A single-use capsule for preparing a food liquid from a food substance contained in the capsule by introducing water in the capsule and passing water through the substance using centrifugal forces for producing the food liquid which is centrifuged peripherally in the capsule relatively to a central axis (A) of the capsule. The capsule includes an enclosure containing a predetermined amount of food substance, and a plurality of outlet openings for enabling the food liquid to leave the enclosure under the centrifugal forces exerted in the capsule, with the outlet openings being arranged at a substantially peripheral portion of wall of the capsule.
