A mouthpiece for an aerosol-generating article, the mouthpiece comprising a housing with
- an inlet end, configured to allow an aerosol to flow into the mouthpiece,
- an outlet end, configured to allow the aerosol to flow out of the mouthpiece, and
- an aerosol flow path extending between the inlet end and the outlet end,
- wherein the mouthpiece is formed such that the flow direction of the aerosol is reversed at least once between the inlet end and the outlet end, and
- wherein the mouthpiece is formed from an outer part and an inner part, wherein the outer part forms a central inner channel and a tubular outer wall of the mouthpiece, and wherein the inner part has a hollow tubular shape with a side wall, one open end face and one closed end face, wherein the inner part is axially inserted from the outlet end side into the outer part in such a way that the side wall of the inner part is located between the central channel and the outer wall of the outer part.
