Future projections for chilling and heat forcing for European vineyards

Il n’existe presque pas d’études qui caractérisent l’effet du climat viticole sur la typicité des vins en considérant les différents types de climats à l’échelle mondiale. Cette étude fait partie d’un projet CYTED de zonage vitivinicole. L’objectif a été de caractériser l’effet du climat viticole sur la typicité des vins sur une macro région viticole du monde.

The ability of grapevine cultivars and rootstocks to cope with and adapt to recurring water constraints is the focus of this study. The contribution of intrinsic (epigenetic) and extrinsic (rootzone microbial community) factors to water stress resilience will be discussed. The study was conducted in a validated model vineyard where three scion cultivars (Pinotage, Shiraz, and Cabernet Sauvignon) on two rootstocks (Richter 110 and USVIT8-7) grow under recurring seasonal water constraint (and control) scenarios since planting (in 2020). Comprehensive profiling of the site, soil, atmospheric conditions, plants, and their physiological responses provide contextual data for the analyses conducted.

The production of Port Wine requires the addition of grape spirit to stop the fermentation, ensuring the desired sweetness

Evidence indicates that climate change affects the environment, human health, and well-being via drought, increasing greenhouse effect, and climatic catastrophes. As the wine sector is also negatively affected by climate change, the role of climate change mitigation and adaptation policies is important in wine production. One example of an adaptation policy is the implementation of grapevine genetics (duchene, 2016), while organic farming may be used as an approach to mitigate the consequences of climate change (vinci et al., 2022). To this end, the european commission’s objective is to reach the european green deal target of at least 25% of the european union’s agricultural land under organic farming by 2030.

Lambrusco is a commercially successful sparkling red and rosé wine. With 13.06 million litres sold in 2021 was the second best-selling Italian wine after Chianti. According to National Catalogue of Vine Varieties there are thirteen Lambrusco Varieties with which to date are produced seven PDO wines. Among these, “Lambrusco Salamino di Santa Croce”, “Lambrusco Grasparossa di Castelvetro” and “Lambrusco di Sorbara” are the only ones that can be considered mono-varietal appellations, all located in Modena area. The PDOs contemplate the possibility of producing wines by secondary fermentation either in tank (Charmat method), or in bottle (Classico method). Sur lie is a third method commonly employed for Lambrusco, similar to the Classico method, from which differs for the absence of disgorgement.
