Abstract
A capsule is 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 the liquid through the substance using centrifugal forces. The capsule includes a body having a bottom end and an open end spaced apart in the axial direction, an upper wall for covering the body at the open end along a direction transverse to the axial direction, and an enclosure between the body and the upper wall containing a predetermined amount of beverage substance. The capsule further includes an annular pressure-setting ring configured for adjusting the backpressure in the beverage production device. The pressure-setting ring provides an improved coffee in-cup quality. A set of capsules can have pressure-setting rings of different dimensions for setting different backpressure when engaged in a centrifuging beverage production device.
