Abstract
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.
