The study was conducted in a vineyard in the Buziaș-Silagiu area between 2023 and 2024. The vineyard has now reached full maturity after being established in stages between 2012 and 2018. The planting configuration consists of a row spacing of 2.2 meters and a vine spacing of 1 meter within rows, resulting in a planting density of 4,545 vines per hectare. The study aimed to evaluate how the grape varieties cultivated in the vineyard utilize the area's natural resources and how these factors influence the quality of both grape must and the resulting wine. Six grape varieties, which represent the largest cultivated areas within the vineyard, were analyzed: red wine varieties: Cabernet Sauvignon, Merlot, and Fetească Neagră; white wine varieties: Chardonnay and Fetească Albă; aromatic wine variety: Muscat Ottonel. Observations and analyses focused on the biochemical composition of the must, monitoring key parameters, assessing the evolution of the must during alcoholic fermentation, and evaluating the primary characteristics of the final wine. The Buziaș-Silagiu viticultural area has a long-established tradition and is well-suited for cultivating both white and red wines, as well as aromatic varieties. Despite the challenges posed by climate change, factors such as solar radiation, effective temperature accumulation, and precipitation levels remain relatively balanced, exerting a positive influence on vine growth and the overall quality of the wines produced.
