Delineation significance in viticultural zoning: examples in the Southern Côtes-du-Rhône


In order for a spatialized gestion of wine-producing areas, delineation of viticultural zones is needed. Viticultural zoning according to qualitative expression of varieties is a great concern for the wine professionals in the Southern Côtes-du­Rhône (lat. 43°50′-44°30′ North, long. 4°30′-5°10’East of Greenwich meridian). In this study, viticultural terroirs are regarded as parts of agricultural land, where harvest expression is likely to be homogeneous. Geographic information analysis, based on soil landscape characterization, is aimed at terroir spatial distribution modelling. Geographic data available are : field observations ; aerial photographs ; topographic, geological, and soil maps; Digital Elevation Model; satellite images. Terroir determination separately considers two objects: the soil landscape unit and the viticultural plot; both are described by about twenty environmental variables; 3 additional variables describe plots only. Multivariate clustering obtained from several classifications calculated on these variables, determines terroirs at two different scale and resolution levels: «global», from 55 soil landscape units; «local», from 91 plots. The terroirs interpolated from plot clusters are characterized by black Grenache harvest data measured over the course of 17 vintages (1982-1998): their harvest composition differ. Such locally defined terroirs are compared with the globally defined terroirs. Validity of global viticultural terroirs is discussed, in relation to variables influence and plot localization relevance.

Hydroxytyrosol (HT) is a phenolic compound present in olives, virgin olive oil and wine. HT has attracted great scientific interest due to its biological activities which have been related with the ortho-dihydroxy conformation in the aromatic ring. In white and red wines, HT has been detected at concentrations ranging from 0.28 to 9.6 mg/L and its occurrence has been closely related with yeast metabolism of aromatic amino acids by Ehrlich pathway during alcoholic fermentation. One of the most promising properties of this compound is the neuroprotective activity against pathological mechanisms related with neurode-generative disorders including Alzheimer’s and Parkinson’s disease.

Prosensorial potential of new fungi-resistant varieties in modern oenology

The introduction into the Italian wine supply chain of the latest generation of fungi-resistant grapevine varieties, endowed with a greater or lesser strong resistance to downy and powdery mildews, represents a valid tool of making viticulture more sustainable, particularly in northern regions of the peninsula, where climatic conditions accentuate the pressure of fungal diseases. However, the affirmation of resistant varieties is a function of their agronomic value, as well as of their oenological and sensorial value. The purpose of this study was to evaluate in detail the sensory potential of the new resistant varieties, in order to understand their real possibility of inclusion in the modern global enological context.

Effect of plant fining agents in the must flotation process. Functional characterization

Flotation is one of the most used processes for clarifying white grape must after the pressing process. To date, gelatine is the more used fining agent, its action being improved when combined with bentonite and silica sol.

Enological evaluation of the attitude of the grapevine fumin to give varietal wines

Initiatives have been ongoing in recent years to safeguard biodiversity in the oenological sector via a process of enhancement of ancient varieties, under a pressure of a market strongly oriented towards production deriving from native vines of specific geographical zones. In that sense, Aosta Valley
(Italy) has raised the need to preserve and characterize its minority vine varieties which have the potentiality to give varietal wines. Fumin represents the 7% of the production of the region with 16 hectares of vineyards and 753 hectolitres of derived wine. Due to its large phenolic potential, strong astringency and deep colour, it has long been, and is still today, assembled or blended with other varieties as occurs, for example, for the Torrette.
