A coffee capsule is provided, the outer dimensions of which are matched to the size of a filtered-coffee capsule, but which has a separating element that separates an empty area from an extraction-material area. Furthermore, at least one liquid channel is provided, which passes through the empty area for example. The liquid channel or liquid channels and the extraction-material area are designed in such a way that water introduced into the capsule at an injection location or a beverage produced in the capsule substantially does not enter the empty area.

The portion capsule according to claim 1, wherein the at least one liquid channel traverses the empty region. 3. The portion capsule according to claim 2, wherein the at least one liquid channel is in the form of a pipe. 4. The portion capsule according to claim 1, wherein the separation element is formed by an insertion part, which is inserted into a capsule body, which is closed by a lid. 5. The portion capsule according to claim 4, wherein the insertion part comprises at least one extension, which projects away from the separation element, in the form of a hollow body, which extends as far as the outer wall and forms the at least one liquid channel, wherein the extension is connected, adhesively bonded or welded, to the outer wall. 6. The portion capsule according to claim 4, wherein the insertion part comprises a peripheral wall, which, together with the separation element, forms a cup-like structure, which is filled with at least some of the extraction material. 7. The portion capsule according to claim 4, wherein the insertion part comprises a seal tab, which is pressed against the outer wall by an elevated pressure in the extraction material region. 8. The portion capsule according to claim 7, wherein the outer wall is formed by a capsule body and a lid closing said capsule body, wherein the seal tab is clamped between the capsule body and the lid. 9. The portion capsule according to claim 1, wherein the empty region is hollow, apart from the at least one liquid channel and any reinforcements. 10. The portion capsule according to claim 1, wherein the separation element comprises a plurality of passage openings, which connect the extraction material region to the at least one liquid channel, wherein the passage openings taper in a conical manner in the direction of the liquid channel. 11. A beverage preparation system, comprising: a beverage preparation machine with a brewing chamber, capable of receiving a portion capsule, which can be pierced by injection-side piercing means and extraction-side piercing means of the beverage preparation machine, and with a liquid pump for delivering hot water into the brewing chamber and through the injection-side piercing means into the portion capsule,a first capsule with a first extraction material region, which is filled with extraction material, wherein the first extraction material region comprises a first volume, anda second capsule with a second extraction material region, which is filled with an extraction material, wherein the second extraction material region comprises a second volume,wherein external dimensions of the first capsule are substantially identical to external dimensions of the second capsule, and wherein the dimensions of capsules of both types are aligned to the brewing chamber,wherein the second capsule is a portion capsule including an outer wall and wherein the second extraction material region, is arranged in the capsule interior, wherein an empty region is present in the capsule interior, said empty region being separated from the extraction material region by a separation element, which is likewise present in the capsule interior, and wherein at least one liquid channel is also present in the capsule interior in such a way that liquid, which is introduced into the capsule at an injection location, comes into contact with the extraction material and can be discharged from the capsule at a point, which is not the injection location, substantially without the liquid entering the empty region and whereinthe first volume is greater than the second volume. 12. A beverage preparation system, comprising a beverage preparation machine with a brewing chamber capable of receiving a portion capsule, which can be pierced by injection-side piercing means and extraction-side piercing means of the beverage preparation machine, and with a liquid pump for delivering hot water into the brewing chamber and through the injection-side piercing means into the portion capsule,a first type of capsule with a first extraction material region, said first extraction material region having an available first volume to receive extraction material, said first extraction material region receiving a first amount of extraction material in said first available volume, anda second type of capsule with a second extraction material region, said second extraction material region having a second available volume to receive extraction material, said second extraction material region receiving a second amount of extraction material in said second available volume,wherein external dimensions of coffee capsules of the first type of capsule are substantially identical to external dimensions of capsules of the second type of capsule, and wherein the dimensions of capsules of both types are aligned to the brewing chamber,wherein the first available volume of said first type of capsule is greater than the second available volume of said second type of capsule. 13. The beverage preparation system according to claim 12, wherein a pumping pressure of the delivery pump can be switched over between at least two different operating conditions. 14. The beverage preparation system according to claim 12, wherein the first available volume is at least 25 ml. 15. A portion capsule for a brewed beverage, comprising: an outer wall, a separation element, and an extraction material region, said extraction material region being defined between the outer wall and the separation element in the capsule interior and being filled with an extraction material,wherein an empty region is present in the capsule interior, said empty region being defined between the outer wall and the separation element and being separated from the extraction material region by the separation element, andwherein at least one liquid channel is also present in the capsule interior and extends from said outer wall to said separation element, said at least one liquid channel and said separation element are integrally connected to one another to form a unitary structure such that, in use, the separation element and liquid channel are immovably affixed to one another and cooperate to direct liquid, which is introduced into the extraction material region at an injection location and flows through the extraction material region to a discharge point via the at least one liquid channel, such that the liquid comes into contact with the extraction material and is discharged from the capsule at the discharge point, while substantially preventing the liquid from entering the empty region, and wherein said discharge point is different from the injection location. 16. The portion capsule according to claim 15, wherein the at least one liquid channel traverses the empty region. 17. The portion capsule according to claim 16, wherein the at least one liquid channel is in the form of a pipe. 18.
