1. An aerosol-generating device, comprising:
a first storage portion;
a first liquid aerosol-forming substrate contained within the first storage portion;
an electrospray device configured to generate a first aerosol from the first liquid aerosol-forming substrate, the electrospray device comprising:
a nozzle configured to receive the first liquid aerosol-forming substrate from the first storage portion, and
a voltage circuit comprising a circuit ground, the voltage circuit being configured to apply a voltage difference between the first liquid aerosol-forming substrate and the circuit ground;
a second storage portion;
a second liquid aerosol-forming substrate contained within the second storage portion;
a heater configured to heat second liquid aerosol-forming substrate from the second storage portion; and
a mixing chamber in fluid communication with the nozzle and the heater,
wherein the heater is downstream of the nozzle.
