Enological, economical, social and viticulture ”terroir” units as fundamental elements of mosaic of “big” zoning

Abstract

[English version below]

Nous savons tous très bien qu’on a assisté au cours de ces dix dernières années à une éclosion soudaine de recherches sur le zonage viti-vinicole qui, à partir par exemple du modèle du concept de “terroir”, se sont de plus en plus enrichies en passant aux “Unités ou Systèmes de Transformation” (UTTE) et “Valorisation” (UTCE) pour terminer avec les “Systèmes productifs globaux du Territoire” (UTB) comprenant en filière les aspects existentiels (UTBES), sociaux (UTBSO) et économiques (UTBEC) hypothisés dans le “GRANDE ZONAZIONE: Grand zonage” (MORLAT R., 1996, CARBONNEAU A., 1996, TOUZARD J.M. 1998, CARBONNEAU A., CARGNELLO G., 1996, 1998, CARGNELLO G., 1994, 1995, 1996, 1998, 1999, 2001, -MILOTIC A., CARGNELLO G., PERSURIC G., 1999, PERSURIC G., STAYER M., CARGNELLO G., 2000, MILOTIC A., OPLANIC M., CARGNELLO G., PERSURIC G., 2000).

Nous sommes donc arrivés à supposer que pour zoner en viticulture, et non pas seulement en viticulture, il faut partir des considérations : existentielles, sociales, économiques qui représentent les différents échelons des grands objectifs du zonage, en se servant pour les rejoindre des moyens placés en filière suivants : “terroir” vignoble (exemple : variété, clones, écartement, systèmes de conduite, gestion de la végétation, de la production et de la vendange, etc.), cave ( exemple : utilisation des appareillages, technologies et techniques d’innovation, etc.), communication, marketing, etc., comme on l’a prévu dans le “GRAND ZONAGE” (CARGNELLO G., 1996). Pour vérifier la validité de cette “nouvelle” organisation du zonage viti-vinicole, nous avons conduit en Istrie (Croatie) pour une durée de 5 ans des recherches pour établir si le zonage devait descendre uniquement des aspects concernant le “terroir” ou s’il devait descendre des aspects qui partent de considérations d’ordre social et économique et ensuite de celles “techniques” comprenant la cave, le vignoble, le terrain et le climat. Les recherches conduites en Istrie (Croatie) sur les objectifs et sur les moyens cités ci-dessus ont démontré ultérieurement la validité de ce moyen de procéder dans le zonage viti-vinicole. Elles ont démontré par ailleurs que l’incidence du “terroir” à un niveau décisionnel dans le zonage viti-vinicole peut s’amenuiser par rapport aux autres composantes et en être même dépassée, c’est-à-dire que l’on a justement décidé dans certains cas de faire un vignoble dans un terroir non adapté à la viticulture car les “Unités de Culture Viticole, de Transformation, de Valorisation” et les systèmes productifs globaux ont eu une importance fondamentale pour le zonage. Ces recherches seront exposées dans cette communication.

In the any last decade was the large number of research about viticulture zoning. The begin of zoning research was funded on the term and principle of “terroir”. Then, the term “terroir” was divided to “unite de terroir de base”, “unité de système de culture viticole”, “unite o sisteme de transformation e valorizazion” and as the last new segment “sistemi produtivi globali del territorio” (the global productive system of territory). All this new terms, with a respect to social and economical aspects has a unique name of ”.big” zoning (GRANDE ZONAZIONE) (MORLAT R. 1996, CARBONNEAU A., 1996, TOUZARD J.M., CARBONNEAU A., CARGNELLO G., 1998, CARGNELLO G., 1994, 1995, 1996, 1998, 1999, 2001, MILOTIC A., CARGNELLO G., PERSURIC G. 1999, PERSURIC G., STAVER M., CARGNELLO G., 2000, MILOTIC A, OPLANIC M., CARGNELLO G., PERSURIC G., 2000).

