Landscape qualities and keys for action

Abstract

Parallèlement à la connaissance des aptitudes viticoles, le terroir témoigne d’une identité locale, d’une spécificité des conditions de productions et d’une originalité des lieux. Le paysage, support sensible des choix d’aménagements locaux, constitue une entrée pertinente pour une réflexion durable, car il permet d’identifier et de conforter les supports identitaires, de redonner une vision spatiale à un projet technique viticole et de l’intégrer dans les échelles multiples d’un territoire. Une démarche de paysage s’appuie sur un besoin local, exprimé par une collectivité ou des viticulteurs. Elle se décompose en une première étape de lecture et de diagnostic de paysage permettant de se questionner sur la place, le rôle et l’image du viticulteur dans le territoire. Cette première étape révèle la qualité des projets viticoles et recherche la cohérence entre les différents gestionnaires du territoire. Mais les observations et interrogations formulées ne restent qu’une entrée, à compléter par l’expertise de personnes ressources locales ou par des enquêtes auprès des différents acteurs territoriaux. Ensuite intervient l’élaboration du projet, associé à un plan de gestion, qui répond à un dysfonctionnement ou besoin viticole local, tels les aménagements des abords de cave, des sentiers pédagogiques et la réimplantation de haies. Les viticulteurs, principaux gestionnaires d’un terroir viticole, doivent être au cœur des discussions et force de proposition quant à l’avenir de leur territoire et aux priorités du projet. La pré-existance d’un mouvement collectif et d’une conscience environnementale au sein des viticulteurs et des acteurs locaux est un atout non négligeable pour favoriser les dialogues et les dynamiques d’un projet. Par ces démarches, le paysage devient l’expression d’un projet viticole, concerté, voulu, approprié et non subi ; c’est-à-dire une clé d’action pour la viticulture durable.

δ13C : A still underused indicator in precision viticulture  

The first demonstration of the interest of carbon isotope composition of sugars in grapevine, as an integrated indicator of vineyard water status, dates back to 2000 (Gaudillère et al., 1999; Van Leeuwen et al., 2001). Thanks to the isotopic discrimination of Carbon that takes place during plant photosynthesis, under hydric stress conditions, it is possible to accurately estimate the photosynthetic activity. Ever since, δ13C has been widely applied with success to zonation, terroir studies and vine physiology research, but is still not widely used by viticulturists. This is quite astonishing by considering the impact of global warming on viticulture and the need to improve water management, that would justify a widespread use of δ13C. The lack of private laboratories proposing the analysis, the cost of the technology, as well as the long analytical delays, have been detrimental to its development. Some laboratories tried to overcome the analytical difficulties of isotopic analysis by using fourier transformed infrared spectroscopy, as a fast and cheap alternative to the official OIV method (IRMS). These claimed FTIR models have never been published or peer reviewed and cannot be considered robust. In this work, thanks to the recent acquisition of IRMS technology, new modern and robust applications of δ13C for viticulture are proposed. This includes the use of the analysis to make parcel separations at harvesting, the possibility to increase the precision of hydric stress cartography and the potential cost reduction when compared with Scholander pressure bomb analysis.

Antioxidant activity of yeast peptides released during fermentation and autolysis in model conditions

Aging wine on lees benefits different wine sensory and technological properties including an enhanced resistance to oxidation. Several molecules released by yeast, such as membrane sterols and glutathione, have been previously proposed as key factors for this activity [1].

Untargeted metabolomics reveals the impact of cork oxygen transfer on non-volatile compounds during red wine ageing

During red wine aging, numerous chemical reactions occur, contributing to the modification and enhancement of the wine sensory parameters over time [1].

A new approach for sensory characterization of grape. Relationship with chemical composition

Characterize taste and mouthfeel properties of grapes elicited by the phenolic fraction (PF) of grape berries and establish relationships with chemical variables. METHODS: As many as 31 diverse grape lots of Tempranillo Tinto and Garnacha Tinta from three different regions were harvested. Grapes were destemmed and macerated in 15% of ethanol for one week and extracts were submitted to solid phase extraction. The recovered polyphenolic fraction was reconstituted in wine model and characterized by a panel of 21 wine experts employing a list of 23 taste and mouthfeel-related attributes following a rate-k-attributes methodology. RESULTS: Six significant attributes among the 31 samples differed based on ANOVA results: “dry”, “coarse”, “bitter”, “dry on tongue”, “sticky” and “watery”. PCA with VARIMAX algorithm was calculated.

Wine shaking during transportation: influence on the analytical and sensory parameters of wine

According to OIV reports, annual world wine consumption fluctuated around 240-245 mln hL over the past decade. The general market globalization has led to the situation when almost half of the consumed wine is exported to other countries. Of this volume, more than 60 mln hL are bottled still and sparkling wines.
