Data deluge: Opportunities, challenges, and lessons of big data in a multidisciplinary project

Phenolic compounds or polyphenols are the most abundant and ubiquitous secondary metabolites present in the plant kingdom with more than 8000 phenolic structures currently known. These compounds play an important role in plant growth and reproduction, providing protection against biotic and abiotic stress such as pathogen and insect attack, UV radiation and wounding. (poly)phenols are widely distributed in the human diet mainly in plant-derived food and beverages (fruits, vegetables, nuts, seeds, herbs, spices, tea and red wine).

Flowers and berries abscission (coulure) can lead, during some vintages and for sensitive cultivars, to dramatic yield losses with detrimental impacts on the wine industry. Many exogenous and endogenous factors are known to favor defaults in reproductive development and coulure, among which extreme temperatures and carbon imbalances play a major role.

The Campanha Gaúcha is located in the pampa biome and has unique characteristics, as it is the hottest producing region with the lowest volume of rain in Southern Brazil. Furthermore, the large extensions of flat or low-sloping areas, harsh winters and great sunshine during the ripening period, made this the second largest producer of fine wines in Brazil.

In viticoltura, la comprensione dell’influenza della temperatura dell’aria sulla dinamica della maturazione assume importante rilievo in relazione all’ ottimizzazione dell’ epoca di raccolta da cui dipende in modo significativo la qualità del prodotto finale.

Winemaking is a complex microbial process involving the co-existence and interactions of various microorganisms [1].
