Application de l’Analyse du Cycle de Vie (ACV) à un domaine viticole

Résumé

L’Analyse du Cycle de Vie (ACV) est une méthode multicritère qui permet de quantifier les impacts environnementaux associés à l’activité d’une entreprise sur l’ensemble de son cycle de vie et de guider les choix en vue de l’écoconception. Elle inclut par exemple des indicateurs liés aux émissions de gaz à effet de serre et à la capture de carbone, aux émissions de particules fines, à la consommation d’énergie ou à la pollution des eaux. Appliquée au domaine viticole du Château de l’Eclair, elle permet de renseigner sur les sources de pollutions les plus importantes de l’entreprise, mais aussi plus généralement de la filière. Les résultats permettent de mettre en évidence le poids important de la fabrication des bouteilles en verre dans le bilan environnemental du vin sur un grand nombre d’indicateurs, dont l’empreinte carbone. Toutefois, la mise en place d’un enherbement de l’inter-rang et le retour au sol des sarments à la vigne, permet d’après la modélisation, de séquestrer environ un quart des émissions de gaz à effet de serre de la production de vin. Les résultats montrent également le gain environnemental du passage en agriculture biologique sur l’indicateur écotoxicité de l’eau douce.

Application of Life Cycle Assessment (LCA) method to a French winery

Life Cycle Assessment (LCA) is a multi-criteria method for quantifying the environmental impacts associated with a company’s activity, and for guiding choices with a view to eco-design. It includes, for example, indicators relating to greenhouse gas emissions and carbon storage, fine particle emissions, energy consumption and water pollution. Applied to a winery, it provides information on the most significant sources of pollution for the company, but also more generally for the industry. The results show that the manufacture of glass bottles contributes significantly to the environmental impact of wine on many indicators, including the carbon footprint. However, the introduction of inter-row grassing and the return to the soil of vine shoots, according to the model, sequesters around a quarter of the greenhouse gas emissions from wine production. The results also show the environmental benefits of switching to organic farming in terms of freshwater ecotoxicity.

Evolution of the metabolic profile of grapes in a context of climate change

In the current context of global climate change, anticipating the evolution of the oenological potential of emblematic grape varieties of regions such as Burgundy and Champagne is a guarantee of the sustainability of a sector which has considerable economic weight. however, if various models of climate change cast doubt on the sustainability of these grape varieties in these regions, appellation decrees, as well as consumer expectations, do not allow or consider the use of alternative grape varieties. In addition, control/compensation methods such as irrigation are also not permitted.

Three new Apulian seedless varieties available for the table grape supply chain

The table grape industry in Europe is undergoing significant changes. For instance, in Italy, the national register of vine varieties was established in 1969, and since then, many varieties of table grapes have been registered. In the first thirty years, from 1969 to 1999, 62 seeded and 24 seedless varieties were registered. In the subsequent period, from 2000 to the present day, 23 seeded varieties and 99 seedless varieties were registered.

Viticultural landscape: history of a challenging coexistence between grapevines and humans 

Vitis vinifera is the most grown grapevine species, which originated about 6 million years ago in the trans-caucasian area as the ancestral (wild) type v. Vinifera spp. Sylvestris. On the other hand, the human being (homo sapiens) is much younger since he originated about 300.000 years ago in north africa.

Validation of a method for the determination of volatile compounds in in spirituous beverages using contained ethanol as a reference substance

The results of experimental studies of the method based on the usage of ethyl alcohol as an internal standard for the direct determination of volatile compounds in wines and others alcohol contained products are presented. The method was validated in terms of precision, accuracy, limits of detection and quantification (lod and loq), linearity, and robustness.

Generation of radicals in wine by cavitation and study of their interaction with metals, phenols and carboxylic acids

High-power ultrasounds have been related to an accelerated aging of wines, an effect that has been associated to the formation of radical species caused by the cavitation phenomenon [1]. This phenomenon consists of the formation of bubbles in the liquid medium that, when they collapse, cause high-pressure hot spots and temperatures of up to 4800 k [2], notably increasing the reactivity in the medium.
