A device for preparing espresso coffee by means of a measure of loose ground coffee or a measure of ground coffee contained in a capsule (24) which is provided with a sealing edge (23) and at least one predetermined breaking zone (26), comprising at least one dispensing group (1), the dispensing group being provided with a recess (1a) which has a circular cross-section and is provided at the bottom with a perforated disk (4) for distributing the pressurized hot water. The device further comprises a filter holder (7) which can be connected to the recess (1a) of the dispensing group, the filter holder (7) being provided with a recess (6), and a bottom (12) having a channel (13) for dispensing the drink, a filter container (5) suitable for being received in the recess (6) of the filter holder (7) when the coffee is prepared from a measure of loose ground coffee and for being removed from the filter holder (7) when the coffee is prepared from a measure of ground coffee contained in a capsule (24). The perforated disk (4) for distributing the pressurized hot water extends radially in the bottom of the recess (1a) of the dispensing group (1) with an annular zone (15) which is not provided with holes and which faces the filter holder (7), the width of that annular zone (15) being capable of constituting an axial sealing support with respect to the edge (23) of the capsule (24).
