A beverage dispenser capable of supplying a supercooled beverage without being influenced by a type of raw water. In various embodiments, the beverage dispenser includes a raw water treatment device that deaerates or filters raw water, a primary cooling device that cools the raw water to an ice point or so, and a secondary cooling device that cools the raw water into a supercooled state. In certain embodiments, the beverage dispenser further includes an anti-freezing liquid tank, a refrigerant circuit that cools the anti-freezing liquid to a supercooling temperature, and a brine circuit that circulates the anti-freezing liquid. According to certain aspects of the embodiments, a supercooled beverage can be quickly and reliably phase-changed to a different state when discharged to the outside.
