Sažetak

The research was conducted in the Kutjevo vineyard at the locations: Škomić, Vetovo, Hrnjevac, Vinkomir and Oljasi, on the Graševina variety during 2020. Vetovo, Hrnjevac and Vinkomir are located at altitudes above 300 meters above sea level, while Škomić and Oljasi are at about 200 meters above sea level on more fertile soils. The goal of the research was to show the influence of a particular location on the dynamics of grape ripening and the quality of must through the basic parameters that are most often used today to determine the technological maturity of grapes. Sampling was done during the first two weeks of September due to the climatic conditions and accelerated ripening of the grapes. The experiment was set up in a randomized block arrangement with three repetitions. Physical and chemical analyzes of the samples were performed on the WineScan device in the Kutjeva d.d. laboratory. Differences in sugar content and total acidity were determined. Graševina must from Škomić had the lowest sugar content during the entire maturation period and the highest total acidity. Differences in pH value between positions were not determined.
