Using climate services to project grapevine varietal adequation under climate change – application to cv. Tempranillo in the Douro wine region

Abstract

Vine growth circumstances are becoming warmer and drier because of climate change. Higher temperatures advance ripening to a point in the season less conducive to the production of fine wine, while drought reduces yields (Van Leeuwen et al., 2019). Several wine-producing regions around the world have already recognized threats to their viticultural viability (Santos et al., 2020). An economical and cost-effective strategy for adaptation is the employment of late-ripening, drought-resistant plant material (varieties, clones, and rootstocks). Ancient varieties’ wide genetic pool becomes a significant resource for the production of premium wines with sustainable yields. An end-to-end wine pilot climate service has been developed in the MED-GOLD project. The MED-GOLD wine climate service offered data at various time scales addressing specific concerns of the wine industry, e.g., suitability of varieties for future climates (Dell’Aquila et al., 2023). In this work, we use the MED-GOLD climate service to evaluate the future suitability of cv. Tinta Roriz (syn. Tempranillo) for the Douro wine region of Portugal. Comparison of high-resolution (1 km2) maps of areas with adequate growing season average temperature between the past and two periods until the end of the century, shows that variety is becoming unsuitable for quality wine in more than 90% of the present-day wine region area. The same approach can be used to identify which varieties show better adaptive profile and inform farmers’ choices for the future.

Impact of climate on berry weight dynamics of a wide range of Vitis vinifera cultivars 

In order to study the impact of climate change on Bordeaux grape varieties and to assess the behavior of candidate grape varieties potentially better adapted to the new climatic conditions, an experimental vineyard composed of 52 grape varieties was planted in 2009 at the INRAE Bordeaux Aquitaine center[1]. Among the many parameters studied since 2012, berry weight for each variety was measured weekly from mid-veraison to maturity, with four independent replicates. The kinetics obtained allowed to study berry growth, a key parameter in grape composition and yield.

Water and nutritional savings shape non-structural carbohydrates in grapevine (Vitis vinifera L.) cuttings

Global changes and sustainability challenge researchers in saving water and nutrients. The response of woody crops, which can be forced at facing more drought events during their life, is particularly important. Vitis vinifera can be an important model for its relevance in countries subjected to climate changes and its breeding, requiring cuttings plantation and strong pruning.

Applicability of grape native yeasts to enhance regional wine typicity

The universalization in wine production has been restricting the imprint of terroir in regional wines, resulting in loss of typicity. Microbes are the main driving force in wine production, conducting fermentation and originating a myriad of metabolites that underly wine aroma. Grape berries harbor an ecological niche composed of filamentous fungi, yeasts and bacteria, which are influenced by the ripening stage, cultivar and region. The research project GrapeMicrobiota gathers a consortium from University of Zaragoza, University of Minho and University of Tours and aims at the isolation of native yeast strains from berries of the wine region Douro, UNESCO World Heritage, towards the production of wines that stand out in the market for their authenticity and for reflecting their region of origin in their aroma.

Reduction of the height of the canopy in fruit set and in pea size: vegetative, productive and maturation effects, in cv. Verdejo

Global warming is accelerating the technological ripening of the grape, with a loss of acidity, which requires that vineyard management can delay ripening to avoid it. The source-sink relation is essential for grape ripening, since it affects the distribution of photosynthates and substances derived from plant metabolism. A work is proposed to know the response of the vineyard to the drastic reduction of the foliar surface by trim down the shoots in cv.

Advancing grapevine science through genomic research

The seminar will examine the complexities and prospects of genomic research on Vitis species, characterize by exceptionally high heterozygosity and common interspecific gene flow. The seminar will showcase case studies highlighting the critical role of diploid genome references in grape research, specifically in areas such as aroma development, disease resistance, and domestication traits. It will also address the emerging focus on pangenomes within the Vitis genus, particularly in the context of genetic studies on naturally interbreeding populations.
