THE CENIT PROJECT DEMETER STUDY THE TREND OF GAP BETWEEN THE MATURITY OF SUGAR CONTENT AND THAT OF POLYPHENOLS.

Twenty-six Spanish wine companies seek to overcome changes in grape ripening resulting from the effects of climate change. In recent years, Winegrowers and winemakers confirm the difficulties they face in determining the optimal harvest point.

 

Under the title Development of Viticultural and Oenological Strategies and Methods in the face of climate change. Application of new Technologies that improve the Efficiency of the Resulting processes (Demeter), The project that analyzes the consequences of climate change is framed.

The first results of the project, in which they will be invested 27 million euros, will be obtained in the year 2011. As stated in the project Demeter, Among the most significant changes at the viticultural level caused by global warming is, in addition to the different ripening of the grapes, decreased productivity or changes in diseases and pests.

As a consequence, different musts and wines will be obtained, less balanced. To achieve aroma and mature polyphenols, musts with a high sugar concentration must be fermented., which leads to excessively alcoholic wines with low acidity.

This type of broth is heavy and more vulnerable to oxidation phenomena., while if you choose to process earlier harvests you will obtain fresher and lighter wines., but greener and less aromatic complexity. The project addresses the study of viticultural adaptation to this new scenario.

And the consequences of climate change are beginning to take their toll..
