Devices and methods for extracting a beverage from a container (700), such as a wine bottle. Beverage can be extracted from a container (700) by inserting a needle (200) through a container closure (730), such as a cork, delivering pressurized gas into the container (700) via the needle, and dispensing beverage from the container via the needle. A pressure regulator (600) may control a pressure of gas introduced into the container (700), and a lance (25) used to pierce a pressurized gas cylinder (100) may include a leading face arranged to reliably pierce a cylinder closure. The regulator (600) may include valve features to reduce valve chatter or hammering and provide a more reliable pressure seal. |
