This read-write INTEGER identifies the pot's brew method: automatic-drip, percolator, french-press, or espresso. An admin sets or reads this to know, or if the hardware allows, configure, which brewing technique the device uses, which affects expected brew times and temperature behavior. For example, setting potType to espresso(4) would tell any monitoring logic to expect the shorter, higher-pressure brew cycle typical of espresso machines rather than a slow drip cycle.
