Les motivations du vigneron en quête de l’expression “terroir”

Abstract

Jusqu’en 1985 les vendanges ont été réalisées par parcelles et l’assemblage après fermentation. Lors des vendanges 1985, j’ai pu constater à la perception gustative une rupture d’harmonie du vin lors des assemblages même partiels de raisins provenant de parcelles différentes. J’ai noté parallèlement une bonne réaction de la clientèle pour une plus grande personnalisation du produit. De ce fait, j’ai été amené à rechercher les limites objectives du terroir d’une cuvée et par un affinement constant et permanent des paramètres spécifiques à chacun des terroirs.

L’évolution de mon approche a été ordonnée de la façon suivante :
– observations géo-pédologique des parcelles avec dégustation de raisins,
– constatation des différences de type de maturité et de vitesse de maturité des raisins,
– perception du climat propre à chacune des parcelles : rôle de la topographie, de l’altitude, du vent, de la proximité de l’eau.
– adaptation progressive du travail jusqu’à la cueillette des raisins aux différents type de terroir.

Foliar application of urea improved the nitrogen composition of Chenin grapes

The nitrogen composition of the grapes directly affects the developments of alcoholic fermentation and influences the final aromatic composition of the wines. The aim of this study was to determine the effect and efficiency of foliar applications of urea on the nitrogen composition of grapes. This study was carried out during 2023 vintage and in the Chenin vineyard located in Estacion Experimental Mendoza (Argentina). Three urea concentrations 3, 6 and 9 Kg N/ha (C1, C2, and C3, respectively) and control (T) were applied in this vineyard at veraison.

Marketing terroir wines

The markets for quality wine are becoming more competitive as newer producers emerge and traditional producers improve their quality. The concept of terroir is one way to differenzi­ate wines in a competitive market and to enhance producer income.

Towards an ecological architecture inspired by underground cellars: An example of the thermal inertia of Moldovan underground cellars and new geothermal and Canadian well approaches

The search for underground shelters is one of the oldest forms of human habitation, providing refuge in extreme environments such as deserts and polar regions.

Chemical activation of ABA signaling in grapevine through ABA receptor agonists

Grapevine (Vitis vinifera) and its derived products, in terms of cultivated area and economic volume, constitute the most relevant fruit crop in the world (7.5 million cultivated hectares). In the current context of climate change, the wine sector faces unprecedented challenges to satisfy a growing demand for wines of greater quality through sustainable viticulture. Global warming threatens quality wine production in Mediterranean wine regions in particular. The increase in heatwaves and drought episodes accelerate the vine phenology and alter the ripening and composition of grapes and wine. Extreme abiotic stress episodes compromise grape production and plant survival, intensifying the pressure on the use of limited resources like water. Abscisic acid (ABA) is an important hormone in the ripening of certain fruits and in plant response to abiotic stress.

Irrigation frequency in four grapevine red varieties in Spain. Effect on must volatile composition

The irrigation water management in the vineyard is a crucial aspect to obtain sustainable quality production over time. Previous studies have set the water requirements to be applied in the vineyard at 30 % of the reference evapotranspiration (ET0), although there are no studies that settle the effects of the frequency of irrigation application on red varieties in Spain. The present study contemplates the application of deficit irrigation (30 % ET0) applying a weekly dose in a single irrigation (T07) or in two irrigation events (T03) per week. The study has been carried out in 2021-2022 with four red varieties in different Spanish wine regions: Garnacha Tinta (Badajoz), Tempranillo (Valladolid), Syrah (Albacete) and Mencía (Lugo). The effects of irrigation frequency on must volatile composition have been evaluated through GC-MS.
