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

This study reports results concerning the comparison of conventional, organic and biodynamic farming in a Pinot blanc and Rhine Riesling vineyard in Northern Italy.

Young white wines should be consumed within a short time after bottling to avoid loss of their fresh, fruity attributes. Shelf-life of white wines can be extended if they are stored under suitable conditions of time and temperature prior to consumption.

Ten years have passed since the enactment and implementation of law no. 26,870 “national drink wine” in Argentina, a pioneering legislation worldwide that seeks to disseminate the cultural characteristics inherent in the production, elaboration, and consumption of wine, as well as its deep-rooted traditions.

3-Mercaptohexanol (3MH) is a volatile thiol occurring in several white and red wines, where it can contribute to fruity attributes. Its content is typically high in wines from certain grape varieties, in particular Sauvignon blanc, where it is considered a varietal marker. The strong nucleophilic character of thiols makes 3MH rather unstable during wine storage, due to the presence of several strong electrophilic species. Among these electrophilics, those arising from the oxidation of flavan3-ols such as catechin and epi-catechin have been indicated as critical for 3MH stability. Accordingly, there is a generalized interest towards the ability of vinification practices to reduce 3MH loss during aging through the management of wine flavan-3-ols content.

The term “terroir”, originated in France, comprises the interaction of soil, climate, and topography with the vines of a specific variety and may be extended to the human impact due to the active choice of viticultural and oenological treatments.
