A beverage-making apparatus comprising:

• a fermentation tank that has an opening and that defines a space therein;
• a beverage ingredient pack configured to be selectively accommodated in the space of the fermentation tank through the opening;
• a fermentation tank cover configured to, based on the beverage ingredient pack being accommodated in the space of the fermentation tank, close the opening of the fermentation tank;
• a supplier located outside the fermentation tank and configured to supply an additive;
• a water supply flow path that is located outside the fermentation tank and that is connected to the supplier;
• a main flow path that connects the supplier to the beverage ingredient pack;
• a main valve installed in the main flow path;
• a beverage extraction path branched from the main flow path;
• an air pump configured to supply air in a space between an inside wall of the fermentation tank and an outside surface of the beverage ingredient pack;
• a refrigerant tube wound around an outer surface of the fermentation tank;
• and
• a heat insulating wall that surrounds the fermentation tank and the refrigerant tube,
• wherein the beverage extraction path has a first connecting part that is connected to the main flow path,
• wherein the main flow path has a second connecting part that is connected to the beverage ingredient pack,
• wherein the main valve is provided between the first connecting part and the second connecting part, and
• wherein the main valve is opened based on a liquid being extracted from the beverage ingredient pack.
