To provide a beverage dispenser capable of appropriately and smoothly supplying a supercooled beverage. According to the present invention, there is disclosed a beverage dispenser including a beverage supply circuit 7 which supplies a carbonated beverage to the outside a primary cooling device 13, a secondary cooling device 30, and a heat exchanger 16 for supercooling which allows these components to cool the carbonated beverage flowing through the beverage supply circuit 7 into a supercooled state at a temperature of a solidifying point or less. The heat exchanger 16 supplies the carbonated beverage in the supercooled state to release the supercooled state in the outside, and the carbonated beverage on standby for serving in a portion of the beverage supply circuit 7 cooled by at least the heat exchanger 16 for supercooling is maintained in an unsaturated state.
