Vacuum tapping means (10) are sealingly connected to the upper portion (4A) of the vessel (4) and maintain a pressure therein which is between a first predetermined value P1 lower than the atmospheric pressure and a predetermined value P2 lower than P1, and liquid tapping means (20) are sealingly connected to the lower portion (4B) of the vessel and pump liquid from said lower portion up to an area for pouring into a glass. The vacuum tapping means includes a vacuum source (11) for lowering the pressure in the upper portion (4A) of the vessel (4) to P1 and vacuum partial-compensation means (14) adapted for feeding a gaseous fluid into the upper portion of the vessel when the pressure in said upper portion is lower than P2. ## Claims ### Claim at position 1 -14. (canceled) ### Claim 15 An apparatus for pouring into a glass a liquid, in particular wine, contained in a container, including: a vacuum tapping means, adapted to be sealingly connected to the upper portion of the container and to maintain, in said upper portion, a pressure between first and second predetermined values, respectively below the atmospheric pressure and below the first predetermined value, and a liquid tapping means, adapted to be sealingly connected to the lower portion of the container and to pump liquid from said lower portion to a pouring zone to the glass, wherein said vacuum tapping means comprises: a vacuum source, adapted to lower the pressure in the upper portion of the container to the first predetermined value, and a partial vacuum compensation means, adapted to make a gaseous fluid enter the upper portion of the container when the pressure in the upper portion is below the second predetermined value. ### Claim 16 (depends on 15) The apparatus according to claim 15, wherein the vacuum source includes a vacuum pump associated with a pressure switch for controlling said vacuum pump, adapted to actuate the vacuum pump when the pressure in the upper portion of the container is above the first predetermined value. ### Claim 17 (depends on 15) The apparatus according to claim 15, wherein the partial vacuum compensating means includes a valve tared to the second predetermined value. ### Claim 18 (depends on 15) The apparatus according claim 15, wherein the partial vacuum compensating means is connected to the open air so as to cause outside air to enter the upper portion of the container. ### Claim 19 (depends on 15) The apparatus according to claim 15, wherein the partial vacuum compensating means are connected to a dedicated gas source so as to make gas enter said source in the upper portion of the container. ### Claim 20 (depends on 19) The apparatus according to claim 19, wherein said dedicated gas source is chosen amongst a neutral gas source and a carbon dioxide source. ### Claim 21 (depends on 15) The apparatus according to claim 15, wherein the liquid tapping means comprises a self-priming liquid pump. ### Claim 22 (depends on 21) The apparatus according to claim 21, wherein the liquid pump is peristaltic and reversible. ### Claim 23 (depends on 21) The apparatus according to claim 21, wherein the liquid tapping means also comprises, at the pouring zone to the glass, a pour spout connected to the outlet of the liquid pump. ### Claim 24 (depends on 23) The apparatus according to claim 23, wherein the pour spout is connected to the outlet of the liquid pump via a flexible tubing. ### Claim 25 (depends on 23) The apparatus according to claim 23, wherein the pour spout incorporates a venting means. ### Claim 26 (depends on 23) The apparatus according to claim 23, wherein the pour spout incorporates an actuator for controlling the liquid pump. ### Claim 27 (depends on 21) The apparatus according to claim 21, wherein the liquid tapping means also comprises a liquid flow sensor, placed in series with the liquid pump. ### Claim 28 (depends on 21) The apparatus according to claims 21, wherein the liquid tapping means also comprises a connecting conduit for connecting the bottom of the container with the inlet of the liquid pump, said connecting conduit including both a first portion, adapted to be introduced inside the container so as to extend between the bottom and the upper end neck of the container, and a second portion adapted to extend outside the container between the first portion and the inlet of the liquid pump, said first and second portions are designed to be removably connected to each other. ### Claim 29 (depends on 28) The apparatus according to claim 28, wherein the first and second portions are designed to be connected to each other by bearing pressing the second portion against the first portion when said first portion rests on the neck of the container. ### Claim 30 (depends on 28) The apparatus according to claim 28, wherein the first and second portions are designed to be connected to each other by fastening one on the other.
