Beverage maker and method for making beverage

A beverage maker apparatus comprising:

• a fermentation tank having a space formed therein in which a beverage is made;
• a temperature sensor configured to detect a temperature of the fermentation tank;
• a temperature controller configured to control the temperature of the fermentation tank;
• a gas discharger configured to control a pressure within the fermentation tank, wherein the gas discharger comprises:
• a gas pressure sensor configured to measure the pressure within the fermentation tank, and
• a gas discharge valve configured to open and close a gas discharge channel connected to the fermentation tank;
• and
• a controller configured to control a fermentation process when yeast is added to the beverage that is being made in the fermentation tank, the fermentation process comprising:
• a pre-fermentation process of controlling the temperature controller on the basis of a first set temperature, and a main-fermentation process of controlling the temperature controller on the basis of a second set temperature,
• wherein the pre-fermentation process includes a process for activating yeast added to the fermentation container,
• wherein the fermentation process includes a process in which alcohol and carbonic acid are formed by the activated yeast, and
• wherein the controller is further configured to close the gas discharge valve and control the gas discharge valve based on a degree of activation of the yeast,
• wherein the gas discharger further comprises:
• a safety valve connected to the gas discharge channel,
• a pressure release valve connected to the gas discharge channel, and
• a noise reducing device mounted on the pressure release valve.
