The study was conducted between 2022 and 2023 with the aim of tracing specific elements of chemical composition from
grapes to wine, focusing particularly on the 'Fetească Neagră' and 'Pinot Noir' varieties. These grape varieties were
cultivated in five distinct wine-growing regions across Romania. A significant part of the grape's substances is
proportionally transferred into the wine, blending with other beneficial compounds resulting from the conversion of grape
must into wine. The correlation between the chemical composition of wine and its derivation from the chemical
composition of the grape is a critical factor in forecasting wine quality. The chemical composition of the grapes was
assessed at full maturity, and included the following elements: water, proteins, total lipids, ash, dietary fibers, and sugars.
The corresponding components were subsequently traced within the wine. The examination took place subsequent to the
stabilization of the wines, carried out in anticipation of bottling and consumption. The determination of both grape and
wine samples' chemical composition adhered to specific standards validated by the Association of Analytical Chemists.
