Claim:
A system for preparing a predetermined quantity of beverage suitable for consumption using an extractable product, the system comprising: an exchangeable capsule; and an apparatus comprising a fluid dispensing device for supplying an amount of a fluid, under a pressure of at least six bar to the exchangeable capsule, and a receptacle for holding the exchangeable capsule; wherein the exchangeable capsule comprises: a circumferential first wall, wherein the circumferential first wall is frustoconical, a second wall closing the circumferential first wall at a first end, wherein the second wall is integral with the circumferential first wall, a flexible sheet-shaped perforate and/or porous third wall closing the circumferential first wall at a second, open, end opposite the second wall, and an outwardly extending rim, wherein the third wall is attached to the outwardly extending rim, wherein the first, second, and third wall enclose an inner space comprising the extractable product, wherein the third wall forms an outermost boundary of the capsule in an axial direction thereof, and wherein the third wall comprises filtering paper or a nonwoven filtering material; wherein the fluid dispensing device is arranged for supplying the fluid to the extractable product under the pressure of at least six bar through the second wall for forming the beverage; wherein the receptacle comprises a support surface, and the third wall is arranged to abut against the support surface for draining the prepared beverage from the capsule through the third wall and through the support surface; wherein the support surface comprises an abutting area intended for said abutment with the third wall, which abutting area comprises ridges having a substantially non-straight form; wherein channel shaped grooves are formed between the ridges in a side of the support surface facing the third wall, for draining the prepared beverage from the capsule through the grooves; wherein the ridges have a convex top; wherein the ridges comprise edges; wherein the edges are not sharp; and wherein the edges have a radius of curvature of at least 50 μm.
