27. A method of manufacture of a cartridge for use in an aerosol-generating system, comprising:
-
providing a liquid storage portion comprising a housing; providing a heater assembly; placing a capillary material in the housing of the liquid storage portion, such that the capillary material is provided in direct contact with the heater assembly; and compressing a portion of the capillary material during or before the placing in the housing such that a porosity or pore size of the portion of the capillary material is reduced, wherein the provided liquid storage portion further comprises at least two parts in fluid communication with each other, the first part of the liquid storage portion comprising the capillary material, and the second part of the liquid storage portion comprising a container configured to hold a liquid aerosol-forming substrate and to supply the liquid to a region having a higher porosity or pore size of the capillary material.
