Wine Quality as a Part of Cultural Heritage Affected by Its Different Geographical Origins

Abstract

AbstractRegional products more and more often attract attention which as a result contributes to growing producer income and to the development of the whole region as well. Local products can be offered through innovation in restaurant services, enhanced production, farm visits and tastings related to tours of the vineyards. Regional products which can be awarded by Protected Designation of Origin (PDO) or Protected Geographic Indication (PGI) are those whose quality is connected with the places of their origin and local manufacturing methods. There is registered 15 415 ha of total vineyard area in Slovakia and production of quality varietal wines with the “Designation of Origin” or “Geographical Indication” has increased recently. In our work, the quality of Slovak wines within two selected varieties of different geographical origins was analyzed. Because in Slovakia there are six wine-growing regions, we tried to find some characteristics that differentiate the wines that originated from different wine-growing regions. Firstly, we used mainly chemical (FT-IR) analysis of 13 Sauvignon wines from three regions. Secondarily, Chardonnay variety (15 samples of wine) from five different growing regions was used and another chemical analysis based on GC–MS analysis was performed. By processing of results with statistical evaluation (PCA analysis), we detected differences among growing regions.
