Abstract
Capsule (1A) designed in particular for the preparation of a beverage in a centrifugal brewing device by feeding liquid in the capsule and rotating the capsule along a central axis (I) to produce centrifugal forces on the liquid traversing the capsule thereby forcing the beverage out of the capsule by such centrifugal forces, wherein the capsule comprises: a body (2) comprising containment walls (3,4), a main opening (6) of central axis (I) closed by a closing wall (8) forming a compartment (7) including beverage ingredients and a flange (5) peripherally bordering the said opening (6), wherein it comprises a perforating wall (9) placed close to the closing wall (8) and comprising perforating means (10-15) for perforating the closing wall (8) when applying a pressure on the transversal closing wall (8) or perforating wall (9).
