Ugni Blanc is a French wine grape variety of medium ripening, widely grown in France and Italy. The bushes are medium-sized with medium to large leaves that can be slightly or moderately lobed, three- or five-lobed, sometimes with one basal tooth. The leaves have weak bristly-hairy undersides. The flowers are hermaphroditic, which promotes good pollination and crop formation. The clusters are medium-sized, conical in shape, often with one or two wings, and are dense to moderately dense. The berries are round, white, and medium-sized, covered with rare small dots, with a tough, thick, and transparent skin, and veins. The berry pulp is fleshy and juicy, giving the wine a harmonious taste. The variety's yield is 90-110 centners per hectare, which is a fairly high figure. Shoot ripening is good, and the variety is distinguished by relative drought resistance and medium resistance to fungal diseases. The minimum temperature at which the vine retains viability is about -22 to -25°C. The cluster weight varies from 100 to 400 grams, and the berry weight is from 1.5 to 3.5 grams. The rootstock for this variety is often 101-14, which promotes its adaptation and stability. Ugni Blanc is mainly used for the production of white table wines and brandy musts. Due to its characteristics, such as tough skin and fleshy pulp, it provides high-quality raw materials for winemaking. This variety is valued for its harmonious taste and versatility in use, making it a popular choice among winemakers in France and Italy.
