A tankless beverage brewing apparatus that includes a digital controller for dynamically varying the water temperature and/or the brew flow rate of the dispensed beverage is disclosed. In some embodiments, a main supply line of the tankless beverage brewing apparatus includes a pressure reducer, a pressure sensor, a linear heater, a temperature sensor, and a spray valve all supplying a hot water spray head and/or a hot water spigot. The inlet of the main supply line of the tankless beverage brewing apparatus may be connected directly to the local cold water supply. The controller uses feedback from the temperature sensor and/or the pressure sensor to dynamically vary the water temperature and/or the brew flow rate depending on the type of beverage being brewed.
