Bio‐metaethics viticulture proposed by the Giesco. Direct charter with producers. Example of evaluation of training systems

The global wine market is polarising over brands versus origin. Provenance is emerging as a marketing megatrend in many fast moving consumer goods. Origin has always been important in wine but does that mean consumers understand, or care about terroir?

Le but de ce travail est de faire une synthèse des résultats de plusieurs années de recherche en Italie centrale, sur les caractéristiques fonctionnelles du sol pour la production de vin de qualité. Le cépage de référence est le Sangiovese

Aim: The aim of this report is to present evidence on the potential of Greek and Cypriot grape varieties to serve as a sustainable solution to mitigate climate change.

Methods and Results: The work provides a review of recent works involving Greek and Cypriot varieties’ performance under high temperatures and increased dryness.

In this video recording of the IVES science meeting 2025, Marie Le Scanff (University of Bordeaux, UMR 1366 Oenologie, Institut des Sciences de la Vigne et du Vin, Villenave d’Ornon, France) speaks about the sensory contribution of grape stems during winemaking and about the role of astilbin, a sweet polyphenol. This presentation is based on an original article accessible for free on OENO One and on a technical article published on IVES Technical Reviews.

Nitrogen (N2) is critical in grape berries, especially in organic wine making. After intake, N2 follows various metabolic and allocation routes and, from veraison, partly reallocates into berries. Water deficit affects the N2 nutrition due to a poor diffusion in soil solution and vascular mobilisation. Also, affects photosynthesis and the energy needed for metabolism, whose extent would depend on the stomatal sensitivity of the plant. We have assessed the effect of a moderate water deficit from pea size, in 3 years old field grown potted plants of Chardonnay (CH) and Cabernet Sauvignon (CS), differing in stomatal sensitivity, on the N2 status of plant parts. Water deficit reduced photosynthesis, leaf area and fresh and dry plant mass along the season, but up to a higher extent in CS.
