Claim Text:
1. A method for brewing coffee in a coffee machine including a water reservoir, a heating element, a water pump, and a coffee flask with a filter holder positioned above the coffee flask, the method comprising: measuring an ambient temperature in the coffee machine with a temperature sensor; estimating a temperature reduction of water from the heating element to the filter holder using a predefined model; providing power to the heating element, the heating element heating water from the water tank, the water then passing from the heating element through a conduit to the filter holder; when a temperature of said heating element reaches a first predefined temperature, activating the water pump for a first time interval until the heating element is filled with water; disabling the water pump for a second time interval until the temperature of the water in the heating element has reached a second predefined temperature; estimating a throughput level in the heating element that provides a predefined output temperature of the water when the water contacts ground coffee beans contained in the filter holder, the throughput level being based on the estimated temperature reduction and measured ambient temperature; and activating the water pump with a voltage level that provides the estimated throughput level.
