ABSTRACT OF THE DISCLOSURE The coffee brewing machine can be used to prepare alter- natively normal coffee or espresso coffee and comprises a boi- ler having a temperature control. The cold water is fed to the boiler by means of a water pump with adjustable feed rate. Two different brewing members are used for the preparation of the two kind of coffees, namely a sieve holder and a filter support which are connectable via a mounting and supporting flange to the boiler. A mode switch is assigned to the mounting and sup- porting flange which automatically changes the mode of opera- tion of the coffee brewing machine upon exchanging the brewing member. Thereby, the feed rate of the water pump and the tem- perature of the hot water are adapted to optimize the condi- tions for preparing either normal coffee or espresso coffee.
