Sauvignon Blanc, also known as Совиньон, is a French technical grape variety widely distributed in various countries, including France, Austria, Romania, Bulgaria, Hungary, the USA, Argentina, and Australia. This variety belongs to the Western European eco-geographical group and is characterized by medium-sized leaves with deep lobation and a funnel shape. Bunches of Sauvignon Blanc can be cylindrical, of medium or small size, with a dense berry arrangement. Berries are round, greenish-white, and acquire a yellowish-pink hue when ripening in the sun. The pulp is juicy, with a harmonious taste and a characteristic aroma with a slight aubergine aftertaste.
Sauvignon Blanc is a medium-term ripening variety with a vegetative period of about 139 days, and differs in medium or low yield. It adapts well to cool regions and is capable of withstanding frosts down to -21 degrees. Bushes of the variety are vigorous, with a spreading form; leaves have wavy edges and a yellowish tint. Bunches are of medium size, cylindrical-conical in shape, with a long herbaceous stalk. Berries have medium skin density and contain 2-4 seeds. The variety is relatively resistant to downy mildew, but is susceptible to powdery mildew and gray mold under unfavorable weather conditions. For successful cultivation, it is recommended to plant grapes on light sandy soils with good drainage and ensure systematic application of organic and mineral fertilizers.
Sauvignon Blanc is widely used in winemaking for the production of high-quality white table wines, sparkling wine materials, and juices. Technical indicators of the variety include a high juice yield — about 89%, with must sugar content of 18-22 g/100 ml and acidity of about 7.5 g/l. Due to its taste qualities and aroma, this variety is valued both for industrial production and for consumption in fresh form.
