The research was carried out over the 2020-2022 growing seasons and focused on specific local grape cultivars discovered in 2019 in the gardens or vineyards of amateur winegrowers in Alba County. Among these, 12 little-known or unknown local cultivars were studied, grouped based on grape quality and yield, and compared to well-known reference types widely distributed in the area. The local white wines were compared to the control 'Fetească regală', the red wine cultivars to 'Cabernet Sauvignon', and the fresh consumption cultivars to 'Chasselas dore'. The aim was to identifying the growth stages of local cultivars and identifies those that bud or bloom later, in order to mitigate risks associated with increasingly frequent climate variability. Additionally, the research focused on the main ampelographic characteristics, grape production quantity and quality, as well as disease and pest resistance, important indicators in the current context emphasizing cost and pollution reduction, and the production of healthier viticultural products. Most of the analysed cultivars displayed higher resilience against diseases and pests when compared to the control cultivars.
