A water-vapor preparation system (S1) drives a stirring system (S2) with steam, and/or conveys steam or hot water to a brewing system (S0); the stirring system (S2) stirs foaming liquid under the drive of steam and makes it foam; a foaming and heating system (S3) receives the steam generated after the water-vapor preparation system (S1) drives the stirring system (S2) with steam or hot water formed by condensing the steam, and heats the foaming liquid in the stirring system; the brewing system (S0) receives the steam or hot water conveyed by the water-vapor preparation system (S1) to ferment or soak ground coffee therein to prepare coffee; and a control system (S4) is in a signal connection with and controls one or some of the water-vapor preparation system (S1), the stirring system (S2), the foaming and heating system (S3), and the brewing system (S0). According to the coffee maker, steam can be synchronously used for stirring to foam and heating. By means of stirring to foam, the foaming liquid has advantages of high foaming volume as well as adequate and fine foam. No motor is required to drive the stirring system, and therefore, both the setup cost and operating energy consumption are low.
