The objective of this study was to evaluate the quality aspects of grapes harvested prior to the commencement of the 2023 winemaking campaign at Pietroasa Winery. Grape samples from eight distinct varieties - Busuioacă de Bohotin, Tămâioasă Românească, Riesling Italian, Alb Aromat, Fetească Regală, Fetească Neagră, Merlot, and Cabernet Sauvignon - were collected during the harvest season at Pietroasa. This paper details the analysis of key quality indicators, including fruit weight, shape index (SI), firmness, total soluble solids (Brix), total titratable acidity (TTA), pH, dry matter content (DM), total polyphenols content (TPC), and antioxidant activity (AA), all of which are critical to assessing wine quality. It synthesizes current research on grape quality, highlighting the significant antioxidant capacity attributed to polyphenol content and suggesting avenues for future research on wine production at Pietroasa Winery. In conclusion, the study reaffirms the suitability of the Pietroasa region for vinification, attributed to its terroir which ensures the production of grapes of high quality, resulting in wines with desirable and distinctive aromatic profiles.
