1. A capsule for the preparation of a beverage by centrifugation in a beverage preparation device, the capsule comprising:
a generally concave outer wall and a generally concave inner wall, each wall having a peripheral portion extending substantially revolutionary around a central axis and a bottom portion; a lid extending transversally to said central axis and covering said outer and inner walls and forming with said inner wall an inner cavity containing beverage ingredients, an outer cavity positioned between the inner and outer walls; wherein beverage outlets or outlet precursors are positioned exclusively on the peripheral portion of the inner wall at or in the vicinity of a largest radius thereof to enable the beverage to be displaced from the inner cavity to the outer cavity through the beverage outlets or outlet precursors under the effect of centrifugal pressure, said outer cavity thereby collecting the beverage coming from the inner cavity, and wherein a remainder of the inner wall that does not form the peripheral portion thereof is free of beverage outlets or outlet precursors.
