Relationship between grape berry size and oenological characteristics
Abstract
The composition and oenological characteristics of grape berries can be influenced by various factors, including their size. Therefore, several studies were conducted in the Mișca vineyards between 2019 and 2022, focusing on Merlot, Cabernet Sauvignon and Feteasca Neagră varieties. The studies were carried out considering the varieties, with Simple Guyot training system, and by cluster thinning (at a rate of 40%) or without thinning, during the veraison stage. Random selection of 25 vines from each variety, in each experimental plot was performed. Samples were collected on the harvest day, with maturity determined based on sugar content, titratable acidity and pH of the berry juice. Laboratory analyses included measurements of berry weight, sugar content, total acidity, pH and anthocyanins potential. Statistical analysis was employed to assess differences between means, while the Pearson correlation coefficient was used for further analysis. The results revealed differences between varieties regarding berry weight, sugar content and anthocyanin potential. Furthermore, the berry quality was influenced by the temperature and precipitation of each year. Although thinning of clusters did not significantly influence berry weight, it did affect anthocyanins and sugar content depending on the favourability of the growing season. The study highlighted the complex interaction among vineyard management practices, climatic conditions and grape variety in shaping the characteristics of grape berries.
