Study of the adaptability of ‘Korinthiaki Staphis’ (Vitis vinifera L.) at different altitudes as a strategy for mitigating the effects of climate change in Greece

The aim of the study was to determine how different altitudes affect the qualitative and quantitative characteristics of the berries of grape cultivar ‘Korinthiaki Staphis’ (Vitis vinifera L.), as well as of the dried product (raisins). Climate change presents new challenges to sustainable viticulture, particularly in mediterranean countries like Greece, where its effects are even more severe.
Cultivating grapevines at higher altitudes appears to be a potential solution.
The phenolic potential of the grape skins of the cultivar were assessed, under the influence of different altitudes in the region of Aigio, Peloponnese.
Grape samples were collected from three vineyards at altitudes of 250, 500, and 650 m.
During ripening, the following determinations took place: mechanical properties of grapes and berries, content of the must (TSS, pH, and acidity). In addition, the various total phenolic compounds of grape skins were quantified with the use of spectrophotometry, while the individual anthocyanins and the content of the must in individual sugars, acids were determined by HPLC. The results indicated that there is correlation between different altitudes and the concentration of different qualitative characteristics.
More specifically, higher altitudes led to an increase in total acidity and individual acids, while grapes from lower altitudes showed increased concentrations of total soluble solids, as well as total and individual anthocyanins.
