Provided is a liquid supply system with which it is possible to perform quality control of a liquid provided by the system. A liquid supply system (101) that pumps a liquid in a storage container (10) through a supply tube (30) and dispenses the liquid from a liquid dispensing spout of a dispensing device (50), said liquid supply system (101) comprising: a jetting prevention device (110) that has a liquid inlet (111), a liquid outlet (112), and a float (116) for closing the liquid outlet due to inflow of air from the liquid inlet, thereby preventing jetting of pressurized air from the liquid dispensing spout, and provides cleaning or no cleaning inside of a conduit in the liquid supply system; a liquid absence detection device (120) that has a no-liquid/liquid passing sensor (122) for detecting that the liquid in the storage container is gone, and sends empty storage container information; and a transmission device (130) that has a control unit (131) for carrying out control of information transmission to a communication line (200).

The inventive system and method advantageously enable superior preserved storage and selective dispensation of liquids by storing wine (or other liquids) in a pressurized environment to ensure that the stored liquid does not come into contact with air, and then by selectively dispensing a portion of the stored liquid, in accordance with a desired dispensing regime, by utilizing a controlled source of pressure force to apply a sufficient pressure to the pressurized environment to expel the desired volume of the liquid in a pressurized stream directed to a dispensing/pouring interface through a conduit or equivalent delivery system. In at least several novel embodiments thereof, the system and method of the present invention are configured for use with wine-in-bag (“WinB”) products.
