Device for incorporating a dose of liqueur in a bottle of champagnized wine

A device for injecting a dose of liqueur into a bottle containing a liquid saturated with a gas, and for correcting the height of the liquid to a chosen level while maintaining the gas saturation of the liquid comprising:

• (a) a gas-pressurized closed tank containing saturated liquid;
• (b) a head operative to seal against the bottle above said chosen level;
• (c) first pipe means connected from the tank through the head into the interior of the bottle and having first valve means operative to open the pipe means for selectively introducing liquid from the tank into the bottle;
• (d) dose injection means including an injection tube extending through the head and having an open free end positioned to be located substantially at the bottom of the bottle;
• (e) means for pressurizing the interior of said bottle to a pressure in excess of the pressure of the saturating gas in the bottle;
• (f) means for delivering excess liquid from above the chosen level in the bottle into said closed tank when the interior of the bottle is pressurized at said excess pressure;
• and
• (g) means for selectively eliminating said excess pressure in the bottle.
