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 pressure regulator may control a pressure of gas introduced into the container, and a lance used to pierce a pressurized gas cylinder may include a leading face arranged to reliably pierce a cylinder closure. The regulator may include valve features to reduce valve chatter or hammering and provide a more reliable pressure seal.

1. A piercing lance for piercing pressurized gas cylinders, comprising: a body having a front piercing end, a rear end opposite the front piercing end, and a fluid passageway extending between the front piercing end and the rear end, the front piercing end including a tapered portion having an opening at a distal end of the tapered portion and a longitudinal axis, the tapered portion having a first surface partially defining the opening at the distal end that is arranged in a plane perpendicular to the longitudinal axis and a second surface partially defining the opening at the distal end that is arranged in a plane transverse and not perpendicular to the longitudinal axis. 2. The lance of claim 1, wherein the second surface is arranged in a plane that is at an angle of 55-70 degrees to the longitudinal axis. 3. The lance of claim 1, wherein the second surface is arranged in a plane that is at an angle of 55-60 degrees to the longitudinal axis. 4. The lance of claim 1, wherein the tapered portion has an outer surface arranged at an angle of 10-30 degrees to the longitudinal axis. 5. The lance of claim 1, wherein an outer surface of the tapered portion includes a vent channel that extends from the first or second surface to a proximal end of the tapered portion. 6. The lance of claim 1, wherein the fluid passageway extends along the longitudinal axis. 7. The lance of claim 1, wherein the body includes a gasket-contacting portion proximal of the tapered portion that is arranged to contact a gasket positioned between the lance and a gas cylinder and create a gas-tight seal between the gasket and the lance. 8. The lance of claim 7, wherein the gasket-contacting portion includes an annular surface arranged in a plane perpendicular to the longitudinal axis. 9. The lance of claim 7, wherein the gasket-contacting portion includes a cylindrical surface that extends around the longitudinal axis. 10. The lance of claim 1, wherein the opening has a size of about 1-3 mm. 11. The lance of claim 1, wherein a line extending along an area where the first and second surfaces meet passes through the opening. 12. The lance of claim 1, wherein a line extending along an area where the first and second surfaces meet passes through a center of the opening. 13. The lance of claim 1, wherein the tapered portion has a surface finish with an average roughness of about 16 micro-inches. 14. The lance of claim 1, wherein the tapered portion includes a vent channel that extends from the second surface to a proximal end of the tapered portion. 15. The lance of claim 14, wherein the vent channel extends radially outwardly from the proximal end of the tapered portion. 16. A piercing lance for piercing pressurized gas cylinders, comprising: a body having a front piercing end, a rear end opposite the front piercing end, and a fluid passageway extending between the front piercing end and the rear end, the front piercing end including a tapered portion having an opening at a distal end of the tapered portion and a longitudinal axis, the tapered portion having a first and second surfaces defining the opening at the distal end, the first and second surfaces each being arranged in respective first and second planes that are at an angle of 20-35 degrees relative to each other.
