Abstract

The method includes first providing a retention medium in a first element; coaxially aligning a plurality of elements, wrapping the coaxially aligned plurality of elements within a wrapper to form a portion of the aerosol-generating article, the plurality of elements including the first element, the aerosol-generating article having a first end and a second end, the second end being upstream from the first end based on an expected direction of airflow through the aerosol-generating article during normal operational use, second providing at least one capsule, the at least one capsule releasably containing a substrate, and inserting the at least one capsule within the first element, the retention medium being configured to retain the substrate after a release of the substrate from the at least one capsule, the retention medium being devoid of the substrate prior to the release of the substrate from the at least one capsule.
