Fetiyska white is a technical grape variety bred in Hungary and widely common in the countries of the Black Sea basin, such as Romania, Bulgaria, and Hungary. This variety belongs to early-ripening white technical varieties, with berry ripening usually occurring in mid-September. Bushes have medium growth vigor, and the vine matures well, ensuring stable yields. Leaves of Fetiyska white are deeply lobed, five-lobed, with a widely open arrow-shaped petiole cleft and a smooth surface. Shoots and petioles have a light wine-red tint, while leaves turn yellow in autumn.
Bunches of this variety are of medium size, cylindrical-conical in shape, of medium density or dense, sometimes with wings. Berries are round, of medium size, about 14 mm in diameter, greenish-yellow in color with a bluish bloom on the sun-exposed side and a slight tan. The skin is thin but sufficiently strong and translucent. The pulp is juicy, with a harmonious taste, and the juice is colorless. There are 3-4 seeds in the berries. The average bunch weight is about 93 grams, and the weight of 100 berries varies from 115 to 150 grams.
Fetiyska white is used mainly for the production of white table wines, sparkling wine materials, and juices. The variety is characterized by good adaptation to various soil conditions, including brown earth-mull loamy and chernozem soils with a light mechanical composition. Thanks to the deep root system, grapes tolerate drought better than other varieties. However, the variety is sensitive to some diseases, such as mildew, powdery mildew, and grey rot, especially in rainy autumn, and is also susceptible to damage by spider mites in dry and hot weather. Frost resistance of Fetiyska white is average, with some vulnerability to spring frosts due to early bud break. For bush formation, a multi-branched fan or trunk form is recommended; however, the variety is unsuitable for mechanized harvest.
