Wine Quality Control Parameters and Effects of Regional Climate Variation on Sustainable Production

Abstract

According to the national and European Community legislation and the quality control regulations for wine, a series of analyses are carried out by government agencies on locally produced wines in Greece. The present study examines the analyses of dry white wines produced in the regions of Ioannina in the Epirus region and the Ionian Islands, correlating them with the climatic conditions of each region. The purpose of this correlation is to evaluate the effect of the local climate on the wines’ individual characteristics, as identified by the analyses. Another crucial objective of this study is the evaluation of the effects caused by the continual changes in climate on these characteristics, as determined by the analyses. Results indicate that the prevailing climatic conditions, in conjunction with climate change, can affect all the parameters evaluated in the analyses for the wines produced in the two regions under this study.

Electroanalysis of Oenological Products for Fingerprinting: a Brief Overview

“…Although numerous reports in the literature detail the metabolomic and chemometric profiling of wines and their identity according to highly relevant attributes such as geographical origin and grape variety, these technologies are still re-stricted in terms of application [20]. Owing to the high cost and infrastructural requirements of mass spectrometry and spectroscopic devices, these techniques are relegated to costly oenological products.…”

“…Regardless of the limitations in cost and portability, the analysis of wines by standard techniques significantly contributed to a better understanding of their chemical profiles and ways to classify their origin and quality according to the type and proportion of chemical constituents. Overall, wine authentication can be performed by assessing mineral content, volatile metabolites, phenolic constituents, amino acid profile, isotopic ratios, and NA analysis [20]. Indeed, several outreaches employed organic and mineral profiling with refined multivariate analysis and classification tools based on machine learning to establish objective thresholds for authenticity.…”

Precision agriculture for wine production: A machine learning approach to link weather conditions and wine quality

“…For such studies, most of them have focused on high extreme events could affect the growing of the plants, the quality of the wines as well as the definition of new areas where wine production can be conducted [1] , [39] , [16] . Similarly in other European countries, where wine is produced, as for instance Spain and Greece, a plethora of studies have been focusing on the urgence of defining new cultivations parameters and possible countermeasures to take into account the changing scenarios [18] , [20] , [29] . Soil pH changing, together with the rise in temperature can in fact lead to new cultivar cycles and the quality of the final product can dramatically be affected by such newly born scenarios.…”

Impacts of Climate Change in Baja California Winegrape Yield

“…Climatic and economic variables are well correlated with agricultural production, including viticulture, e.g., [21][22][23], such as temperature, precipitation, crop yield, and economic factors [9,15]. Some studies have used a climate-related model to predict agricultural yield and the impacts of some climatic variables on the suitability regions for grape planting [24][25][26], and others have focused on assessing the impact on grape growth and, consequently, the effect on the yield [24,[27][28][29][30][31][32][33][34][35].…”
