Response of the plant: a chief element for the characterisation of wine-growing “terroirs”

Abstract

Face au risque de banalisation des produits agroalimentaires, un intérêt toujours plus marqué se développe en faveur des produits du terroir. La viticulture a été pionnière en la matière et les études des effets du milieu naturel sur la qualité et la typicité des produits sont nombreuses et diverses.
La caractérisation des terroirs peut être faite facteur par facteur en analysant l’incidence des différents critères pris séparément. Elle peut être orientée vers la techerche de marqueurs susceptibles d’intégrer des facteurs liés au sol, au climat et à la plante.
L’approche peut être aussi globale par l’utilisation de systèmes d’information géographiques (SIG) capables de combiner un nombre très élevé de critères, grâce à des outils informatiques très puissants.
Indépendamment de la méthodologie choisie, les informations récoltées doivent être validées par l’étude du comportement de la plante en relafon avec la valeur des produits obtenus dans des terroirs déterminés. Le choix des méthodes de caractérisation va dépendre du niveau d’échelle souhaité qui peut aller de la micro parcelle à l’ensemble d’une région ou d’un pays. Il sera également fonction des objectifs recherchés, qui peuvent être divers, de la classification des crus à l’adaptation d’itinéraires viticoles appropriés.

Vis-à-vis the risk of vulgarising the agroalimentary products, an increasingly shown interest develops in favour of the “terroir” products. The viticulture blazed a trail in this field, and the studies of the effects of the natural environment on the quality and on the originality of the products are numerous and varied.
The characterisation of wine-growing “terroirs” can be done factor by factor by analysing the incidence of the various individual criteria. It can be directed towards the search for markers likely to integrate factors linked to the soil, the climate and the plant.
The approach can also be global by using geographical information systems (GIS) able to combine a very high number of criteria thanks to very powerful data-processing tools.
Independently of the chosen methodology, collected information must be validated by the study of plant behaviour in relation to the value of the products obtained in given “terroirs”. Choice of the characterisation methods will depend on the desired scale level, which can go from micro plot to a whole area or country. It will be also a function of the required objectives which can be diverse, from the vintage classification to the adaptation of suitable wine­growing practices.

Toward an automatic way to identify red blotch infected vines from hyperspectral images acquired in the field

Vineyards are affected by different virus diseases, which can lower yield and affect the quality of grapes. Grapevine red blotch disease is one of them, and no curative solution exists. Once infected, a vine must be removed and replaced with a virus-free vine (aka roguing). Screening vineyards to look for symptoms can be time-consuming and needs well-trained experts. To improve this process, we conducted an experiment identifying infected vines using a hyperspectral camera in the field.

METHYL SALICYLATE, A COMPOUND INVOLVED IN BORDEAUX RED WINES PRODUCED WITHOUT SULFITES ADDITION

Sulfur dioxide (SO₂) is the most commonly used additive during winemaking to protect wine from oxidation and from microorganisms. Thus, since the 18th century, SO₂ was almost systematically present in wines. Recently, wines produced without any addition of SO₂ during all the winemaking process including bottling became more and more popular for consumers. A recent study dedicated to sensory characterization of Bordeaux red wines produced without added SO₂, revealed that such wines were perceived differently from similar wines produced with using SO₂ and were characterized by specific fruity aromas and coolness1,2.

Elaboration des cartes conseils pour une gestion du terroir à l’échelle parcellaire: utilisation d’algorithmes bases sur des paramètres physiques du milieu naturel

The “Anjou Terroirs” programme aims at bringing the necessary scientific basis for a ratio­nal and reasoned exploitation of the technical itinerary of the terroir. The scale study is 1/12500. For the mapping, many parameters, such as the granulometry or the depth of soil are observed to each point of caracterisation.

THE INFLUENCE OF COMMERCIAL SACCHAROMYCES CEREVISIAE ON THE POLY-SACCHARIDES AND OTHER CHEMICAL PROFILES OF NEW ZEALAND PINOT NOIR WINES

Wine polysaccharides (PS) play an important role in balancing mouthfeel and stability of wine and even influence aroma volatility. Despite this, there is limited research into the effect of winemaking additives on the polysaccharide profile and other macromolecules of New Zealand (NZ) Pinot noir wine. In this study the influence of a selection of commercial S. cerevisiae strains on the chemical profile, including polysaccharides, of New Zealand Pinot noir (PN) wine was investigated. Research scale PN fermentations using five strains of commercially available S. cerevisiae (Lalvin EC1118 and RC212, Levuline BRG YSEO, Viallate Ferm R71 and R82) were undertaken. PS were qualified and quantified using HPLC-RID.

Effects of mulching with municipal solid waste (MSW)-compost on the soil microbiota and decomposition activity in a productive vineyard in Apulia (Italy)

Application of municipal solid waste (MSW)-compost as a mulching material in vineyards supports sustainable practices and aligns with both circular economy and zero-waste principles.
