Abstract
A method of making coffee is provided. After a cold-brewed coffee is extracted from coffee beans, nitrogen gas is charged into the cold-brewed coffee. The cold-brewed coffee into which nitrogen gas is dissolved, is cooled to form a nitrogen-charged coffee. Therefore, the nitrogen-charged coffee may keep a rich density of foam and a flavor.

An apparatus of making coffee comprising:
- a keg storing a cold-brewed coffee;
- a nitrogen tank containing nitrogen gas, the nitrogen tank being connected with keg by a first line to be configured to provide nitrogen gas with the keg to form a nitrogen-charged coffee;
- a discharging unit being connected with the keg by a second line to be configured to discharge the nitrogen-charged coffee;
- a first cooling unit covering the second line to be configured to cool the nitrogen-charged coffee;
- and
- a third line connecting the nitrogen tank with the discharge unit;
- wherein the discharging unit is configured to selectively open/close the second line and the third line to selectively discharge the nitrogen-charged coffee or to discharge the nitrogen-charged coffee and nitrogen gas at the same time.
