Terroirs de Balagne: focus sur le Vermentinu

Abstract

[English version below]

Depuis 2002, le CIVAM de la région Corse, a entrepris une étude des terroirs viticoles de l’appellation AOC Corse-Calvi (Balagne), comprenant la cartographie des terroirs à potentialité viticole, l’étude a gronomique et œnologique des 3 principaux cépages de l’appellation : Vermentinu (blanc), Niellucciu et Sciaccarellu (rouge et rosé) sur les différents terroirs cartographiés.
La cartographie des terroirs a été réalisée sur SIG à partir d’un ensemble de facteurs naturels représentés sous forme de cartes numérisées géoréférencées, scindé en 2 groupes:
– le sol (prenant en compte: la nature du sol et du sous-sol, la réserve en eau, l’hydromorphie) – le morphoclimat (composé des cartes de: pente, expositions, altitudes, distances au rivage, pluviométrie, somme des températures supérieures à 10°c, insolation théorique).
La carte morphoclimatique a été obtenue en appliquant à l’ensemble des cartes le constituant, un traitement statistique en ACP. La carte finale des terroirs a été obtenue par croisement entre la carte des sols et la carte du morphoclimat. 24 terroirs ont ainsi é té identifiés. Une étude agronomique et œnologique du Vermentinu a été réalisée sur 5 terroirs ( soit, près de 63% des surfaces à vocation viticole de l’appellation), grâce au suivi d’un réseau de 7 parcelles de vigne possédant les mêmes caractéristiques ( âge, clone, porte-greffe, taille, palissage, densité de plantation, SFE…). Les contrôles ont été effectués au niveau de la physiologie de la vigne (débourrement, véraison, maturité, stress hydrique), de la récolte (état sanitaire, rendement, fertilité, poids des baies et des grappes), des vinifications (les raisins de chaque parcelle ont été vinifiés de manière identique, les vins ont été analysés et dégustés par un jury de professionnels). Ce travail a été réalisé entre 2002 et 2007. Des résultats intéressants ont été obtenus au niveau de la physiologie de la vigne, de la production et des paramètres physico-chimiques des vins. Des différences marquées ont été observées lors des dégustations. 4 profils sensoriels ont été identifiés sur les 5 terroirs étudiés, leur potentiel de vieillissement a également été défini.
– Cette étude a permis de connaître, dans un premier temps, la capacité de chaque type de terroir à marquer l’expression des vins blancs de Vermentinu. Ces caractéristiques pouvant être exacerbées ou atténuées par l’effet millésime.

Since 2002, the CIVAM region Corsica, undertook a study viticultural land designation AOC Corse-Calvi (Balagne), including mapping to wine-growing potential terroirs, Study agronomy and œnological the 3 main grape varieties of the appellation: Vermentinu (white), Niellucciu and Sciaccarellu (red and rose) on different land mapped.
Terroir mapping was conducted on GIS to a set of natural factors represented as digitized geo-referenced maps, split into 2 groups:
– soil (taking into account: nature of soil and the sub soil, water reserve, the hydromorphie)
– the morphoclimat (cards consisting of: slope, exhibitions, altitudes, distances from shore, pluviometry, temperatures above 10°c, theoretical insolation sum).
The morphoclimatique card was obtained by applying cards all the constituent, a statistical treatment in ACP. The final terroir card was obtained by cross between the soil card and the morphoclimat card. 24 terroirs were thus identified. Agronomy and œnological from the Vermentinu study was conducted on 5 terroirs (either 63% surfaces of appellation) through monitoring a network of 7 plots of vines that have the same characteristics (age, clone, rootstock, vineyard, size, density of planting, SFE…). The checks have been performed at physiology of the vine (débourrement, veraison, maturity, water stress), harvest (health, yield, fertility, weight arrays and pools), vinifications (each vineyard grapes have been vinified identically, wines have been analyzed and tasted by a jury of professionals). This work was carried out between 2002 and 2007. Interesting results were obtained at the physiology of vine, production and physico-chemical parameters of wines. Marked differences have been observed during the tasting. 4 sensory profiles have been identified on 5 studied terroir, their potential for ageing has also been defined.
This study led to know, first, the capacity of each terroir type to mark the expression Vermentinu white wines. These characteristics may be exacerbated or mitigated by the effect millésime.

Successful technology transfer of the early defoliation technique in cv. Mandó, an autochthon variety from south-east Spain

In the old-world viticulture autochthonous varieties are an important inheritance because they can provide wines with authenticity and distinction. Cultivar Mandó is an almost extinguished variety from the south-east

Sensory profile: a tool to characterize originality of wines produced without sulfites

A trend to reduce chemical inputs in wines exists, especially sulfur dioxide (SO2). This additive is widely used due to its antioxidant, antiseptic and antioxidasic properties. During without sulfites vinification, bioprotection by adding yeast on harvest could be a sulfites alternative. With extension of this wine market, sensory impact linked to sulfites absence and/or sulfites alternative should be evaluated. That’s what this approach proposes to do, focusing on sensory characteristics of wines produced with or without SO2 addition during the winemaking process. METHODS: Wines were elaborated from Merlot grapes of two maturity levels according to three modalities: SO2, without SO2 and bioprotection on harvest (mix of Torulaspora delbrueckii and Metschnikowia pulcherrima). SO2 modality was sulfited throughout the winemaking and aging processes whether other modalities received any addition. After two years of aging, sensory studies were carried out with a specific panel for one month. First, descriptors were generated to differentiate the wines, then panelists were trained on these specific descriptors for five sessions and finally wines sensory profiles were elaborated

Searching for the sweet spot: a focus on wine dealcoholization

It is well known that the vinification of grapes at full maturation can produce rich, full-bodied wines,
with intense and complex flavour profiles. However, the juice obtained from such grapes may have very
high sugar concentration, resulting in wines with an excessive concentration of ethanol. In addition, the decoupling between technological maturity and phenolic/aromatic one due to global warming, exacerbates this problem in some wine-growing regions. In parallel with the increase of the mean alcohol content of wines on the market, also the demand for reduced alcohol beverages has increased in recent years, mainly as a result of health and social concerns about the risks related to the consumption of alcohol.
