A vineyard with diverse climatic conditions along the seaside affects the growth and development of the vines and grapes (Vitis vinifera L.). Therefore, knowledge about these factors is crucial for determining how viticultural practices need to be adapted to improve the grape yield and quality. The submitted study aimed to evaluate the effect of the terroir between the mountains and sea on the berry composition, grape ripening, and produced wines’ characteristics. In the vineyard located in Aghbash Village, within the Samur-Devechi lowland at the foothills of the Greater Caucasus Mountains and on the coast of Caspian Sea, several grape cultivars incurred assessment during 2023. The Saperavi, Merlot, Madrasa, Muscat, Chardonnay, Cabernet Sauvignon, and Khindogni grape cultivars bore scrutiny for titratable acidity, pH, and sugar concentration. Correspondingly, wines produced from these grape cultivars also underwent analysis for ethyl alcohol content, residual sugar, titratable acidity, volatile acidity, extract content, and total and free sulfur dioxide concentrations as per standard procedures. The grape cultivars Muscat and Cabernet Sauvignon had lower sugar concentrations (21.2 g/100 cm³), and cultivars Muscat and Cabernet Sauvignon emerged with lower titratable acidity (5.0 g/L) and higher titratable acidity (6.4 g/L), respectively. However, cultivar Madrasa exhibited a higher sugar concentration.
