A coffee machine for making a coffee beverage by means of pre-packed and pre-portioned coffee pouches ( 10 ) comprises a brew chamber which includes a brew chamber top ( 3 ) and a brew chamber base ( 9 ). The brew chamber top ( 3 ) is movable by a locking mechanism along a virtual vertical axis from an elevated position to a position lowered on the brew chamber base ( 9 ) to form a tight brew chamber and is movable back into the elevated position where a carrier ( 8 ) of brew chamber base ( 9 ) can be pushed, in horizontal plane from a pushed-in position in which the brew chamber base ( 9 ) and the brew chamber top ( 3 ) are disposed coaxially relative to each other, into a drawn-out position in which a pouch ( 10 ) can be placed on said brew chamber base ( 9 ). Piercing elements are supported at said brew chamber top ( 3 ) and can be pushed into its interior. An actuation mechanism of the piercing elements is coupled to the locking mechanism of the brew chamber so that after lowering the brew chamber top ( 3 ) and thus locking the brew chamber, the actuation mechanism pushes said piercing elements into the interior of brew chamber top ( 3 ). After elevating the brew chamber top and thus opening the brew chamber and drawing out the movable carrier ( 8 ) the piercing elements are withdrawn from the interior of the brew chamber top.
