STUDY OF THE BEHAVIOR OF SOME WHITE WINE VARIETIES GROWN IN THE BLAJ WINE-GROWING CENTER

Rezumat

The study analyses the behaviour of four white wine grape varieties —Italian Riesling, Fetească Regală, Muscat-Ottonel, and Sauvignon —grown in the Blaj-Cenade wine-growing area. The research was conducted between 2019 and 2021 and consisted of assessing the climatic framework and the productive and qualitative potential of these varieties in the context of climate change. The year 2019 was hot and dry, with positive temperature deviations and low precipitation; 2020 was close to normal in terms of temperature, with high rainfall between August and October; and 2021 was normal in terms of temperature, with moderate precipitation. Climate indicators and wine production quality indicate that the Blaj-Cenade wine-growing centre is suitable for growing white varieties for high-quality wines. The study provides useful data for the sustainable management of vineyards in the context of climate change.
