Abstract
Devices and methods are disclosed for extracting fluids from within a container sealed by a cork or septum without removal of the cork or septum or the contamination of the fluid within the container by reactive gases or liquids. Embodiments of the device can include a needle connected to a valve which is in turn connected to a source of pressurized gas for displacing the fluid. Further embodiments of the device can comprise additional components that act to force the needle to be inserted through the cork or septum along a linear path, to aid in preventing buckling of the needle, to clamp the device to the container, to prevent expulsion of the cork or septum from the container, and to guide the needle through a specified region of the cork or septum. Various valves, pressure regulators, pressure ranges, needle geometries, gas selections are also presented. This device is particularly suited for the dispensing and preservation of wine.
