Viticultural zoning applications at the detailed scale of a cooperative winery: terroirs in St­hilaire-d’Ozilhan (AOC Côtes-du-Rhône)

Abstract

[English version below]

La maîtrise de la typicité du vin s’élabore au niveau local ou communal d’une exploitation viticole et/ou d’une cave, unité de vinification. La cave coopérative de Saint-Hilaire­-d’Ozilhan (AOC Côtes-du-Rhône), dont le territoire communal s’étend sur une superficie de 1 670 ha, couvre près de 310 ha cultivés en vigne. Elle réalise des vinifications «au terroir», en utilisant des regroupements d’unités de sol en 9 unités de terroir potentiellement viticoles, définies en s’appuyant sur la parenté des substrats. Diverses sélections d’une même unité peuvent aboutir aussi à des vins différents, ce qui suggère une hétérogénéité spatiale de certaines unités définies. Une carte des terroirs issue d’une approche par l’analyse spatiale géomorpho-pédologique est par ailleurs disponible pour la cave coopérative, munie de son niveau plus détaillé, la carte des unités de pédopaysage. La comparaison des différentes cartes disponibles suggère diverses options applicables aux sélections de vendange. Par ailleurs, l’utilisation de fonctions de pédotransfert a permis d’estimer la réserve utile.

Wine quality needs to be monitored at the detailed local scale of the winery or viticultural farm territory. The territory covered by the cooperative winery of Saint-Hilaire-d’Ozilhan (AOC Côtes-du-Rhône), is a 1 670 hectares-commune area, nearly 310 hectares of which are grown into vine. This winery has been working for nearly a decade on geographical and enological mana gement. Wine-making processes are based on 9 “terroir” land divisions, defined with the substrata indicated in soil map units. Distinct selections of the same unit can lead to different wines, thus indicating the spatial heterogeneity of some of the units defined.
A zoning obtained from soil and landform spatial analysis, is available for this winery from another source, with a detailed soil landscape map. The comparison of the varied documents available may apply to different harvest selections.

Effect of intra‐vineyard ripeness variation on the efficiency of commercial enzymes on berry cell wall deconstruction under winemaking conditions

Intra-vineyard variation grape berry ripening occurs within bunches, between bunches on the same vine and between vines. Although it is assumed that such variation also occurs at the grape berry cell wall level, no study to data has investigated in any depth. Here we have used a intra-vineyard panel design to investigate pooled bunches from six vines (per panel) in the context of a winemaking scenario. The dissected vineyard was harvested by separate panels, where each panel was then subjected to a standard winemaking procedure with or without the addition of three different enzyme preparations for maceration.

Monitoring grapevine downy mildew epidemics with SkySat and PlanetScope imagery

Grapevine downy mildew (GDM), caused by the oomycete Plasmopara viticola, is one of the most destructive diseases of Vitis vinifera worldwide. All V. vinifera cultivars are susceptible to P. viticola infection, and epidemics can spread across an entire vineyard within a matter of weeks. Severe outbreaks cause substantial reductions in yield and fruit quality. Tracking GDM spread by manual scouting is time-consuming and unfeasible over large spatial extents.

OENOLOGICAL TANNINS FOR PREVENTING THE LIGHT-STRUCK TASTE IN WHITE AND ROSÉ WINES

The light exposure of wine can be detrimental as a relevant loss of aromas takes place [1] and light-induced reactions can occur. The latter involves riboflavin (RF), a photosensitive compound, that is fully reduced by acquiring two electrons. When the electron-donor is methionine, the light-struck taste (LST) can appear leading to cooked cabbage, onion and garlic odours-like [2]. The use of oenological tannins can limit the appearance of LST in both model wine [3] and white wine [4]. This research aimed to evaluate the impact of certain oenological tannins, selected in a previous study as the most effective against LST [5], in both white and rosé wines.

Impact of climate change on the aroma of red wines: a focus on dried fruit aromas

The volatile composition of grapes (free and bound forms) contributes greatly to the varietal aroma and quality of wines. Several agronomical parameters affect grapes composition and wine quality: maturity level at harvest, water status, and the intensity of sun exposure.
