Devices and methods for extracting a beverage from a container, such as a wine bottle. Beverage can be extracted from a container by inserting a needle through a container closure, such as a cork, delivering pressurized gas into the container via the needle, and dispensing beverage from the container via the needle. A single valve can control flow of gas into the container, flow of beverage from the container, and stop all flow.

1. A beverage extraction device, comprising: a base for supporting components of the beverage extraction device;a body mounted to the base;at least one needle having at least one lumen extending from a proximal end to a distal end, the proximal end of the needle being mounted to the body, the at least one needle being arranged to be inserted through a closure at an opening of a beverage container with movement of the body relative to the closure;a gas source mounted to the body, fluidly coupled to the needle and arranged to deliver pressurized gas to the at least one lumen at the proximal end of the at least one needle; anda valve fluidly coupled to the gas source and the at least one needle, the valve having a control portion movable along a linear path between three flow states including a gas flow state in which the valve permits gas flow from the gas source to the at least one needle and prevents flow of beverage out of the container via the at least one needle, a beverage flow state in which the valve prevents gas flow from the gas source to the at least one needle and permits flow of beverage out of the container via the at least one needle, and an off state in which the valve prevents gas flow from the gas source to the at least one needle and prevents flow of beverage out of the container via the at least one needle, the valve including a spring that biases the control portion to move to the beverage flow state, and wherein the control portion is movable linearly against a bias of the spring from the beverage flow state, to the off state, and then to the gas on state. 2. The device of claim 1, further comprising a lever movably mounted to the body and movable to move the control portion between the three flow states. 3. The device of claim 1, further comprising a beverage outlet in fluid communication with the at least one needle such that the valve is operable to control flow between the at least one needle and the beverage outlet. 4. The device of claim 1, further comprising: a pair of clamp arms mounted to the base and movable relative to each other to clamp a beverage container neck and support the base on the beverage container. 5. The device of claim 1, wherein the body is movably mounted to the base such that movement of the body relative to the base moves the needle relative to the base. 6. The device of claim 1, wherein the gas source includes a compressed gas cylinder and a regulator to regulate a pressure of gas provided to the at least one needle. 7. The device of claim 1, wherein the at least one needle is arranged for insertion through a cork of a wine bottle and for delivery of gas into the wine bottle. 8. The device of claim 1, wherein the at least one needle is arranged for insertion through a cork of a wine bottle and for delivery of wine from the bottle. 9. The device of claim 1, wherein the at least one needle includes a single needle arranged for insertion through a cork of a wine bottle, for delivery of gas into the wine bottle, and for delivery of wine from the bottle. 10. The device of claim 1, wherein the valve includes a valve body with a stepped inner surface and the control portion includes a spool with a plurality of seals arranged to interact with the stepped inner surface of the valve body to control flow through the valve. 11. The device of claim 10, wherein the stepped inner surface includes a first section having a first diameter, a third section having a third diameter, and a second section between the first and third sections and having a second diameter, the first diameter being larger than the second and third diameters, and the second diameter being larger than the third diameter. 12. The device of claim 11, wherein the spool includes first, second and third seal elements arranged to contact and form a seal with each of the first, second and third sections, respectively. 13. The device of claim 12, further comprising a gas port in fluid communication with the first section and the gas source, and a needle port in fluid communication with the second section and the at least one needle. 14. The device of claim 13, wherein the second seal element controls flow between the gas port and the needle port. 15. A method for extracting wine from a wine bottle, comprising: inserting at least one needle through a closure at an opening of a beverage container;moving a valve control portion along a linear path against a spring bias from a wine flow state to an off state and then to a gas flow state in which the valve permits flow of gas from a pressurized gas source through the at least one needle and into the wine bottle;moving the valve control portion along the linear path from the gas flow state to the off state and then to the wine flow state in which flow of gas through the at least one needle is stopped and wine flows from the bottle, through the at least one needle and to a beverage outlet; andmoving the valve control portion along the linear path to the off state in which flow of gas through the at least one needle is stopped and flow of wine from the bottle through the at least one needle is stopped. 16. The method of claim 15, wherein the steps of operating the valve include positioning a lever of a beverage extraction device at a position that corresponds to the respective valve state. 17. The method of claim 16, further comprising: releasing the lever to allow the lever to move under the spring bias to the wine flow state.
