Caractérisation du terroir en Espagne : méthodologie de l’évaluation et de la validation

Wine is one of the most consumed and appreciated beverages in the world. Due to the growing attention paid to consumer health, there is a continuous search for sustainable alternatives to common additives (such as sulfur dioxide) used to preserve wine. An example is represented by chitosan, the main derivative of chitin, approved for the treatment of must and wine since 2009 by the “international organization of vine and wine” (OIV/OENO 338a/2009) and by the european commission (EC Reg. No. 606/2009).

Methyl-jasmonate (MeJA) induces the production of at least 25 compounds with sesquiterpene- like mass spectra in ‘Cabernet sauvignon’. Tost effective concentration of MeJA in stimulating the production of sesquiterpenes was found to be 500 µM if added when the cell suspensions had a PCV of 35 %, and 1000 if added when the cell suspensions had a PCV of 70 %.

The main aim of WiSSaTech project (PRIN P2022LXY3A), supported by Italian Ministero dell’Università e della Ricerca and NextGenerationEU program, is to investigate eco-friendly and safe alternatives to sulphur dioxide (SO2) in wine production.

The agro-ecological transition in winegrowing can benefit from the environmental assessment of practices to inform producers’ technical choices. life cycle assessment (lca) evaluates the environmental impact of a product over its entire life cycle. this paper takes a look at the tools available for the detailed assessment and eco-design of winegrowing practices, their uses and developments in the vitarbae research project (2023-2026). this project aims to establish and equip support and training courses for the agroecological transition in viticulture and fruit arboriculture.

The wine industry is increasingly focused on carbon accounting due to consumer’s demand and the industry’s goal of reducing carbon emissions.
