La viticulture durable: concept et application aux terroirs viticoles

Abstract

Evoquer la notion de durabilité pour la vigne, plante multimillénaire, et le vin, tous deux intimement liés aux origines de notre civilisation, peut paraître un non-sens. Le vin revêt en effet une dimension culturelle, voire cultuelle intemporelle, qui recouvre tout à la fois les sciences, les savoir-faire ancestraux, la sociologie, les religions. Notre filière a en effet imprimé une marque indélébile, une symbolique immortelle, dans l’évolution du monde.
Le développement durable traduit fidèlement l’esprit d’un type de développement, formalisé par le rapport Brundtland, à l’origine du concept :

un développement qui répond aux besoins du présent, sans compromettre la capacité des générations futures de répondre aux leurs.
La préservation de l’environnement et plus globalement la Viticulture Durable, s’intègrent progressivement dans la plupart des itinéraires techniques viticoles et oenologiques. A partir des années 90, une vision durable associant notamment les impacts locaux et planétaires ont été développés au sein de l’Organisation Internationale de la Vigne et du Vin, (Résolution OIV CST 1/2004 www.oiv.int) :
« Approche globale à l’échelle des systèmes de production et de transformation des raisins, associant à la fois la pérennité économique des structures et des territoires, l’obtention de produits de qualité, la prise en compte des exigences d’une viticulture de précision, des risques liés à l’environnement, à la sécurité des produits et la santé des consommateurs et la valorisation des aspects patrimoniaux, historiques, culturels, écologiques et paysagers ».

Flavonol and anthocyanin potential of Spanish minority grapes and its relationship with wine colour

Global climate change is currently affecting vine phenology and causing a decoupling between technological and phenolic maturity of the grapes [1]. Wine industry has to face the challenge of making quality wines from grapes with an unbalanced phenolic composition.

Vitivoltaics: overview of the impacts on grapevine performance, wine quality, design features and stakeholder perceptions

This multidisciplinary study investigates “”Vitivoltaics,”” where photovoltaic (PV) panels are integrated into vineyard systems to generate renewable energy while providing partial shade to grapevines.

DOES LIGNIN AN ACCEPTABLE MARKER OF GRAPESEED MATURATION AND QUALITY?

Usually the winemaker consider polyphenols from the grape berry as an actor of the wine quality. There are frequently consider as a marker of grape maturity. It is commonly known that winemaker consider tannins and anthocyanins as main polyphenol actors for winemaking practices and wine quality. Here we will focus on the characterisation of lignins in grape seeds. Previous studies suggest that the seed is lignified [1], which could explain the change in colour of the seed when it reaches maturity and thus provide a reliable indicator for describing the maturity stage in the seed.

Drought effect on aromatic and phenolic potential of seven recovered grapevine varieties in Castilla-La Mancha region (Spain)

The effects of climate change are seriously affecting the quality of wine grapes. High temperatures and drought cause imbalances in the chemical composition of grapes. The result is overripe grapes with low acidity and high sugar content, which produce wines with excessive alcohol content, lacking in freshness and not very aromatic. As a consequence, the search of varieties with capacity of produce quality grapes in adverse climate conditions is a good alternative to preserve the sustainability of vineyards. In this work, quality parameters of seven Vitis vinifera L. cultivars (five whites and two reds) recently recovered from extinction and grown under two different hydric regimes (rainfed and irrigated) were analyzed during the 2020 vintage. At harvest time, weight of 100 berries, must physicochemical parameters (brix degree, total acidity, malic acid, pH), and carbon and oxygen isotope ratios (δ13C, δ18O) were determined. Subsequently, varietal aroma potential index (IPAv) and total polyphenol index (TPI) were analyzed. Quality parameters, IPAv and TPI, showed significant differences between varieties and water regimes. Both red varieties, Moribel and Tinto Fragoso, stood out for their high aromatic and phenolic potential, which was higher under rainfed regime. Regarding to white varieties, Montonera del Casar and Jarrosuelto stood out in terms of varietal aroma potential. Montonera del Casar high acidity in its musts and Jarrosuelto showed the highest berry weights.
