In the European Union, the change of wine grape variety for economic reasons in vineyards established under reconversion/ restructuring programs can be done after at least 10 years of vineyard exploitation. In the context of climate changes modifications in the microclimates of vine-growing areas are increasingly observed. Extreme climatic phenomena, with an impact on the harvest or the lifespan of grapevines, are becoming more and more aggressive, with quantifiable effects in the wine industry as well. We have carried out an analysis, on various aspects, of the behavior of the 'Cabernet Sauvignon' variety in the vine-growing areas of Romania. For comparison, the years 2018 and 2022 were analyzed, in the terms of cultivated areas and produced and marketed wines. Our analysis suggests that in the near future, in Romania, due to climate change, there will be vineyard areas where this variety will either no longer be cultivated, or it will be used only for the production of rosé wines or bulk red wines and oenological modelling according to consumption trends is neither economical nor justified.

This study provides an overview of the substantial changes in the structure of the wine grape assortment in Romania through the use of European funds allocated for vineyards reconversion/restructuring. Between 2007 and 2022, both new international varieties, which previously existed only in ampelographic collections, and old Romanian varieties, which are more adaptable to climate change and are increasingly appreciated by the wine drinking public, were introduced into the Romanian wine assortment. The study presents an update on the evolution of the areas cultivated with the most widespread wine grape varieties destinated for wines with protected designation of origin, protected geographical indication and varietally. On this basis, the quality level of the wines obtained during the 15 years studied was analyzed, based on the assessments made by the specialist tasting committees of the governmental Body which, on the basis of the traceability ensured by the producer, guarantees their origin and authenticity.
