Abstract: The present invention relates to a process and device for incorporating a dose of liqueur in a bottle of champagnized wine, wherein the device comprises a receptacle containing the liqueur which receptacle is connected to a pump from which the delivery is introduced near the bottom of the bottle. A tank under pressure containing champagne is connected to the interior of the bottle by a pipe provided with a valve. Another pipe with radial hole at the chosen fill level for the bottle emerges from the bottle and terminates in the tank. A conduit enables the bottle to be maintained at the same pressure as that prevailing in the tank. Via a channel in the head, the bottle may be placed under excess pressure to evacuate the surplus of wine via the pipe. The invention is particularly applicable to oenology.
