It has also surprisingly been found that the turbidity of the beverage produced is considerably reduced if, for example, the raw material comprising a beverage raw material is arranged inside the liquid-permeable casing element located in the base element.
  • the casing element is preferably made of a liquid-permeable material, so that the extraction liquid entering the brewing chamber can thus emerge from the area of the beverage raw material at any point of the casing element, so that in contrast to the portion-capsules known from the prior art in the region of the beverage raw material no increased pressure through a filter medium occurs.
  • the beverage liquid emerging from the casing element can immediately relax outside the casing element and flow in the direction of the capsule bottom in order to emerge there from the portion capsule.

  • the casing element completely envelops the raw material.
  • the area through which the extraction liquid can escape from the region of the raw material is thus increased and the pressure in the area of the raw material is further reduced. The foaming is thereby effectively avoided.
  • the casing element is made of a porous and pliable material.
  • the porosity of the casing element results in that no appreciable pressure increase in the area of the raw material occurs through the casing element.
  • the water can flow through the Hüllelements almost unhindered, while the raw material is retained, so that no contamination of the beverage by particles of the raw material takes place.
  • a drainage of the liquid, in particular of the beverage or of the cleaning liquid, is also made possible between the wall of the base element and the casing element possibly adjacent to the wall in the direction of the capsule bottom.
