Claim 0:
1. A beverage maker, comprising:
a fermentation tank including a space in which a beverage is made;
a refrigerant cycle device configured to cool the fermentation tank, the refrigerant cycle device comprising:
an evaporator wound around a portion of an external surface of the fermentation tank, wherein the evaporator is disposed to contact an outer surface of the fermentation tank; and
a compressor configured to supply a refrigerant to the evaporator;

a heater disposed below the fermentation tank, the heater installed to contact a bottom surface of the fermentation tank;
a temperature sensor configured to detect a temperature of the fermentation tank, the temperature sensor disposed on the external surface of the fermentation tank and spaced apart from the evaporator; and
a controller configured to drive the compressor to decrease the temperature in the fermentation tank which accommodates a mixture including water and wort to a fermentation temperature while the beverage is being made, to supply yeast into the fermentation tank in response to determining that the temperature detected by the temperature sensor reaches a reference temperature, to stop driving of the compressor in response to determining that the temperature detected by the temperature sensor reaches a first step temperature of a plurality of step temperatures, which is higher than the fermentation temperature, and to re-drive the compressor after a predetermined period of time has elapsed, wherein the reference temperature is higher than the first step temperature, wherein the controller drives the compressor in response to determining that the temperature detected by the temperature sensor is higher than the first step temperature by a reference value or greater for the predetermined period of time.
