1. An apparatus for roasting coffee beans, the apparatus comprising:
a vessel configured to contain coffee beans,
an electrical heating device configured to heat the coffee beans contained in the vessel,
at least one temperature sensor configured to measure a temperature in the vessel,
a control system operable to control the electrical heating device,
wherein the control system is configured to:
apply a roasting recipe dedicated to roasting partially pre-roasted beans according to a temperature versus time profile by controlling at least the electrical heating device based on the temperature measured by the at least one temperature sensor,
detect a decrease of a consumption of electrical power of the electrical heating device in function of time, and
stop heating if no decrease of the consumption of electrical power is detected after a set reference time t1.
