A capsule, system and method are usable for preparing a predetermined quantity of beverage using an extractable product. The system includes a capsule comprising a cup having a circumferential wall, a bottom at a first end, and a flange-like rim at a second end. The capsule further includes a lid, in use, connected to the flange-like rim. The wall, bottom and lid, in use, enclose an inner space comprising the extractable product. The cup further includes a plurality of substantially concentric circumferential ridges extending outwardly of the cup, wherein the ridges are made of the same material as the cup. The system further includes a beverage brewing device comprising an enclosing member for enclosing the capsule. In use, at least one of the ridges abuts against at least a portion of the enclosing member, such that a sealing engagement between the capsule and the enclosing member is formed. |
