Une méthode d’étude synthétique du paysage

Abstract

a) le vin, produit qualitatif et convivial à souhait, favorise un support visuel, même pour une étude scientifique car il renvoie à l’image du terroir, en particulier par son paysage visible.
b) le paysage viticole assez ouvert par définition favorise ce type d’approche.
c) le cadre de l’Essai Terroir mené par l’U.R.V.V. (I.N.R.A. – Angers) comporte 15 micro-parcelles de 100 souches, et nécessite à cette échelle des relevés précis du milieu, d’oîi des prises de vue systématiques, du centre de la parcelle, sur 360°, au 50 mm, à 1 m70 su sol et à l’horizontale. Ce type de relevé réalisable aussi au clisimètre ou au téodolithe, permet de saisir la totalité des composantes paysagères environnantes, puis de les grouper en masses homogènes qui, au-dessus des rangs de vigne, peuvent être des masques à l’ensoleillement et au vent. La perspective estompe naturellement l’influence de ces masques avec l’éloignement, par diminution de leur importance visuelle, l’épaisseur de ceux-ci ne peut être fournie que par la photographie aérienne, exploitée ici de source IGN.
Le recours à la photo possède l’avantage sur les appareils de mesure des distance et d’angles solides, d’aboutir à un document souvent flatteur et surtout palpable, mais dont la mise en oeuvre demeure plus longue et coûteuse.
d) la vue frontale sur 360° est scindée en deux panoramiques : l’un centré au Nord, l’autre au Sud par commodité de représentation spatiale quant à leur lecture.
La vue verticale ou aérienne n’est prise en compte que dans un rayon de 500 m du centre de la parcelle, distance semblant raisonnable quant à l’influence des masques sur celle-ci.

Typology of Terroirs around the world

It seems implausible that the geographical development of the vineyards could have been affected by a shift in the positions of the Earth’continents

Zoning methods in relation to the plant

The characterization of the plant is the obliged pathway between the environment and the product. The responses of the plant amplify or reduce the variations of the environment, while determining directly the type and the quality of the products. These results are inscribed inside the Viticultural Terroir Unit (VTU). VTU is the complex interaction between the Basic Terroir Unit or BTU (interaction mesoclimate x soil/subsoil), the genotype (variety x rootstock), the management system, the oenological technologies. Thus, at the most complex level, a global biological triptych is found again : environment (source) x plant (structure) = produced and exchanged substances.

IBMP-Polypenol interactions: Impact on volatility and sensory perception in model wine solution

3-Isobutyl-2-methoxypyrazine (IBMP) is one of the key molecules in wine aroma with a bell pepper aroma and a very low threshold in wine, 1-6 ng/L for white wine and 10-16 ng/L in red wine1. The differences in these thresholds are likely due to IBMP-non volatile matrix interactions. It has indeed been shown that polyphenols may influence the volatility of flavor compounds2. In the present study, we focus on IBMP-polyphenols interactions in relation to volatility and sensory perception in model wine solution. Methods: 1. GC-MS Static Headspace Analysis: Samples were analyzed by Static headspace analysis with an Agilent 7890A gas chromatograph coupled to HP 5975C mass spectrometry detector (Agilent Technologies, Santa Clara, CA, USA).

Differences in the chemical composition and “fruity” aromas of Auxerrois sparkling wines from the use of cane and beet sugar during wine production.

The main objective of this study was to establish if beet sugar produces a different concentration of “fruity” volatile aroma compounds (VOCs), compared to cane sugar when used for second alcoholic fermentation of Auxerrois sparkling wines. Auxerrois base wine from the 2020 vintage was separated into two lots; half was fermented with cane sugar and half with beet sugar (both sucrose products and tested for sugar purity). These sugars were used in yeast acclimation (IOC 2007), and base wines for the second fermentation (12 bottles each). Base wines were manually bottled at the Cool Climate Oenology and Viticulture Institute (CCOVI) research winery. The standard chemical analysis took place at intervals of 0, 4 weeks, and 8 weeks post-bottling. Acidity and pH measurements were carried out by an auto-titrator. Residual Sugar (g/L) (glucose (g/L), fructose (g/L)), YAN (mg N/L), malic acid, and acetic acid (g/L) were analyzed by Megazyme assay kits. parameters were analyzed by Megazyme assay kits. Alcohol (% v/v) was assessed by GC-FID. VOC analysis of base wines, finished sparkling wines, as well as the two sugars in model sparkling wine solutions, was carried out by GC-MS. VOCs included ethyl octanoate, ethyl hexanoate, ethyl butanoate, ethyl decanoate, ethyl-2-methylbutyrate, ethyl-3-methylbutyrate, ethyl 2-methyl propanoate, ethyl 2- hydroxy propanoate, 1-hexanol, 2-phenylethan-1-ol, ethyl acetate, hexyl acetate, isoamyl acetate and 2-phenylethyl acetate.

An analytical framework to site-specifically study climate influence on grapevine involving the functional and Bayesian exploration of farm data time series synchronized using an eGDD thermal index

Climate influence on grapevine physiology is prevalent and this influence is only expected to increase with climate change. Although governed by a general determinism, climate influence on grapevine physiology may present variations according to the terroir. In addition, these site-specific differences are likely to be enhanced when climate influence is studied using farm data. Indeed, farm data integrate additional sources of variation such as a varying representativity of the conditions actually experienced in the field. Nevertheless, there is a real challenge in valuing farm data to enable grape growers to understand their own terroir and consequently adapt their practices to the local conditions. In such a context, this article proposes a framework to site-specifically study climate influence on grapevine physiology using farm data. It focuses on improving the analysis of time series of weather data. The analytical framework includes the synchronization of time series using site-specific thermal indices computed with an original method called Extended Growing Degree Days (eGDD). Synchronized time series are then analyzed using a Bayesian functional Linear regression with Sparse Steps functions (BLiSS) in order to detect site-specific periods of strong climate influence on yield development. The article focuses on temperature and rain influence on grape yield development as a case study. It uses data from three commercial vineyards respectively situated in the Bordeaux region (France), California (USA) and Israel. For all vineyards, common periods of climate influence on yield development were found. They corresponded to already known periods, for example around veraison of the year before harvest. However, the periods differed in their precise timing (e.g. before, around or after veraison), duration and correlation direction with yield. Other periods were found for only one or two vineyards and/or were not referred to in literature, for example during the winter before harvest.
