Apparatus and method for producing fermented liquor

A method for producing fermented liquor using a fermented liquor producing device, including:

• a main body, including:
• a control board, including:
• a memory storing at least one instruction, at least one processor, a storage, a thermostat, and a communication interface, and including a carbon dioxide container connection, a container, including:
• an outer container, including:
• a fermented liquor discharge valve, a fermented liquor discharge port, a foreign body discharge valve, and a foreign body discharge port, and a container cap for sealing the container, and including:
• a gas discharge port, a gas supply port, a pressure gauge hole, a pressure gauge, and a thermometer, the method comprising:
• closing the gas discharge port based on a pressure in the container reaching a first pressure;
• measuring a first time for the pressure in the container measured through the pressure gauge to become a second pressure, and storing the first time in the storage;
• opening the gas discharge port;
• closing the gas discharge port based on the pressure measured through the pressure gauge becoming the first pressure and measuring a second time for the pressure in the container measured through the pressure gauge to become the second pressure;
• and
• repeatedly performing, based on the second time being smaller than the first time:
• the opening the gas discharge port;
• the closing the gas discharge port based on the pressure measured through the pressure gauge becoming the first pressure;
• and
• the measuring the second time for the pressure in the container measured through the pressure gauge to become the second pressure.
