Aerosol-generating system with liquid aerosol-forming substrate identification

An aerosol-generating system comprising:

• a liquid storage portion configured to hold a liquid aerosol-forming substrate, the storage portion in contact with a wick;
• a first electrode;
• a second electrode spaced from the first electrode, at least a portion of the liquid storage portion being arranged between the first electrode and the second electrode, the portion of the liquid storage portion arranged between the first electrode and the second electrode contains the liquid aerosol-forming substrate when the liquid aerosol-forming substrate is held in the storage portion, the first electrode being arranged to circumscribe an entirety of a surface of the liquid storage portion at a first point, and the second electrode being arranged to circumscribe the entirety of the surface of the liquid storage portion at a second point, the first point and the second point are longitudinally spaced apart;
• and
• a control system configured to measure an electrical quantity of the liquid aerosol-forming substrate held within the liquid storage portion between the first electrode and the second electrode, and, in response to the measured electrical quantity of the liquid aerosol-forming substrate being within a range of reference of a plurality of range of references, identify the liquid aerosol-forming substrate held in the storage portion as corresponding to an approved producer.
