The objective of this work was to investigate the effect of location on the composition and quality of wines from the viticultural zone PGI Drama. Grapes from two white (Sauvignon blanc, Assyrtiko) and three red varieties (Merlot, Cabernet Sauvignon, Agiorgitiko) were collected from nine locations within the zone during 2022. The vineyards span distances ranging from several hundred meters to 100 km, and their altitudes vary from 90 to nearly 820 m. Vinification was performed following the same protocol according to the type of wine. Wines were analyzed for quality parameters such as pH, total acidity, alcohol, and residual sugar content. In addition, elemental composition, phenolic content, antioxidant capacity, and sensory attributes of the wines were assessed. The obtained results suggested that besides the type of wine and variety, the location significantly affects the quality parameters of the wine. PCA analysis revealed that location is an important factor affecting the wine quality. The areas north and northwest proved more suitable for specific varieties, as they produce wines with more distinct organoleptic characteristics. The results provide insights into the behavior of international and native varieties in the face of global warming and assist in decisions concerning the most suitable plant material.
这项工作的目的是研究产地对葡萄种植地理标志保护产品（PGI）德拉马葡萄酒成分和品质的影响。2022年期间，从该产区的九个地点采集了两种白葡萄品种（长相思、阿斯蒂科）和三种红葡萄品种（梅洛、赤霞珠、阿吉奥吉提科）的葡萄。这些葡萄园的距离从几百米到100公里不等，海拔高度从90米到近820米不等。根据葡萄酒类型，按照相同的规程进行酿造。对葡萄酒的质量参数进行了分析，如pH值、总酸度、酒精含量和残糖含量。此外，还评估了葡萄酒的元素组成、酚类物质含量、抗氧化能力和感官特性。所得结果表明，除了葡萄酒类型和品种外，产地对葡萄酒的质量参数有显著影响。主成分分析（PCA）显示，产地是影响葡萄酒质量的一个重要因素。事实证明，北部和西北部地区更适合特定品种，因为它们生产的葡萄酒具有更独特的感官特征。这些结果为国际品种和本土品种在全球变暖面前的表现提供了见解，并有助于做出关于最合适种植材料的决策。
