Devices and methods for guiding a needle in movement through a bottle closure, such as a cork, to extract fluids from the bottle without removal of the cork. A needle may be attached to a device body by a needle base, which includes a surface arranged to engage with a needle guide to guide movement of the needle base and needle relative to the guide. A needle guide may also provide a shield for the needle tip and/or a needle opening.

1. A beverage extraction device, comprising: a base for supporting components of the beverage extraction device;a needle having at least one lumen extending from a proximal end to a distal end, the needle being movably mounted to the base and arranged to be inserted through a closure at an opening of a beverage container;a needle base at the proximal end of the needle and having an engagement surface; anda needle guide attached to the base and having an opening to guide the needle in movement relative to the base, the needle guide including an engagement surface arranged to contact the engagement surface of the needle base and guide movement of the needle base and needle relative to the needle guide,wherein the needle guide includes a protrusion that includes the engagement surface of the needle guide, and the needle base includes a hole that includes the engagement surface of the needle base and is arranged to engage with the protrusion. 2. The device of claim 1, wherein the engagement surface of the needle guide includes a conically shaped hole, and the engagement surface of the needle base includes a conically shaped member arranged to fit into the conically shaped hole. 3. The device of claim 1, wherein the needle guide includes a through hole arranged to receive the needle. 4. The device of claim 1, wherein the protrusion includes a conically shaped member with a size and shape that is complementary to the hole of the needle base. 5. The device of claim 1, wherein the needle guide is fixed relative to the base. 6. The device of claim 1, further comprising a gas source fluidly coupled to the needle and arranged to deliver pressurized gas to the at least one lumen at the proximal end of the needle. 7. The device of claim 6, wherein the gas source includes a compressed gas cylinder. 8. The device of claim 1, wherein the needle and needle base are attached to a rail, and the base includes a channel arranged to receive and guide movement of the rail relative to the base. 9. The device of claim 8, comprising a body that includes the rail, and the needle base and needle are attached to the body. 10. The device of claim 1, comprising a body that is movable relative to the base, and wherein the needle base is threadedly engaged with the body such that the needle base and needle are removable from the body. 11. The device of claim 1, wherein the needle is arranged for insertion through a cork of a wine bottle and for delivery of a gas into the wine bottle. 12. The device of claim 1, wherein the needle is arranged for insertion through a cork of a wine bottle and for delivery of wine from the bottle. 13. The device of claim 1, wherein the needle has an opening near the distal end of the needle, the needle guide includes a through hole arranged to receive and guide the needle, and the through hole is shaped to direct any liquid expelled from the needle opening away from the proximal end of the needle. 14. A method for extracting a beverage from a container, comprising: inserting a needle through a closure of a container by moving the needle toward a needle guide, the closure sealing an opening of the container closed prior to needle insertion such that a beverage in the container is prevented from passing through the opening;engaging a surface of a hole in a needle base positioned near a proximal end of the needle with a surface of a protrusion of the needle guide received into the hole to guide movement of the needle relative to the needle guide, the surface of the hole in the needle base being positioned around a radially outer side of the needle; andextracting a beverage from the container via the needle while the needle is inserted through the closure. 15. The method of claim 14, wherein the closure includes a material capable of resealing upon withdrawal of the needle from the closure. 16. The method of claim 14, wherein the step of engaging a surface includes engaging a conically shaped outer surface of the needle base with a conically shaped surface of the needle guide. 17. The method of claim 14, wherein the needle guide includes a through hole that receives the needle and guides the needle in motion relative to the needle guide. 18. The method of claim 14, wherein the step of extracting includes introducing gas into the container through the closure via the needle. 19. The method of claim 14, wherein the step of extracting includes flowing beverage from the container and through the closure via the needle. 20. The method of claim 14, comprising: withdrawing the needle from the closure and positioning the needle in a fully withdrawn position such that a needle opening at a distal end of the needle is shielded by the needle guide. 21. A needle assembly for use with a beverage extraction device, comprising: a needle having at least one lumen extending from a proximal end to a distal end, the needle being arranged to be inserted through a closure at an opening of a beverage container; anda needle base at the proximal end of the needle and having a needle bore in which the proximal end of the needle is positioned, the needle base having a guide hole in communication with the needle bore and including an engagement surface arranged to receive and engage with a complimentary engagement surface of a protrusion on a needle guide of a beverage extraction device and guide movement of the needle base and needle relative to the needle guide,wherein the needle extends through and from the guide hole of the needle base such that the distal end of the needle is positioned outside of the guide hole. 22. The needle assembly of claim 21, wherein the guide hole is located at a distal end of the needle base and has a conical shape with a wider portion of the conical guide hole positioned distally of a narrower portion of the conical guide hole. 23. The needle assembly of claim 21, further comprising a needle hub attached at a proximal end of the needle and received in the needle bore. 24. The needle assembly of claim 21, wherein the needle base includes a thread arranged to engage with a beverage extraction device to secure the needle assembly to the beverage extraction device. 25. The needle assembly of claim 21, wherein a distal portion of the needle bore is arranged to closely fit around the needle and support the needle. 26. The needle assembly of claim 25, wherein a distal end of the needle bore includes a flared portion arranged so the needle bore is wider at the distal end than at more proximal portions of the needle bore. 27. The needle assembly of claim 21, wherein the needle base is formed of a plastic material.
