Abstract

In a method for producing coffee, coffee beans are ground very finely, with or without the addition of water, and a mixture of the coffee powder and water is formed, and the coffee is extracted from this mixture and preferably conveyed to an outlet. Coffee beans and the water in the grinding chamber can be supplied to at least one mill, and the coffee beans ground with the water supplied, and the mixture formed from this. To form the mixture, cold or hot water is supplied to the mill during the grinding process in the grinding chamber and/or after the grinding process. Thus, the coffee produced has an especially full-bodied flavor.
