1. A method for automatically producing a coffee preparation by means of a coffee preparation device (1), which comprises a brewing unit, comprising the following steps: (a) inserting a cartridge (3), which is prefilled with a powder supply (4) of ground coffee beans, which is compressed and which comprises a plurality of powder portions (11), into a cartridge accommodation (2) of a preparation device (1);(b) metering of a powder portion (11) from the powder supply (4), wherein the entire powder supply (4) is displaced for this purpose, axially displaced, with the help of metering means (10), and the powder portion (11) is then separated from the powder supply (4), the metering means (10) comprise an automatically drivable compression plunger (6), which is moved for metering the powder portion in the cartridge (3) and which thereby presses on one of (a) directly on the powder supply (4), (b) directly on a deformable or displaceable cartridge section, and (c) to displace the entire cartridge (3);(c) transferring the powder portion (11) to a brewing unit of a preparation mechanism (16);(d) automatic preparation of the coffee in the brewing unit using the powder portion (11) and a heated, drinkable liquid, which flows through the powder portion in the brewing unit under pressure;(e) sealing the cartridge (3) in the area of an outlet opening (5) of the cartridge in the preparation device. 2. The method according to claim 1, wherein the cartridge (3) is sealed with the help of sealing means (9) after removing the powder portion (11). 3. The method according to claim 1, wherein a capsule volume, which surrounds the powder supply (4), is changed by and/or in response to the metering of the powder portion (11) such that the capsule volume, after removing the powder portion (11) at least approximately corresponds to the powder supply (4), which remains in the capsule, reduced by the removed powder portion (11). 4. The method according to claim 1, wherein the powder portions (11) are separated in one piece from the powder supply (4) and/or are transferred to the preparation mechanism (16). 5. The method according to claim 1, wherein the powder quantity of the powder portion (11), which is to be removed, can be adjusted. 6. The method according to claim 1, wherein the metering means (3) comprise shearing means for separating from the powder supply (4) by applying pressure for a powder portion (11) to be metered. 7. The method according to claim 6, wherein the powder portion (4) is supplied to the preparation mechanism (16) together with the cartridge. 8. The method according to claim 7, wherein the cartridge (3) is sealed by means of the shearing means (15) or by means of a sealing part, which is operatively connected to the shearing means (15). 9. The method according to claim 6, wherein the powder portion (11) is transported in the direction towards the preparation mechanism (16) with the help of transport means (14), which comprises the shearing means (15). 10. The method according to claim 9, wherein the cartridge (3) is sealed with the help of the transport means (14) or by means of a sealing part. 11. The method according to claim 1, wherein, prior to removing the powder portion (11), one of a plurality of cartridges (3), which are accommodated in a preparation device (1), is selected, from which the powder portion (11) is then removed. 12. The method according to claim 1, wherein, prior to removing a first powder portion (11), an aroma seal is removed. 13. The method according to claim 1, wherein the cartridge (3) is stored and cooled under an inert gas atmosphere. 14. The method according to claim 1, wherein at least one further powder portion (11) from the same powder supply (4) is metered in the preparation device (1) and is processed in the preparation mechanism (16) for food preparation. 15. The method according to claim 1, wherein, for preparing the coffee, a milk powder portion is metered from a milk powder cartridge, which is prefilled with a milk powder supply, which is compressed and which comprises a plurality of milk powder portions, and is mixed with water and/or water vapor, and is heated and/or frothed, and/or that a portion of cacao from a cacao powder cartridge, which is prefilled with a cocoa supply, which is compressed and which comprises a plurality of cocoa powder portions, is metered for preparing the coffee. 16. A coffee preparation device (1) for the automatic production of a coffee, comprising a cartridge accommodation (2) for a cartridge (3), which is prefilled with a powder supply (4) of ground coffee beans, and which comprises a plurality of powder portions (11), metering means (10) for metering a powder portion (11) from the powder supply (4) by displacing the entire powder supply (4) with the or relative to the cartridge (3) and separating the powder portion (11) from the powder supply (4), a heating device for heating at least one drinkable liquid, a preparation mechanism (16), which comprises a brewing unit and which is embodied for preparing the coffee using the powder portion (11) and the heated liquid, as well as sealing means (9) for sealing the cartridge (3), in the area of a cartridge outlet opening (5), wherein the metering means (10) comprise an automatically drivable compression plunger (6), which is adapted to move relative to the sealing means so as to do one of (a) insert into the cartridge (3), (b) displace the cartridge, and (c) deform a cartridge section. 17. The device according to claim 16, wherein the metering means (10) are embodied such that a cartridge volume, which surrounds the powder supply (4), is changed by means of said metering means, in response to the metering of the powder portion (11) such that, after removing the powder portion (4), the cartridge volume corresponds at least approximately to the powder portion (11), which remains in the cartridge (3), reduced by the removed powder portion (4). 18.
