There is provided a receptacle for use with an apparatus for generating an inhalable medium, the receptacle including a chamber for containing a flavour material, whereby, in use, at least one of a vapour and an aerosol generated by the apparatus can flow through the flavour material to entrain one or more constituents from the flavour material to produce the inhalable medium. The receptacle is configured to maintain an air gap separation between an outlet end of the chamber and flavour material when it is received in the chamber, the outlet end being configured to enable the inhalable medium to flow out of the chamber.
