A beverage maker includes: a container; a fermentation tank; a beverage dispenser including a lever configured to control dispensing of the beverage and a limit switch configured to be turned on and off based on manipulation of the lever; a beverage dispensing channel that connects the container and the beverage dispenser and that guides the beverage; a beverage dispensing valve disposed in the beverage dispensing channel; a pressure sensor that measures gas pressure inside the container; and a controller. The controller detects whether the limit switch is turned on, opens the beverage dispensing valve to dispense the beverage accommodated in the container through the beverage dispenser based on detecting that the limit switch is turned on, determines a gas pressure value corresponding to the gas pressure inside the container measured by the pressure sensor, and determines a dispensed amount of beverage based on the gas pressure value.
