A method for producing a coffee beverage in a coffee machine that allows consistent brewing temperatures by preheating the brewing chamber. The method involves supplying a first quantity of heated fluid through the brewing chamber feed line before brewing, discharging some of it, then brewing with a second quantity. This preheats the chamber without losing heat in the feed line. Alternatively, moving the brewing piston closer to the chamber end before preheating. This ensures the feed line fluid has higher temperature when it enters the chamber.

A coffee machine that allows precise control of water temperature during brewing and adapts to environmental conditions like altitude and barometric pressure. The machine has a water pump, heating element, and temperature sensor. It estimates the temperature reduction through the heating element based on ambient conditions. It pumps water to fill the element when hot, then disables the pump until it reaches the brewing temperature. It adjusts pump voltage to achieve the desired brewing temperature. This compensates for altitude effects that lower boiling points. If actual temperature reduction differs, it recalculates throughput and voltage. The heating element has layers of metal and silicone for water flow.
