Patent ID: 8490832

Claim:
A wine extraction device for the extraction of wine from within a bottle sealed by a cork, comprising: a needle having an inlet and an outlet and wherein the needle is adapted to penetrate through the cork such that the outlet is passed through the cork and positioned within the bottle with the inlet positioned outside of the bottle; a pressurized source of gas; a pressure regulator having a regulator inlet fluidly connected to the pressurized source and a regulator outlet, the pressure regulator operable to reduce a pressure of gas provided from the pressurized source to a lower pressure at the regulator outlet, the lower pressure selected to cause flow of wine out of the bottle through the needle while preventing an expulsion of the cork from the bottle; and a valve having a first valve inlet fluidly connected to the pressure regulator outlet and a first valve outlet fluidly connected to the needle inlet, the valve being arranged to control gas flow from the pressure regulator outlet to the needle inlet such that gas is controllably delivered into the bottle through the needle, wherein the needle is arranged to penetrate through the cork to deliver gas into the bottle and conduct wine out of the bottle, and such that upon removal of the needle from the cork, the cork reseals to prevent passage of fluid and gas through the cork.
