The invention relates to a process and apparatus to cool harvest grapes, the grapes being transported from a harvest reception vessel (1) to a press (5) or to a maceration vessel (23), characterized in that the grapes are charged with carbon dioxide during transport to the press (5) and/or during transport to the maceration vessel (23). As a result a flavor improvement of the wine is achieved.

The invention claimed is: 1. An apparatus for producing wine, comprising: a harvest reception vessel; a press coupled to the harvest reception vessel via a first connection line, wherein a first quantity of grapes from the harvest reception vessel is transported to the press via the first connection line; a maceration vessel coupled to the harvest reception vessel via a second connection line, wherein a second quantity of grapes from the harvest reception vessel is transported to the maceration vessel via the second connection line; and a controller, wherein the controller controls a supply of a gaseous carbon dioxide and a supply of a liquid carbon dioxide to the first and second connection lines and wherein the controller interrupts the supply of the carbon dioxide if a temperature of the grapes falls below 7° C.; wherein the controller controls the supply of the gaseous carbon dioxide and the supply of the liquid carbon dioxide to the first and second connection lines by varying a position of a first valve associated with the gaseous carbon dioxide and a second valve associated with the liquid carbon dioxide. 2. The apparatus for producing wine of claim 1, further comprising one or more temperature measuring devices. 3. The apparatus for producing wine of claim 1, wherein the varying of the position of the first valve associated with the gaseous carbon dioxide and the second valve associated with the liquid carbon dioxide varies a temperature of the first and/or second connection lines. 4. The apparatus for producing wine of claim 1, wherein when the position of the first valve associated with the gaseous carbon dioxide is open and the position of the second valve associated with the liquid carbon dioxide is closed, a highest temperature is reached. 5. The apparatus for producing wine of claim 1, wherein when the position of the first valve associated with the gaseous carbon dioxide is closed and the position of the second valve associated with the liquid carbon dioxide is open, a coldest temperature is reached. 6. The apparatus for producing wine of claim 1, wherein when a process of the supply of the gaseous carbon dioxide and the supply of the liquid carbon dioxide is started, the position of the first valve associated with the gaseous carbon dioxide is open and the position of the second valve associated with the liquid carbon dioxide is closed. 7. The apparatus for producing wine of claim 1, wherein the supply of the gaseous carbon dioxide and the supply of the liquid carbon dioxide to the first and second connection lines is controlled by a third valve associated with the first connection line and a fourth valve associated with the second connection line. 8. A process to cool harvest grapes comprising the steps of transporting the grapes to a press via a first connection line or to a maceration vessel via a second connection line, controlling a supply of a gaseous carbon dioxide and a supply of a liquid carbon dioxide to the first and second connection lines by a controller, and detecting the temperature of the grapes, wherein the supply of carbon dioxide is interrupted if the temperature of the grapes falls below 7° C. and further comprising a macerating step which lasts only a few hours; wherein the controller controls the supply of the gaseous carbon dioxide and the supply of the liquid carbon dioxide to the first and second connection lines by varying a position of a first valve associated with the gaseous carbon dioxide and a second valve associated with the liquid carbon dioxide. 9. The process of claim 8, wherein the varying of the position of the first valve associated with the gaseous carbon dioxide and the second valve associated with the liquid carbon dioxide varies a temperature of the first and/or second connection lines. 10. The process of claim 8, wherein when the position of the first valve associated with the gaseous carbon dioxide is open and the position of the second valve associated with the liquid carbon dioxide is closed, a highest temperature is reached. 11. The process of claim 8, wherein when the position of the first valve associated with the gaseous carbon dioxide is closed and the position of the second valve associated with the liquid carbon dioxide is open, a coldest temperature is reached. 12. The process of claim 8, wherein when a process of the supply of the gaseous carbon dioxide and the supply of the liquid carbon dioxide is started, the position of the first valve associated with the gaseous carbon dioxide is open and the position of the second valve associated with the liquid carbon dioxide is closed. 13. The process of claim 8, wherein the supply of the gaseous carbon dioxide and the supply of the liquid carbon dioxide to the first and second connection lines is controlled by a third valve associated with the first connection line and a fourth valve associated with the second connection line.
