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

Abstract

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.

Ceramic imprint in wine: influence of hydraulic ratio on ceramic dissolution and wine pH in amphorae systems

This interaction is primarily due to an acidic attack on the ceramic by the wine. It results in (1) the dissolution of the ceramic into the wine and the release of a wide variety of elements; and (2) an increase of the wine pH. The extent of these effects depends on the mineralogical and chemical composition of the ceramic, as well as the hydraulic ratio of the ceramic-wine system (the term hydraulic ratio (ρ) defines here the volume of wine over the surface area of the ceramic in contact with the wine).

Terroir in Tasting: A sensory approach for marketing fine Australian wines of provenance as memorable experiences

Aims: Establishing an image of fine wine through the Geographical Indication (GI) system is of interest to the Australian wine sector. Beyond provenance, the sensory experience of fine wine is often linked to consumption with appropriate foods. For this purpose, studies were undertaken to understand consumer perceptions of what

The vineyard of the future: producing more with less  

similar to other agricultural producers, grape growers face increasing pressure to improve productivity and production efficiency while reducing their environmental impact. Threats due to extreme climate events, as well as the uncertainty of available water and labor, provide significant challenges to the future of grape production. This presentation will provide an integrated overview of the tools and technologies being developed to address these issues and to help growers manage vineyards in the future, including vineyard design, remote and proximal sensing, automation, data management and decision support systems, and germplsm improvement. The potential impact of these advancements on vineyard productivity, fruit quality, and sustainability will be discussed.
