1. A brewing apparatus for extracting a portion capsule, comprising a first brewing chamber element and a second brewing chamber element, wherein the first or the second brewing chamber element is movable in an axial direction between a loading position, in which the first and the second brewing chamber elements are spaced apart from each other, and an extraction position, in which the first and the second brewing chamber elements form a substantially closed brewing chamber, wherein, upon movement of the first or the second brewing chamber element from the loading position into the extraction position, the portion capsule is first perforated by at least one first perforation means of the first brewing chamber element and then is perforated by at least one second perforation means of the second brewing chamber element, the first brewing chamber element has a perforation element which comprises a base surface and the at least one first perforation means formed on a peripheral region of the base surface in a circumferential direction, the at least one first perforation means has a linear cross section which is bent along a circumference of the base surface to protrude perpendicularly from the peripheral region of the base surface, the at least one first perforation means being positioned at a constant radius about a central point of the base surface, the at least one first perforation means cooperates with an edge region of the portion capsule to ensure a more reliable perforation operation, wherein liquid flows at angles through the portion capsule to increase an interaction distance and interaction time between the liquid and contents of the portion capsule. 2. The brewing apparatus as claimed in claim 1, wherein the base surface faces the second brewing chamber element, wherein the first brewing chamber element has a plurality of first perforation means which are arranged below a horizontal plane with a substantially constant radius about the central point of the base surface. 3. The brewing apparatus as claimed in claim 2, wherein the first brewing chamber element has a plurality of first perforation means for perforating the portion capsule, wherein the first perforation means are arranged within an angular range of at maximum 230 degrees about the central point. 4. The brewing apparatus as claimed in claim 1, wherein the first brewing chamber element comprises at least four first perforation means. 5. The brewing apparatus as claimed in claim 1, wherein the brewing apparatus is designed in such a manner that, upon movement of the first or the second brewing chamber element from the loading position into the extraction position, the portion capsule is perforated substantially sequentially by a plurality of first perforation means of the first brewing chamber element. 6. The brewing apparatus as claimed in claim 1, wherein, in the loading position, the portion capsule is fed in a loading direction between the first and the second brewing chamber elements, wherein a cutting plane of the at least one first perforation means is oriented substantially at a right angle to the loading direction. 7. The brewing apparatus as claimed in claim 1, wherein the first brewing chamber element and the perforation element has a plurality of water outlet openings in a surface region for feeding extraction liquid into the portion capsule perforated by means of the at least one first perforation means, wherein, one water outlet opening is in each case arranged substantially adjacent to the at least one first perforation means. 8. The brewing apparatus as claimed in claim 1, wherein the second brewing chamber element comprises a hollow bell-shaped element for receiving the portion capsule, wherein a base region of the bell-shaped element comprises at least one depression for conducting away extraction liquid from the portion capsule perforated by means of the second perforation means, wherein the second perforation means is arranged in a region of the depression, and wherein the depression leads into a drainage channel for removing the extraction liquid from the brewing chamber. 9. The brewing apparatus as claimed in claim 1, wherein, in the loading position, the portion capsule is fed in a loading direction between the first and the second brewing chamber elements, wherein the loading direction is oriented at a right angle to a horizontal plane, wherein the first brewing chamber element has at least one first perforation means for perforating the portion capsule, and in that the brewing apparatus has a spacing element which is designed in such a manner that, when the portion capsule is fed between the first and the second brewing chamber elements in the loading position, mechanical contact between the portion capsule and the at least one first perforation means is prevented by the spacing element, wherein the spacing element comprises a metal strip, wherein the metal strip has a first end which is fastened to the first brewing chamber element and a second, free end, wherein, in the loading position, the second end protrudes from the first brewing chamber element obliquely in a direction of the second brewing chamber element, or, in the loading position, bears against a surface of the first brewing chamber element, which surface faces the second brewing chamber element, wherein the metal strip at least has a curvature in the direction of the second brewing chamber element, has a passage hole or is oriented substantially parallel to the loading direction. 10. The brewing apparatus as claimed in claim 9, wherein the first brewing chamber element comprises at least one first perforation means in the form of perforation points, wherein the spacing element is at least partially arranged between at least one perforation point, and wherein, in the loading position, the spacing element is spaced apart from the first brewing chamber element at least in a region between the perforation points, and wherein the perforation points are arranged in a gravitational field below a horizontal plane. 11. The brewing apparatus as claimed in claim 9, wherein the spacing element is fastened to the first brewing chamber element and is at least partially pretensioned elastically in the direction of the second brewing chamber element, or in that the spacing element is designed in such a manner that, in the extraction position, said spacing element bears substantially completely against the first brewing chamber element.
