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

Climate change substantially challenges winegrowing regions, threatening terroir stability through heatwaves, altered precipitation patterns, and increased drought frequency.

Grapevine is one of the most important crops worldwide. In a climate change scenario, vineyards face not only abiotic challenges, but also recurrent annual outbreaks of diseases, such as downy mildew and grey mould, caused by the oomycete Plasmopara viticola (PV) and the fungi Botrytis cinerea (BC), respectively.

Depending on the variety, grapes contain several chemical classes of aromatic compounds (i.e., terpenols, norisoprenoids, benzenoids) mainly stored as glycosides in berry skin.

In Chile there is a dry farming area known as a traditional wine region, where varieties brought by the Spanish conquerors still persist. These varieties, in general, are cultivated under traditional systems, with low use of technical and economic resources, and low profitability for their grapes and wines. In this region, as in other wine grape growing areas, climatic conditions have changed significantly in recent decades. In particular, the occurrence of spring frosts, when bud break has already begun, have generated significant losses for these growers.
