Abstract: A coffeemaker (1) comprises a boiler (6) for heating water to a predetermined temperature, and a pump (4) for forcing a predetermined quantity of water to flow through a filter containing ground coffee beans. The coffeemaker is capable of making a single quantity and a double quantity of coffee. The volume of a container of the boiler is smaller than the volume of the total quantity of water required for obtaining the double quantity of coffee. During the process of making the double quantity of coffee, a first quantity of water is heated inside the boiler to the predetermined temperature and subsequently conducted through the coffee filter, whereupon a second quantity of fresh water is conducted through the coffee filter as well. The temperatures of the first quantity and the second quantity are different.
