Abstract: A vaporisation device (2) comprising a pressure chamber (4), a controller (6), and a pressure sensor (22) for measuring an internal pressure within the pressure chamber, wherein: the pressure chamber comprises a reservoir of volatile material (30), a heater (14) electrically coupled to the controller and a choked flow outlet (12) for allowing vapour (32) to exit the pressure chamber under choked flow conditions; and, the controller is configured to control the heater in dependence on the measured internal pressure to cause vaporisation the volatile material for the internal pressure to be sufficiently high that, in use, vapour exiting the pressure chamber through the choked flow outlet does so under choked flow conditions.

Abstract: Black leaf tea that has the appearance of orthodox processed black tea but has the infusion characteristics of CTC processed black leaf tea. Various methods are given to define orthodox appearance and CTC infusion character.

Abstract: A process for manufacturing black leaf tea that looks and feels like orthodox processed tea but has the liquor characteristics of a fuller fermented CTC processed tea. The process involves withering a first supply of freshly plucked tea leaves, macerating the withered leaves, allowing the macerated withered leaves to ferment to produce macerated dhool, withering a second supply of freshly plucked tea leaves, mixing the macerated dhool obtained from the first supply of leaves with the withered leaves obtained from the second supply of leaves, rolling the mixture, allowing the rolled mixture to ferment, and drying the fermented mixture to yield black leaf tea.
