A carbonated beverage storage device is provided to reduce the amount of storage gas by respectively controlling a gas-exhaust valve and a gas supply valve based on different pressures. A carbonated beverage storage device(101) comprises a storage tank(110), an inlet/outlet port(120), a gas pipe(130), a gas supply valve(140), a gas-exhaust valve(145) and a controller(150). The storage tank stores a carbonated beverage. The inlet/outlet port accepts and discharges the carbonated beverage inside and outside. The gas pipe accepts and discharges storage gas inside and outside. The gas supply valve supplies the storage gas to the gas pipe. The gas-exhaust valve ejects the storage gas from the gas pipe. The controller controls the opening and closing of the gas supply valve and the gas-exhaust valve. The gas supply valve is opened at the pressure lower than the base pressure of the inside of the storage tank. |
