Le zonage viticole en Italie. État actuel et perspectives futures

Abstract

Over the past few decades, viticultural research has made numerous contributions which have made it possible to better understand the behavior of the vine as well as its response to the conditions imposed on it by the environment and agronomic practices. However, these results have only rarely been used in the practical management of vineyards because the research has been carried out using partial experimental models where reality is only represented by a few factors which are sometimes even made more complex by the introduction of elements foreign to the existing situation and difficult to apply to production (varieties, methods of cultivation, management techniques, etc.). To these reasons, one could add a low popularization of the results obtained, as well as the difficulty of implementing scientific contributions, which does not allow the different production systems to fully express their potential. This limit of viticultural research can only be exceeded by the design of integrated projects designed directly on and for the territory. Indeed, only the integrated evaluation of a viticultural agro-system, which can be achieved through zoning, makes it possible to measure, or even attribute to each element of the system, the weight it exerts on the quality of the wine.

The purpose of zoning is, in fact, to produce information whose practical application in the short and long term is simple and possible. With this in mind, we can therefore recommend different levels of zoning which are the subject of studies of variable territorial extent (Fregoni, 1995) thus relying on different research methods (Falcetti, 1994).

The first possible level that can be defined of micro-zoning concerns the size of the farm (estate). This zoning should provide support for choosing the most effective business management techniques for each situation (choice of plant material, development of fertilization plans, identification of management techniques, etc.). This level of zoning, because it is carried out within the limits of an estate, does not have many repercussions on the territory. A survey carried out at this level does not necessarily require institutional skills (research institutes, local authorities, etc.) but it is exhausted within the framework of a private technical advice service (consulting).

We could call meso-zoning, on the other hand, the work that studies productive-administrative realities such as an appellation of origin. In this case, the zoning concerns a territory whose area is not very large (of the order of a few hundred or thousands of hectares) and can therefore use very detailed and effective analysis methods. Another advantage of meso-zoning is to refer to a well-defined interlocutor whose goal is to favor the development of a territory and all its products and not of a single farm. The zoning carried out on the scale of the vineyard of a cooperative cellar, quite frequent in the Italian wine panorama, falls into this category. These caves, the last level is that of macro-zoning, the aim of which is to study a broader geographical context, from the scale of a region to the community dimension (Riou, 1994). The practical repercussions of these zonings are not easy to identify because they are rather intended to study certain phenomena in a very general way, such as the distribution of a territory into a few homogeneous zones from a climatic point of view, or the comparison between the behavior of a few grape varieties in very different environments. What is lacking in the application of the results of such research is the detailed consideration of the variability of the territory which is very important in determining the oenological results of each region.

la caratterizzazione dell’areale viticolo “terre alte di brisighella”: aspetti metodologici e primi risultati

La zonazione viticola rappresenta un importante strumento di indagine per valutare e interpretare le potenzialità produttive e qualitative di un territorio. Con l’obiettivo di studiare come l’ambiente influisca sulla qualità dell’uva nell’areale di Brisighella, sono stati monitorati, nelle annate 2007, 2008 e 2009, 14 vigneti per la varietà Albana e 38 per la varietà Sangiovese, rappresentativi di una area vitata di circa 1000 ha.

Development of a new method to understand headspace aroma distribution and explore the pre-sensory level in perceptive interactions involved in red wine fruity aroma expression

A part, at least, of red wines fruity expression may be explained by perceptive interactions involving particularly various substituted ethyl esters and acetates present at concentration far below their olfactory threshold, specifically thanks to synergistic effects. Wine sensory perception is directly linked to the stimulation of the taster at the level of olfactory epithelium by volatiles. These compounds are liberated from the matrix to the atmosphere, and will then be smelt. From a physico-chemical point of view, these volatiles ability to be released may be evaluated by their partition coefficients, which correspond to the volatile concentration ratio between the liquid and gas phase. Our goal is, through these coefficients determination, to assess if volatile matrix composition is able to impact the volatility of some compounds, and then explain sensory perception, i.eto evaluate what is called the pre-sensorial level impact.

The effect of terroir zoning on pomological, chemical and aromatic composition of Muscat d’Alexandrie grapevine variety cultivated in Tunisia

La composition du raisin de la variété Muscat d’Alexandrie a été étudiée dans trois terroirs différents au Nord-Est de la Tunisie (RafRaf, Baddar et Kelibia).
Des échantillons de raisins ont été récoltés à maturité industrielle durant les saisons 2001 et 2002 dans les trois régions citées. Les paramètres pomologiques (poids moyen de la grappe et de la baie) et physico-chimiques

Identification of arbuscular mycorrhizal fungi species preferentially associated with grapevine roots inoculated with commercial bioinoculants 

Arbuscular mycorrhizal fungi (AMF) form symbiotic associations with plant roots and can help plants acquire nutrients from the soil in exchange for photosynthetic carbon. Commercial bioinoculants containing AMF are widely available and represent a potential opportunity to reduce the dependence of grapevines on agrochemicals. However, which commercially available AMF species colonize vine roots and affect vine growth remains unknown. The aim of this study was to identify the AMF species from commercial bioinoculants that colonize grapevine roots using high-throughput sequencing, and to evaluate the performance of five commercial bioinoculants and their effects on own-rooted Cabernet sauvignon.

Toward a model of grape proanthocyanidin extraction during vinification

PAs are compartmentalised within the grape berry, and differ in their composition and degree of extractability. Within each compartment, the CWM limits PA extraction firstly by its degree of permeability and secondly its ability to complex with PA molecules.
