Montpellier vine & wine sciences (M-WineS)

Abstract

Context and purpose of the study – The Occitanie Region is the first vine-growing area in France: 270 000 hectares of vineyard and an annual production of 15 million hectoliters. Its annual income reaches 1 900 million euros, of which 900 million euros in export.The vine and wine sector is facing many issues: inputs reduction, adaptation to climate change, maintaining the production competitiveness, digital tools integration in production and transformation processes, and the production of quality wines meeting the consumer demand.

Objectives – Montpellier Vine & Wine Sciences aims to develop the Montpellier research-educationinnovation cluster in the vine and wine sector.The goal is to bring Montpellier research and education actors all together in order to ease exchanges among research subjects: French Institute of Agronomic Research, University of Montpellier, Montpellier SupAgro, National Research Institute of Sciences and Technology for Environment and Agriculture. There is an involvement of 15 research structures in M-WineS, among them 150 scientists, 13 research labs and 2 experimental units. The M-WineS collective offers higher education and welcomes 400 students each year.The purpose of M-WineS is to better answer the vine & wine sector issues – environmental footprint reduction, adaptation to climate change, quality construction for the market, digital transition – and to strengthen the site’s visibility and attractiveness. M-WineS works with doctoral schools and community tools, and has already several links with the vine and wine sector’s stakeholders: industrial clusters, competitiveness hub, Vine and Wine cooperatives, Regional and Departmental Chambers of Agriculture, Vine inter-professions. M-WineS will also reinforce its links with international Universities.

Some representative projects

– A panel of 279 accessions of Vitis vinifera vine to develop integrated projects from gene to glass

The aim is to have a representation panel of the Vitis vinifera genetic diversity with 279 cultivars, to identify the genetic basis of the vine’s traits of interest by Genome-Wide Association Study. Exploring genetic basis and eco-physiology of the plants, linked with wine characteristics, will allow scientists to select and create grape varieties consuming less inputs, more adapted to constraining climates, and meeting the consumers demand if quality wine.

– The production competitiveness observatory

The engagement of all the concerned research structures is an indispensable asset to build an observatory of different situations, evolutions, analysis tools of the factors determining industrial competitiveness, and action-levers allowing a rising competitiveness in the short term.

This observatory will reinforce partnership with industrials and institutional stakeholders of the sector.

– A Vine & Wine Sciences researchers school

This event aims at encouraging PhD students and young scientists to learn about other fields of study. This will allow them to know more about other approaches to deal with the key issues in various fields.

– MOOC “vine&wine sciences”

The aim is implement a MOOC dedicated to introduce to vine and wine sciences with an extension of available languages, queez, videos…

Volatile compounds of base wines for the production of Lessini Durello sparkling wine

AIM Durello is a sparkling wine produced in the Lessini mountains near Verona. The wine is made from Durella grapes, a native white grape variety with a particularly high acidity. In spite of the small production area (375 ha for only 35 producers), there is a growing interest in this product. However, little is known about the aromatic profiles of these wines. The aim of this work was to characterize the aroma profile of Durella base wines suitable for the production of Lessini Durello sparkling wine. METHODS 14 base wines from Durella grapesfrom different producers were used for this study. Solid Phase Microextraction (SPME) and Solid Phase Extraction (SPE) sampling techniques coupled to GC-MS analysis allowed to identify and quantify a total of 62 volatile compounds. RESULTS Durello base wines showed relatively high levels of vitispirane, ß-damascenone, ß-citronellol and esters.

Towards more coherent rules for alcohol labelling in the European Union

In its 2020 beating cancer plan, the european commission announced plans for mandatory warning signs for alcoholic beverages. However, no concrete legislative proposal has been put forward so far. Instead, ireland passed national legislation in 2023 that requires warning signs for all alcoholic beverages from 2026. Despite significant effects for the common market, the eu commission did not this challenge this law in the so-called tris notification procedure. We argue that the commission’s inaction is consistent with the case law of the european court of justice: in the absence of harmonized rules, member states have a large margin of discretion to enact national health measures.

CONTRIBUTION OF VOLATILE THIOLS TO THE AROMA OF RIESLING WINES FROM THREE REGIONS IN GERMANY AND FRANCE (RHEINGAU, MOSEL, AND ALSACE)

Riesling wines are appreciated for their diverse aromas, ranging from the fruity fresh characters in young vintages to the fragrant empyreumatic notes developed with aging. Wine tasters often refer to Riesling wines as prime examples showcasing terroir, with their typical aroma profiles reflecting the geographical provenance of the wine. However, the molecular basis of the distinctive aromas of these varietal wines from major Riesling producing regions in Europe have not been fully elucidated. In this study, new lights were shed on the chemical characterization and the sensory contribution of volatile thiols to Riesling wines from Rheingau, Mosel, and Alsace. First, Riesling wines (n = 46) from the three regions were collected and assessed for their aroma typicality by an expert panel.

BIOSORPTION OF UNDESIRABLE COMPONENTS FROM WINE BY YEAST-DERIVED PRODUCTS

4-Ethylphenol (EP) in wine is associated with organoleptic defects such as barn and horse sweat odors. The origin of EP is the bioconversion reaction of p-coumaric acid (CA), naturally present in grapes and grape musts by contaminating yeasts of the genus Brettanomyces bruxellensis.
Yeast cell walls (YCW) have shown adsorption capacities for different compounds. They could be applied to wines in order to adsorb either CA and/or EP and thus reduce the organoleptic defects caused by the contaminating yeasts.

Impact of dried stems in winemaking on Veneto Passito wines

The use of stems during fermentation is generally avoided due to the herbaceous off-odors they can impart to the wine. [1].
