1. A method for dispensing ground coffee for preparing a coffee beverage, the method comprising:
providing a machine, which comprises one or more receptacles for storing one or different types of roasted coffee beans, one or more dosing devices each including two counter-rotating cylinders arranged to rotate towards an inner center for dispensing the coffee beans from the one or more receptacles to a location between the two counter-rotating cylinders, wherein the two counter-rotating cylinders are at least in part made of a compressible or soft material having a hardness less than a hardness of the coffee beans, wherein the compressible or soft material provides a tight outlet that prevents air from entering the one or more receptacles, wherein each of the one or more dosing devices is configured to act as a pump or as a reverse pump in dispensing the coffee beans, and a grinder for receiving the coffee beans, which are dispensed by the one or more dosing devices, the grinder being configured to move into different grinding positions for different grinding degrees, respectively,
setting up the grinder so that the grinder is in a specific grinding position,
dispensing, with the one or more dosing devices, a specific amount of the coffee beans to the grinder subsequent to the setting up of the grinder, and
grinding, with the grinder, said specific amount of the coffee beans and, thus, dispensing the ground coffee beans until the grinder is free from coffee beans.
