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.

Withering of the ‘Moscato giallo’ grapes under covered space

For the purpose of producing predicate wines in northern part of Croatia, grapes are traditionally left on the vine unpicked. However, grapes on the vine are exposed to unfavorable environmental conditions that affect rapid rotting and attacked by birds. To eliminate the mentioned risks, the grapes can be picked and placed in a protected space (loft, greenhouse, etc.) suitable for drying. This study presents the results of research on withering grapes of the ‘Moscato giallo’ variety in two tretment: sun drying (under covered terrace) and drying in the shade (loft). The following quality parameters were monitored: mass of grapes, sugar concentration, content of total acids, pH, content of organic acids.

Influence of the vineyard’s surrounding vegetation on the phenolic potential of Vitis vinifera L. cv Tempranillo grapes

Wine industry has to develop new strategies to reduce the negative impact of global climate change in wine quality while trying to mitigate its own contribution to this climate change. The term “ecosystem services”, whose use has been recently increasing, refers to the benefits that human beings can obtain from the interactions between the different living beings that coexist in an environment or system. The management of biodiversity in the vineyard has a positive impact on this crop. It has recently been reported that practices such as plant cover can reduce the occurrence of pests, increase pollination of the vine, improve plant performance1 and affect the phenolic content of grapes.2

Prediction of the production kinetics of the main fermentative aromas in alcoholic fermentation

Fermentative aromas (especially esters and higher alcohols) highly impact the organoleptic profile of young and white wines. The production of these volatile compounds depends mainly on temperature and Yeast Available Nitrogen (YAN) content in the must. Available dynamic models predict the main reaction
(bioconversion of sugar into ethanol and CO2 production) but none of them considers the production kinetics of fermentative aroma compounds during the process of fermentation. We determined the production kinetics of the main esters and higher alcohols for different values of initial YAN content and temperature, using an innovative online monitoring Gas Chromatography device.

Evolution of acetaldehyde concentration during wine alcoholic fermentation: online monitoring for production balances

During alcoholic fermentation, acetaldehyde is the carbonyl compound quantitatively the most produced by yeasts after ethanol. The dynamics of acetaldehyde production can be divided into 3 phases. Early formation of this compound is observed during the lag phase at the beginning of fermentation before any detectable growth [1].
