Abstract
A capsule for the production of a beverage in a beverage production machine comprising a capsule holder with relief and recessed elements. The capsule includes an inverted cup-shaped body forming a chamber containing beverage ingredients; a bottom injection wall; a sidewall; and a delivery wall which is sealed to the body. The delivery wall is configured and dimensioned to include a calibrated orifice or perforating means to provide a calibrated orifice with the beverage delivery wall not being tearable against the capsule holder during extraction. The wall also provides through the restriction created by the calibrated orifice a certain back pressure which generates an elevated pressure in the capsule during extraction. Also, a system and method for producing a beverage from the capsules of the invention.
