A dispenser group for a coffee maker comprises an upper part (1; 1'), a piston (4; 4') inside the upper part, a lower part (2; 2') that can be inserted in and extracted from the upper part, partially or totally, and a lever (7; 7') pivotally fixed to the upper part. The piston comprises two guides (4.3; 4'.3) defined on different, normally opposite, inner walls thereof, so that a moving shaft (6; 6') of the lever can be engaged with said guides and, upon the rotation of the lever, the piston can be axially displaced. The lower part comprises a seat for placing a coffee dose, so that, after the lower part has been inserted and the lever has been lowered, the piston and the seat are joined to define a chamber for brewing a coffee.
