Changing the scale of characterization of a wine area: from a single protected designation of origin to a vineyard Loire Valley observatory (viLVO)

Dec 3, 2021 | IVES Conference Series, Terroir 2010, Vineyard management for environment valorisation (T2010)

Terroir is increasingly important today in wine markets. In a large wine production area such as the Loire Valley, the whole territories/terroirs can be distinguished according to different combinations of geological, soil, climatic and landscape features but are also characterized by their differences and likenesses in terms of combinations of terroir units and practices.

Long-term vineyard sustainability index

Dec 3, 2021 | IVES Conference Series, Terroir 2010, Vine growing and environmental sustainability (T2010)

The impact of viticulture on soil can be determined by comparing the biophysical properties that represent soil health at a particular site and depth with those same properties in soil considered to represent the ‘pre-vineyard’ state (the headland). Information gathered by this method shows the changes in soil properties following the change to viticulture depend on individual vineyard management and environment.

Vino e paesaggio: materiali per il governo del territorio vitivinicolo. Il piano regolatore delle città del vino

Dec 3, 2021 | IVES Conference Series, Terroir 2010, Vine growing and environmental sustainability (T2010)

S’intende per Piano Regolatore delle Città del Vino la metodologia per redigere la parte strutturale dello strumento comunale di governo del territorio. Parliamo, infatti, del principale strumento comunale di governo del territorio, così come è venuto maturando nella riflessione delle Città del Vino, strumento che si misura con la sfida di governare tutto il territorio in modo coerente e sostenibile, a partire dal riconoscimento del valore del “sistema vigneto” e della sua intrinseca fragilità.

Analyse climatique à l’échelle des Coteaux du Layon

Dec 3, 2021 | Historic and future climate variability and climate change: effects on vocation, stress and new vine areas (T2010), IVES Conference Series, Terroir 2010

Les études d’impact du climat sur la vigne nécessite de descendre à des échelles très fines car les facteurs climatiques sont tributaires de la topographie, la végétation, les expositions … Dans le cadre du programme ANR-JC Terviclim, 22 capteurs ont été installés dans les vignobles des Coteaux du Layon afin de caractériser le climat particulier de ces terroirs. L’analyse des températures montre de fortes disparités entre les data loggers et pourtant situés parfois sur les mêmes parcelles ou sur des parcelles voisines. Les indices bioclimatiques tels les degrés jours sont également contrastés suivant la situation des capteurs sur les coteaux.

Influenza dell’esposizione del vigneto sulla maturazione dell’uva

Dec 3, 2021 | Historic and future climate variability and climate change: effects on vocation, stress and new vine areas (T2010), IVES Conference Series, Terroir 2010

Lo studio è stato condotto in vigneti commerciali di Vitis vinifera cv Nebbiolo localizzati in Piemonte, Italia del Nord-Ovest, intorno alla sommità di una collina. L’obiettivo dello studio è stato di determinare come l’esposizione del vigneto possa influenzare il comportamento vegetativo della vite, il manifestarsi delle fasi fenologiche, e la cinetica di maturazione dell’uva con particolare riguardo all’accumulo di antociani e flavonoli.

Impact of harvest date on the terroir expression and the aroma profile of Touraine Sauvignon wines

Dec 2, 2021 | IVES Conference Series, Terroir 2010, Vineyard management for environment valorisation (T2010)

L’objectif d’une étude sur trois années vise, pour des terroirs différents et connus pour le profil des vins qui en sont issus, à exploiter au mieux le potentiel des raisins en optimisant la date de récolte ; pour chacun des trois terroirs, les minivinifications sont réalisées à partir de trois dates de récolte . Il s’avère, grâce à un suivi analytique important (sol, précurseurs et arômes) et une caractérisation organoleptique bien encadrée (analyse sensorielle pertinente et objective), que le choix de la date de récolte, en fonction du terroir, a une incidence sur le profil du vin et devient un outil pour l’élaborateur.

Nov 24, 2021 | IVES Conference Series, Terroir 2010, World Wine Regions: their conservation, grape varieties and wine tipicity (T2010)

La superficie vitata della provincia di Modena é per circa il 70% interessata dai Lambruschi, famiglia di vitigni tipica dei territori pianeggianti emiliani. Tra questi, i più rappresentativi sono il Lambrusco di Sorbara, il Lambrusco salamino e il Lambrusco grasparossa che, unico esempio, predilige gli ambienti collinari della provincia. Nel quinquennio 2001-2005 la Provincia di Modena ed il C.R.P.V. hanno coordinato la zonazione viticola di tutto il territorio dei Lambruschi modenesi, i cui risultati hanno consentito di individuare, in ciascuna zona D.O.C., alcune Terre in cui cias.

Three proximal sensors to estimate texture, skeleton and soil water storage in vineyards

Nov 23, 2021 | Geology and Soil: effects on wine quality (T2010), IVES Conference Series, Terroir 2010

Proximal sensors are becoming widely used in precision viticulture, due to the quick, easy and non-invasive identification of soil spatial variability. The apparent soil electrical conductivity (ECa) is the main parameter measured by sensors, which is correlated to many factors, like soil water content, salinity, clay content and mineralogy, rock fragments, bulk density, and porosity.

The geological and geomorphological events that determine the soil functional characters of a terroir

Nov 23, 2021 | Geology and Soil: effects on wine quality (T2010), IVES Conference Series, Terroir 2010

The geology of a region is deemed to be an important component of terroir, as it influences the shape of the landscape and the climate of vineyard. The nature of rock and the geomorphological history of a terroir affect soil physical and chemical composition through a dynamic interplay with the changes of climate, vegetation and other living organisms, as well as with man activities.
