Use of the stics crop model as a tool to inform vineyard zonages

Abstract

[English version below]

STICS est un modèle de culture développé à l’INRA (France) depuis 1996. Il simule les bilans de carbone, d’eau et d’azote dans le système culture-sol, piloté par des données climatiques journaliéres. Il calcule à la fois des variables agricoles (rendement en quantité et qualité) et environnementales (pertes en eau et en azote). Une des originalités de STICS est son adaptabilité à de nombreuses cultures (herbacées, ligneuses, annuelles, pérennes) rendue possible par le choix de paramètres génériques et d’options de formalismes. Le travail présenté traite, dans un premier temps, des spécificités de STICS pour la vigne en terme de bilan trophique, de fonctionnement énergétique et hydrique et d’estimation des teneurs en sucre en en eau du raisin. Nous montrons ensuite diverses sorties du modèle qui permettent de caractériser des terroirs du vignoble des Côtes du Rhône.

STICS is a crop model developed at INRA (France) since 1996. It simulates the carbon, water and nitrogen balances of the crop-soil system driven by daily climatic data. It calculates both agricultural variables (yield in terms of quantity and quality) and environmental variables (water and nitrogen losses). One of the key elements of STICS is its adaptability to various crops (herbaceous, ligneous, annuals, perennials) made possible by the choice of generic parameters and options for both crop physiology and crop techniques. The present work deals first with the particularity of STICS to simulate vineyard in terms of trophic balance, energetic and water functioning and assessment of sugar and water contents of grape. Second it shows the various outputs which can be calculated by the model in order to characterize typical Côtes du Rhône zones.

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

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.

Beneficial effects of moderate consumption of Teran red wine on blood lipid profile: a preliminary study on healthy volunteers

Moderate wine consumption may impact several human health aspects, among others as a result of phenolic compounds present in wine and their bioactive properties. The aim of this study was to determine whether six weeks of daily, moderate Teran red wine consumption affects the levels of total cholesterol, high-density lipoprotein cholesterol – HDL, low-density lipoprotein cholesterol – LDL, and triglycerides. Sixty-eight healthy adults (46 women and 22 men) aged 25-64 years voluntarily agreed to participate in the study.

Closure permeability modulates the aroma expression of monovarietal white wines during bottle ageing

Bottle ageing is a critical period for wine quality, as it undergoes various chemical and sensory changes during storage. Ideally, a phase of qualitative ageing, during which wine sensory quality improves, is followed by a decline of quality. Understanding how different oenological variables influence these phases is a key challenge in modern winemaking. Recent studies highlighted the significant role of oxygen in modulating reactions involving volatile and non-volatile components, impacting aroma evolution during bottle aging. Oxygen exposure of wine during bottle ageing is mediated by closure.

Fractal analysis as a tool for delimiting guarantee of quality areas

The pioneering work of Mandelbrot in the 70’s for building the fractal theory lead rapidly to many interesting applications in different fields such as earth sciences and economy.

Integrative grape to wine metabolite analyses to study the vineyard “memory” of wine

Wine production is a complex multi-step process and the end-product is not easily defined in terms of composition and quality due to the diversity of the raw materials (grapes) and the biological agents (yeast and bacteria) used/present during the fermentation. Furthermore, linking what happens in the vineyard to the wine fermentation and ultimately to characteristics in the wine during ageing
