The aerosol-generating article is capable of being used with an electrically-operated aerosol-generating device. The aerosol-generating article is a consumable article having an outlet end, a distal end upstream from the outlet end, and a mid-point located an equal distance between the outlet end and the distal end. The article includes a first volatile liquid substrate contained within a first frangible capsule, the frangible capsule being located between the distal end and the mid-point, and a second volatile liquid substrate contained within a second frangible capsule, the second frangible capsule being located between the distal end and the mid-point. The article also includes a liquid retention medium, at least a portion the liquid retention medium being located between the distal end and the mid-point, wherein the article is configured to allow air to be drawn through the article from the distal end to the outlet end.

A flavor delivery article is provided including a substantially rod-shaped carrier element and a wrapping element. The wrapping element surrounds at least a portion of the carrier element. The delivery article includes a flavor material within one or both of the carrier element and the wrapping element. The flavor delivery article is adapted for delivery of the flavor material to the mouth of a user under mouth conditions in the absence of combustion or other external heating.
