The invention relates to a smoking article having a cylindrical shape with a longitudinal axis running through respective base areas of a distal end and a mouth end of the smoking article. The smoking article segments are at least in part wrapped in a circumferential wrapper and arranged subsequently in from the distal to the mouth end as follows: a. a tobacco segment comprising tobacco or tobacco derived smokable material, b. a cooling segment having a first flow path from the tobacco segment to a filter segment, c. the filter segment comprising a second flow path from the cooling segment to the mouth end.

The filter segment comprises a tobacco product including tobacco particles having an average particle size of 30 m and a dispersion medium for dispersing the tobacco particles. The invention also comprises a method for manufacturing such a smoking article.

A tobacco smoke filter or filter element including a longitudinally extending core of tobacco smoke filtering material of circumference 14 to 17 mm which includes a channel which extends longitudinally from an end of the core; wherein the core further includes a plasticiser in an amount of 17 to 19% by weight of the tobacco smoke filtering material.

A filter segment for use in a filter of a smoking article includes a substrate loaded with at least one smoke-modifying agent. The substrate is located within the body of the filter segment and is formed from filter plug wrap having an air permeability ranging from about 6,000 Coresta units to about 24,000 Coresta units.

A tobacco extract sheet, a method of producing the same, and a smoking article including the same are provided. The tobacco extract sheet according to some embodiments of the present disclosure may be produced from a sheet-producing liquid which includes a first tobacco extract solution, a second tobacco extract solution, and a sheet-forming agent, wherein the first tobacco extract solution may include water as an extraction solvent, and the second tobacco extract solution may include a material other than water as an extraction solvent. The tobacco extract sheet produced in this way may be applied to a smoking article and may significantly improve persistence of a tobacco smoke taste of the smoking article.

A capsule for use in a smoking article includes a liquid sensory enhancing material; and a shell surrounding the liquid sensory enhancing material. The shell has an outer surface rendered hydrophobic by hydrophobic groups covalently bond to the outer surface of the shell. The shell may be rendered hydrophobic by reacting hydroxyl groups at outer surface of the shell with fatty acid halides to covalently attach fatty acid moieties to the surface of the capsule.
