The brewing apparatus (1) comprises a guide and support structure (2), and bears a movable receiving assembly (7) provided with a receptacle (9) capable of receiving a capsule (10) or similar, containing a quantity or measure of a substance for the preparation of a beverage, and a substantially stationary cooperating assembly (6); the movable assembly (7) being able to assume a closed position in which it is coupled with the cooperating assembly (6) to define a brewing chamber able to contain a capsule (10), and a separated open position. The cooperating assembly (6) is able to inject water and/or steam into the brewing chamber. An ejection device (20) is provided to eject a used capsule (10) from the region between said assemblies (6, 7) when, after the beverage has been prepared, the movable assembly (7) returns from the closed position to the open position.The ejection device includes an ejecting member (20) mounted pivotingly on the movable assembly close to the receptacle (9) along a path intersecting that region, between an idle position in which it allows a capsule (10) to be inserted into said region, and a working position in which it is able to push a used capsule (10) downwards to eject it from said region, a control mechanism (24; 26-34) on the structure (2) cooperating with the movable assembly (7) to cause the ejecting member (20) to move from the idle position to the working position each time the movable assembly (7) is in a predetermined position when returning to the open position.
