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 single valve can control flow of gas into the container, flow of beverage from the container, and stop all flow.
