HOLOVINI - Microbiomes at the interface of the vineyard and the cellar at the time of the agroecological transition

The wine industry is currently facing many challenges as it moves towards an agroecological transition. Grape berries, positioned at the interface of viticulture and winemaking, are critical sites where pathogens can develop and compromise both crop yield and quality.

Context and challenges

At harvest time, these berries become the main reservoir of microorganisms essential to the fermentation process. Environmental microbiomes significantly influence the berries microbiota acting as a link between semi-natural habitats, vineyards, cellars and the various parts of vine stocks, through dissemination by different vectors. Among the various vectors involved in this process, arthropods play a particularly important role in grape berry colonization.

Objectives

The HOLOVINI project aims to develop an innovative, comprehensive approach to understanding the role of environmental microbiomes and arthropods in grape berry colonization. The project focuses on two wine-producing regions and operates across multiple spatial scales. It employs robust, well-established research frameworks to integrate various landscapes and vineyard management practices and encourage the active participation of winegrowers. By identifying agroecological levers that promote biodiversity, HOLOVINI will help wine producers transition to sustainable practices without compromising environmental performance or wine quality.

HOLOVINI brings together a multidisciplinary team of experts in community and landscape ecology, microbiology, oenology, environmental mechanics, bioinformatics, and mathematical modeling.
