A serving apparatus without oxygen, from an open bottle, of a liquid that can be affected by oxygen, in particular wine, by insufflating inert pressurized gas in said bottle, comprising a fixed engagement member (1) and a releasable fastening member (2) fixed to a bottle (30). A pressurized gas supply without oxygen is provided, for example nitrogen or argon, having for example a cylinder (41) connected to a gas supply machine (40). By the gas supply machine (40) the pressurized gas can be distributed and supplied in the bottles (30), flowing through a pressure reducing valve (42), a pressure switch (43) for indication of the lack of gas in the cylinder (41), a solenoid valve (44) adapted to delivery gas on driving the pressure switch (47), a safety valve (45) adapted to avoid that a maximum threshold value is exceeded, a gas tank (46) that prevents a solenoid valve (44) from opening continuously, a pressure switch (47) adapted to keep the pressure in the bottle (30) fixed. |
