Abstract

There is provided a flavour system for use in a tobacco industry product. The flavour system comprises lyophilised botanical material, an activator capable of releasing flavourant from the lyophilised botanical material through contact of the activator with the lyophilised botanical material, and a removable barrier preventing contact between the lyophilised botanical material and the activator. The barrier is removable to permit the activator to contact the lyophilised botanical material, thereby to cause release of the flavourant.
