1. A method of making a beverage from powdered material in a cup-shaped sealed capsule (2), the method comprising the steps of inserting a said sealed capsule (2) between pressurized-hot-water dispensing means (11) and a cup (42) aligned with the dispensing means (11) along a horizontal axis (9), the insertion step being carried out by feeding the sealed capsule (2) downwards along an inlet conduit (52) into a first seat (67) defined between two elastically deformable jaws (63), and applying downward thrust to the sealed capsule (2) inside the first seat (67) to part the two jaws (63) and transfer the sealed capsule (2) from the first seat (67) to a second seat (68) coaxial with said axis (9) and also defined by said two jaws (63);

  • and the method further comprising the steps of piercing a sealing wall (6) fitted integrally to an outer annular flange (4) of the sealed capsule (2) by applying an axial force to said flange (4) and pushing the sealed capsule (2), still coaxial with said axis (9), axially against a first piercing device (21) carried by the dispensing means (11); and

    piercing an end wall (5) of the sealed capsule (2) opposite to the sealing wall (6) by applying axial compression to the sealed capsule (2) to push the end wall (5) against a second piercing device (44) carried by the cup (42);

    the axial compression being applied only after feeding pressurized hot water into the sealed capsule (2) through the pierced sealing wall (6).
