Belina Smudna ripens at the end of the third period, and starts its annual growth cycle medium early in the spring.
Yields are regular and high. It is susceptible to downy mildew and powdery mildew diseases and sensitive to low winter temperatures. It is not particularly susceptible to Botrytis cinerea (grey mould), except in rainy years due to the later ripening age. It gives the best results in elevated and warm positions. Due to high yields, cluster thinning is required. It can produce lighter wines with pronounced acidity, and it is also suitable for blending with other varieties.
