A liquid dispensing device including a dispense head configured to be placed and secured onto a bottle of liquid in a manner which enables the liquid to be dispensed. The dispense head includes a stopper having gas inlets and a liquid intake tube. A gas intake and a dispense spout are also mounted on the dispense head. A valve assembly allows pressurized gas to be introduced into the dispense head and into the bottle of liquid such that selective channeling of gas or liquid can be controlled to flow through the dispense spout thus enabling either liquid to pour through the spout or gas to clear the spout. A system utilizing this dispense head and a method of dispensing liquid using this head are possible with this device.

What is claimed is: 1. A method comprising: placing a dispensing head into a neck of a bottle, said dispensing head having a pour spout a rotating valve and a gas intake; moving said bottle with inserted dispensing head into contact with a dispensing machine, such that the intake on said dispensing head is in fluid communication with a gas line on said dispensing machine; receiving, at said dispensing machine, information relating to an amount of liquid to be dispensed; and injecting from the dispensing machine into the bottle an amount of an inert gas sufficient to displace the amount of liquid to be dispensed through the pour spout, by rotating the rotating valve such that said gas intake has a gas pathway into the bottle and inert gas. 2. The method of claim 1, further including electrically sensing when said dispensing head is in contact with said dispensing machine and injecting into the bottle an amount of inert gas only when electrically sensing said dispense head is in contact with said dispensing machine. 3. The method of claim 1, further including a final step of clearing liquid from said pour spout with a puff of said inert gas. 4. The method of claim 1, further including a step after moving the bottle into contact with a dispensing machine but before injecting into the bottle an inert gas a step of purging air from said bottle, wherein said dispensing head prevents back flow of air into said bottle and replacing purged air in said bottle with an inert gas. 5. The method of claim 4, wherein said purging step requires rotating the rotary valve on said dispensing head. 6. The method of claim 1, further comprising a final step of removing the bottle from the dispensing machine, wherein said dispensing head is retained on the bottle and prevents air from entering the bottle. 7. The method of claim 1, wherein moving said bottle into contact with a dispensing machine includes placing said bottle in a temperature controlled stall in said dispensing machine. 8. The method of claim 1, wherein receiving at said dispensing machine, information relating to an amount of liquid to be dispensed includes having a user select a pour volume at a displayed price. 9. The method of claim 1, wherein prior to receiving at said dispensing machine, information relating to an amount of liquid to be dispense, a step of receiving at said dispensing machine a payment amount.