According quoted annotation for successfully process of viticulture zoning, and not only to viticulture, need to start of next items : existence, social aspects, economic aspects, which present the different stairs in the zoning process. The sequence of next terms, “terroir” – vineyards (for example: variety, clone, training form, canopy management, yield and other) – vine cellar (for example : technology of wine making) – communication – marketing make a important factors to process of “big” zoning.For confirm the quoted “new” hypothesis in the zoning process was done the research in the Istria (Croatia). For needs of research was taken all social and economical aspects and then the different techniques in vine growing and wine making, and the characteristics of soil am climate.The research made in Istria was confirmed the hypothesis of “big” zoning process. This research was confirmed also the importance of “terroir” and in the same moment the importance of lower units “unite de culture viticole de transformation de valorisation” for viticulture production.

Effect of vineyard management strategy on the nutritional status of irrigated « Tempranillo » vineyards grown in semi-arid areas

The combination of cover crops with regulated deficit irrigation has been lately shown to be a good method to improve harvest quality in irrigated vineyards of Southern Europe with semiarid climate, as an alternative to the conventional management, that consists on mechanical tillage and irrigation from fruitset to veraison and from then on reduced, or even ended.

VINIoT – Precision viticulture service

The project VINIoT pursues the creation of a new technological vineyard monitoring service, which will allow companies in the wine sector in the SUDOE space to monitor plantations in real time and remotely at various levels of precision. The system is based on spectral images and an IoT architecture that allows assessing parameters of interest viticulture and the collection of data at a precise scale (level of grape, plant, plot or vineyard) will be designed. In France, three subjects were specifically developed: evaluation of maturity, of water stress, and detection of flavescence dorée. For the evaluation of maturity, it has been decided first to work at the berry scale in the laboratory, then at the bunch scale and finally in the vineyard. The acquisition of the spectral hyperstal image as well as the reference analyzes to measure the maturity, were carried out in the laboratory after harvesting the berries in a maturity monitoring context. This work focuses on a case study to predict sugar content of three different grape varieties: Syrah, Fer Servadou and Mauzac. A robust method called Roboost-PLSR, developed in the framework of this work (Courand et al., 2022), to improve prediction model performance was applied on spectra after the acquirement of hyperspectral images. Regarding the evaluation of water stress, to work with a significant variability in terms of water status, it has been worked first with potted plants under 2 different water regimes. The facilities have allowed the supervision of irrigation and micro-climatic conditions. The regression models on agronomic variables (stomatal conductance, water potential, …) are studied. To detect flavescence dorée, the experimental plan has consisted of work at leaf scale in the laboratory first, and then in the field. To detect the disease from hyper-spectral imaging, a combination of multivariate curve resolution-alternating least squares (MCR-ALS) and factorial discriminant analysis (FDA) was proposed. This strategy proved the potential towards the discrimination of healthy and infected leaves by flavescence dorée based on the use of hyperspectral images (Mas Garcia et al., 2021).

Tools for assessing vine nitrogen status; role of nitrogen uptake in the “terroir” effect

Among the numerous nutrients vines extract from the soil, nitrogen is the one that interferes most with vine vigor, yield, berry constitution and wine quality. Many studies relate on the influence of various levels of nitrogen

ACCUMULATION OF GRAPE METABOLITES IS DIFFERENTLY IMPACTED BY WATER DEFICIT AT THE BERRY AND PLANT LEVELS IN NEW FUNGUS DISEASE-TOLERANT GENOTYPES

The use of new fungus disease-tolerant varieties is a promising long-term solution to better manage chemical input in viticulture, but unfortunately little is known regarding these new hybrids fruit development and metabolites accumulation in front of abiotic stresses such as water deficit (WD). Thus, prior to the adoption of such varieties by the wine industry in Mediterranean regions, there is a need to consider their suitability to WD.

Influence of phenolic composition and antioxidant properties on the ageing potential of Syrah red wines measured by accelerated ageing tests.

Red wine ageing impacts its chemical and sensory characteristics such as colour, astringency and aromas evolution. Wine ageing involves many chemicals and physico-chemical reactions. Oxygen has an important role in these evolutions, especially during bottle ageing. It is known that wine composition and its antioxidant capacity are correlated to its ability to undergo with oxygen exposure [1]. A high oxygen exposure can affect wine quality by the formation of undesirable oxidative volatile compounds such as acetaldehyde [2]. Thus, ageing capacity is an important factor for wine quality and is related to extent of oxidation with ageing [3].
