore the flow rate and/or water temperature from the second water delivery mechanisms can be dynamically controlled by the controller independently.
