Apparatus and methods are described for use with a vaporizer that vaporizes at least one active ingredient of a plant material. In response to receiving a first input to the vaporizer, the plant material is heated, in a first heating step. An indication of the temperature of the plant material is detected, and, in response to detecting an indication that the temperature of the plant material is at a first temperature, the first heating step is terminated, by withholding causing further temperature increase of the plant material. The first temperature is less than 95 percent of the vaporization temperature of the active ingredient. Subsequently, a second input is received at the vaporizer. In response thereto, the plant material is heated to the vaporization temperature, in a second heating step. Other applications are also described.

An aerosol-generating device includes a heating chamber structure, a heater coupled to the heating chamber structure, and a compression assembly. The heating chamber structure defines a fixed-volume enclosure and is configured to hold an aerosol-forming substrate within a first region of the enclosure. The heater is proximate to a first surface that at least partly defines the first region and is configured to generate heat that is transmitted into the first region to cause the aerosol-forming substrate to form an aerosol without any combustion. The compression assembly includes a compression plate and a compression actuator. The compression plate and the first surface define opposing boundaries of the first region. The compression actuator moves the compression plate through the enclosure to adjustably compress the aerosol-forming substrate in the first region against the first surface.
