Linde Gas España highlights carbonic snow for improved cold maceration of grapes
The ENOFRESH system enables grape must to be cooled quickly and evenly using liquid CO₂, supporting the extraction of aromatic compounds and polyphenols during the early stages of winemaking
Managing grape temperature from the beginning of the winemaking process is an important factor in preserving the fruit's characteristics and oenological potential. In this context, Linde Gas España highlights the benefits of cold maceration, a technique that helps extract compounds responsible for wine colour, aroma and structure.
To achieve this, liquid CO₂ is converted into carbonic snow, which rapidly lowers the temperature of the grape mash and distributes the cooling effect evenly. The process also helps protect the raw material against oxidation.
ENOFRESH, a solution for precise temperature control
Through its ENOFRESH system, Linde offers wineries a solution for accurately controlling temperature during this stage of production. The company also supplies other gases used in winemaking, such as nitrogen and sulphur dioxide, which can be applied in different processing and preservation operations.
According to the company’s LinkedIn post, temperature control using carbonic snow supports greater polyphenol extraction and helps preserve the expression of the grapes in the resulting wine.
In this way, the use of gases during the early stages of winemaking makes it possible to control parameters that influence the final quality of the product, even before it reaches the barrel.
