Kit for the preparation of a beverage in a centrifugal brewing device

A kit to be inserted in a centrifugal brewing device, the kit comprising:

• a capsule configured for preparation of a beverage in the centrifugal brewing device by feeding liquid in the capsule and rotating the capsule along a central axis to produce a centrifugal force on the liquid traversing the capsule to force the beverage out of the capsule by the centrifugal force, and
• the capsule comprises containment walls forming a main cavity of the central axis;
• and
• the kit further comprising an insert independent from the centrifugal brewing device and which is separate from the capsule,
• the insert comprises a ring-shaped portion forming a valve engaging portion configured for engagement against a valve means of the centrifugal brewing device,
• the insert further comprises a transversal annular or circular portion which is inwardly and integrally connected to the ring-shaped portion,
• the insert is hollow at and around the central axis, the transversal annular or circular portion has one or more through-openings for allowing liquid to flow through the insert, and the insert is configured to allow gas to flow through the insert and into the capsule prior to insertion of the kit in the centrifugal brewing device, and
• the ring-shaped portion extends axially above and below the transversal annular or circular portion to form a “T” in transversal cross section, the ring-shaped portion has an outer diameter larger than the largest diameter of the capsule, and the ring-shaped portion has a structure in relief and/or recess on an upper surface thereof, the structure configured to create beverage radial flow passages during centrifugation.
