Enhancing table grape production: addressing challenges and opportunities for sustainability and quality improvement

Abstract

Table grapes, being consumed as fresh, raisins, and transformed products are among the most appreciated fruits worldwide. Its popularity is increasing also due to its organoleptic and nutritional qualities that meet the consumers’ interest in healthier foods. Recent data from International Organization of Vine and Wine (OIV) revealed that table grape production has doubled in the last twenty years, and varietal availability has increased thanks to the several breeding programs.

To maintain the socio-economic impact of this sector, new challenges need to be addressed. As for the entire agrifood sector, table grape production faces decreasing water availability, increasing temperatures, but also with fungal diseases, all consequences of climate change. Moreover, the need to align with new market trends is growing the interest of the researchers. In this context, new opportunities are emerging in the sector of ready-to-eat grapes with higher shelf-life, especially for major exporting countries such as Chile, Italy, and USA.  This area of the market is currently dominated with the production of raisins for snacks, while the possibility of allocating part of the grape production to fresh-cut markets is less explored. Strategies to improve postharvest performances, reduce fungi attacks and postharvest decay of existing or new table grapes varieties are essential in this latter context. 

Current literature and ongoing projects highlight the importance of developing strategies that combine breeding and sustainable management to cope with these new challenges and open new perspectives. Exploring the wide biodiversity and studying the physiological and molecular responses of different cultivars to identify involved genes is becoming fundamental to select new genotypes better adapted to the changed environment and consumers’ needs. Moreover, a faster improvement might be obtained by combining breeding with innovative and sustainable technologies in pre- and postharvest stages to increase resilience, quality, and shelf-life.

Spontaneous fermentation dynamics of indigenous yeast populations and their effect on the sensory properties of Riesling

Varietal Riesling aroma relies strongly on the formation and liberation of bound aroma compounds. Floral monoterpenes, green C6-alcohols, fruity C13-norisoprenoids and spicy volatile phenols are predominantly bound to disaccharides, which are produced and stored in the grape berry during berry maturation. Grape processing aims to extract maximum amount of the precursors from the berry skin to increase the potential for a strong varietal aroma in the wine. Subsequent yeast selection plays an important part in this process.

Effects of soil water content and environmental conditions on vine water status and gas exchange of Vitis vinifera L. cv. chardonnay

Vine water status has a significant influence on vineyard yield and berry composition (Williams and Matthews, 1990; Williams et al., 1994). It has been hypothesized that the response of plants to soil water deficits may be due to some sort of “root signal” (Davies and Zhang, 1991). This signal probably arises due to the roots sensing a reduction in soil water content or an increase in the mecanical impedance as the soil dries out.

Climate change impact study based on grapevine phenology modelling

In this work we present a joint model of calculation the budbreak and full bloom starting dates which considers the heat sums and allows reliable estimations for five white wine grape varieties

Variabilité spatiale du gel printanier dans le vignoble champenois : application au zonage climatique

In the Champagne vineyards, spring frosts are the cause of significant variations in the volume of the harvest which are very penalizing for the trade. This variability is reflected both in time (years without frost alternating with years with severe frosts) and in space. Certain sectors of the vineyard are in fact statistically more susceptible to frost than others, but each year no municipality can consider itself immune to this climatic accident. The objective of the study is precisely to analyze the spatial distribution of frost and to determine its main mechanisms, linked to the topography of the hillsides, their orientation but also to regional meteorological variables.

An online training tool for wine professionals around the world: from responsible service to a sustainable consumption of wine

Most consumers enjoy wine in moderation, however, there remains a minority that may develop risky drinking habits, potentially harming themselves and those around them. For the last fifteen years, a prime objective of the wine in moderation programme has been to educate and empower the wine sector and now for the first time, a central education tool has been developed, integrating the topic of moderate consumption horizontally in all wine activities. The entire wine value chain – from the producer to the salesperson to the restaurant service staff – can contribute to reduce harmful consumption and encourage responsible drinking patterns.
