<p>A capsule designed for insertion in a centrifugal beverage production device for preparing a beverage from a substance contained in the capsule by introducing liquid in the capsule and passing liquid through the substance using centrifugal forces. The capsule has a body with bottom and open ends that are spaced apart in the axial direction, an upper wall for covering the body at its open end along a direction transverse to the axial direction, and an enclosure between the body and upper wall containing a predetermined amount of beverage substance. The capsule also includes an annular pressure-setting ring configured for adjusting the backpressure in the beverage production device. The pressure-setting ring provides improved quality of in-cup coffee. Also, a set of capsules having pressure-setting rings of different dimensions is provided for setting different backpressure when the capsules are engaged in a centrifuging beverage production device.</p> |
