“…All the selected viticultural surface areas had a southern exposition, and were planted on weakly mineral and moderate deep soil (regosol) [66] characterized by limestone gravels in a sandy matrix, rounded clasts, mainly cemented, containing low to moderate water reserve. This soil typology is appropriate for grapevine cultivation and high-quality productions [67].…”

“…The present study considered 7 grapevine varieties, both international (5 varieties), Merlot (M), Cabernet Sauvignon (CS), Cabernet Franc (CF), Chardonnay (CH), Sangiovese (S) and autochthonous (2 varieties), Aleatico (A) [67], and the native Grechetto di Orvieto (GR) [52]. These varieties are representative of the amphelographic base of the central Italy oenological products.…”

Developing adaptation strategies in Vitis vinifera, a crop sensitive to climate change, is crucial for resilience of traditional viticultural systems, especially in climate-vulnerable areas like the Mediterranean basin. A progressive warming is demonstrated to alter the geographical distribution of grapevine, reducing land capability for typical grapes and vine productions in most Southern European districts traditionally specialized in tree crops. Grapevine growth and reproduction under climate change require a continuous monitoring to adapt agronomic practices and strategies to global change. The present study illustrates an empirical approach grounded on a set of bio-physical indicators assessing the genotype-related response to climate variation. This approach was tested in Umbria, central Italy, to verify the response of some major international and local grapevine varieties to climate variation during a relatively long time interval (1995–2015). Long-term data for ripening time and berry quality collected in the study area were correlated to representative bioclimatic indices including Winkler, Huglin, and Cool night indicators. Results of this study highlighted the increase of air temperature (reflecting the inherent growth in thermal availability for maturation) and the alteration of precipitation patterns toward more intense precipitation. Climate variability exerted distinctive impacts on grapevine phenology depending on the related genotype. Empirical findings underline the usefulness of a permanent field monitoring of the relationship between selected climate variables and grape ripening with the aim to develop adaptive viticultural practices at farm’s scale.

“…These minor components, primarily phenolic and volatile compounds, are considered to contribute the most to the quality of the wine. All these substances are influenced by a multitude of factors, such as the genetic specificity of the grape variety, the environmental conditions, grape growing techniques, and—of utmost importance—the winemaking processes [ 1 , 5 ].…”

GC-FID/MS is a powerful technique used to analyze food and beverage aromas. Volatile organic compounds (VOCs) in grape berries play an important role in determining wine quality and are affected by many factors, such as climate and soil that mainly influence their relative concentrations. Wine aroma is generated by a complex mixture of compounds, and the sensory relevance of individual VOCs is far from elucidated. Herein, the VOC content (free and glycosylated) of Cannonau grape skin and juice and of Cannonau wine collected in different areas of Sardinia is explored. Wine sensory analysis was also carried out and the relationship between sensory attributes and VOCs was investigated. Although Cannonau grapes showed the same VOC fingerprint, great variability was identified between samples, although only the differences in 2-phenylethanol and benzyl alcohol concentration in the grape skins and benzyl alcohol and a terpenoid in grape juice were significantly different according to ANOVA. The correlation between VOC content and the sensory profile highlights the role played by 2-methyl-1-butanol and 2-phenylethanol in increasing wine sensory complexity.

“…The maturity of grapevine berries is the combination of optimal technological and phenolic maturity. If technological maturity is well documented and described as sugar and acidity balance (Jones and Davies, 2000;Ollat et al, 2002;Doshi et al, 2006;Castellarin et al, 2016), phenolic maturity depends on various secondary metabolites including tannins (Geny et al, 2003;Ali et al, 2010;Pantelić et al, 2016;De Santis et al, 2017). These phenolic compounds play an important role in red wine organoleptic characteristics, especially the mouthfeel properties like bitterness and astringency.…”

Aim: The importance of phenolic maturity (depending on tannins and anthocyans) of the grape is crucial at harvest and determines the final quality of wine. The work presented here aims to characterize the evolution of phenolic maturity of seeds for 3 varieties combining macroscopic analysis and biochemical analyzes of these tannins at phenological stages of interest.Methods and results: Using R software for macroscopic analyzes have been shown that the color varies dramatically (from green to dark brown) in the two months between the bunch closure and maturity. Biochemical analysis (HPLC measurement) shows that tannins in seeds are increasing from bunch closure to early veraison and decrease after this step until maturity.Conclusion: All together these results have shown that the color variation is correlated to the tannins content in the seeds.Significance of the study: Nowadays, no easy ways of prediction of phenolic maturity are known. The aim of this work is to use these results (usually considered independently) to have an knowledge of seed level of phenolic maturity necessary without biochemical analysis to establish a date of great harvest for the most favorable conditions for the extraction of tannins required for the organoleptic quality of a wine .The originality of this work is to use the combined visual seeds and its biochemical composition in tannins (correlation established by CPA). Forward, these results will help to develop a decision support tool based on simply system to acquiring seed image easily usable by winemakers.
