Please replace the present Abstract with the following Abstract. A method for extracting coffee with a coffee machine, where the machine memorizes a plurality of selectable extraction cycles, the method including among other things, detecting a temperature value along an infusion circuit, comparing the detected temperature value with an extraction start temperature value of the selected extraction cycle, performing a heat regulation step by activating the supply pump and, if necessary, the electric heater, for generating a heat regulation water flow until the detected temperature value reaches the extraction start temperature value of the selected extraction cycle, and performing the extraction step cyclically by activating the supply pump and by activating the electric heater at least when an extraction cycle is selected which envisages maintaining or increasing the extraction temperature from the extraction start temperature value.
A method for extracting coffee with a coffee machine comprising an infusion circuit at least including a water tank or a connection to a water source, a supply pump, an electric heater and an infusion unit having an infusion chamber where a load of coffee powder can be positioned, connected in sequence, wherein said machine memorizes a plurality of selectable extraction cycles, where each extraction cycle includes a step dedicated to the heat regulation of the infusion circuit before the positioning of the load of coffee powder and subsequently a step dedicated to the extraction of coffee having a specific coffee extraction start temperature value, where the dedicated extraction step further envisages a specific amount of coffee extracted and a specific extraction profile which envisages the repetition of identical activation cycles of the supply pump until reaching the specific amount of extracted coffee, where the cycles are each formed by an on time and an off time of the supply pump, and where the coffee machine, after having acquired a coffee extraction cycle selection, detects the temperature value along the infusion circuit, compares said detected temperature value with the extraction start temperature value of the selected extraction cycle, performs the heat regulation step by activating the supply pump and, if necessary, the electric heater, for generating a heat regulation water flow until said detected temperature value reaches said extraction start temperature value of the selected extraction cycle, and performs the extraction step cyclically by activating the supply pump and by activating the electric heater at least when an extraction cycle is selected which envisages maintaining or increasing the extraction temperature from the extraction start temperature value.
