The first and second aerosol generating portions contain an aerosol generating agent, and respectively first and second flavourant(s) which are different from each other. At least one of the first and second aerosol generating portion is a foam containing non-tobacco flavourant. The foam is configured to produce aerosol upon heating. The foam is not meltable under conditions of aerosol generation at a temperature comprised within a heating temperature range of the aerosol generating device. The heating temperature range is between 180° C. and 350° C. The foam includes a foam-forming agent selected from the group consisting of agar, gellan gum, lecithin, polyglycerol esters of fatty acids, glycerol esters of fatty acids, sorbitan esters of fatty acids, and/or mixtures thereof. ## Claims ### Claim 1 An aerosol generating substrate for a non-combustion aerosol generating device comprising: a first aerosol generating portion and at least one
