Red Grenache variety in Rhône Valley : impact of “terroir” and vintages on the aromatic potential of the grapes

Abstract

Le cépage Grenache noir, de par son originalité et sa représentativité, participe très directement à la qualité et à la typicité des vins de la vallée du Rhône. Il est généralement apprécié pour sa palette aromatique variée et pour les caractères de rondeur et de souplesse qu’il confère aux vins. Depuis 1995, l’Institut Rhodanien a mis en place un réseau de parcelle de référence représentative des différents type de terroir présent en zone méridionale de l’Appellation Côtes du Rhône (TRUC, 1997; VAUDOUR et al, 1996). Les publications sur la composition aromatique des raisins et des vins est très abondante, mais seulement quelques articles sont parus sur le cépage grenache PAUMES et al, 1986).Comme quelques autres cépages référencés comme « neutres », ce cépage engendre des vins très typés, dont la qualité aromatique est reconnu à travers le monde entier. Une première étape nous a permis d’étudier d’une manière systématique l’ensemble des composés aromatiques présents à l’état libre ou sous forme glycosylée (précurseurs d’arômes) au cours de 3 millésimes consécutifs. Les résultats présentés mettent en évidence la partie importante des précurseurs d’arôme (jusqu’à 70% du potentiel aromatique total) et l’impact du millésime, mais surtout du terroir sur ces composés. Cette constatation nous a conduit à mettre au point une technique de vieillissement accéléré permettant une révélation rapide du potentiel aromatique lié, afin de pouvoir étudier rapidement son impact sensoriel. Cette étude est complétée par des analyses sensorielle dont les résultats mettent en évidence l’intérêt et l’importance de ce potentiel aromatique dans les caractéristiques olfactives finales du vins après son évolution optimale.

Health benefits of winemaking by-products: in vitro study of the phenolic profile and potential healthy properties

The wine sector plays a significant role in the international agri-food industry, with the winemaking process leading to the generation of considerable amounts of by-products. Among these by-products, grape pomace, is one of the most abundant resources, mainly finding application in the production of distillates, fertilizers, and animal feed.

Climate ethnography and wine environmental futures

Globalisation and climate change have radically transformed world wine production upsetting the established order of wine ecologies. Ecological risks and the future of traditional agricultural systems are widely debated in anthropology, but very little is understood of the particular challenges posed by climate change to viticulture which is seen by many as the canary in the coalmine of global agriculture. Moreover, wine as a globalised embedded commodity provides a particularly telling example for the study of climate change having already attracted early scientific attention. Studies of climate change in viticulture have focused primarily on the production of systematic models of adaptation and vulnerability, while the human and cultural factors, which are key to adaptation and sustainable futures, are largely missing. Climate experts have been unanimous in recognising the urgent need for a better understanding of the complex dynamics that shape how climate change is experienced and responded to by human systems. Yet this call has not yet been addressed. Climate ethnography, coined by the anthropologist Susan Crate (2011), aims to bridge this growing disjuncture between climate science and everyday life through the exploration of the social meaning of climate change. It seeks to investigate the confrontation of its social salience in different locations and under different environmental guises (Goodman 2018: 340). By understanding how wine producers make sense of the world (and the environment) and act in it, it proposes to focus on the co-production of interdisciplinary knowledge by identifying and foreshadowing problems (Goodman 2018: 342; Goodman & Marshall 2018). It seeks to offer an original, transformative and contrasted perspective to climate change scenarios by investigating human agency -individual or collective- in all its social, political and cultural diversity. An anthropological approach founded on detailed ethnographies of wine production is ideally placed to address economic, social and cultural disruptions caused by the emergence of these new environmental challenges. Indeed, the community of experts in environmental change have recently called for research that will encompass the human dimension and for more broad-based, integrated through interdisciplinarity, useful knowledge (Castree & al 2014). My paper seeks to engage with climate ethnography and discuss what it brings to the study of wine environmental futures while exploring the limitations of the anthropological environmental approach.

Valutazione dell’equilibrio vegeto-produttivo con metodiche di proximal sensing

Nel biennio 2008-2009, nell’ambito di un progetto multidisciplinare coordinato e finanziato dal Consorzio Tuscania, 4 vigneti in differenti zone della Toscana sono stati monitorati con strumenti di proximal sensing al fine di valutare la variabilità riscontrabile e ottenere delle indicazioni sulle risposte vegetative delle piante e quanti-qualitative delle produzioni.

From vineyard to bottle. Rationalizing grape compositional drivers of the expression of valpolicella aroma ‘terroir’

AIM: Valpolicella is a renowned Italian wine-producing region (Paronetto, 1981). Wines produced in its different sub-regions are anecdotally believed to be aromatically different, although there is no systematic study addressing the chemical bases of such diversity

Influence of the temperature of the prise de mousse on the effervescence and foam of Champagne and sparkling wines.

The persistence of effervescence and foam collar during a Champagne or sparkling wine tasting constitute one, among others, specific consumer preference for these products. Many different factors related to the product or to the tasting conditions might influence their behavior in the glass
