The Yermak blackcurrant variety is of medium ripening period and features a vigorous, dense bush with straight, light green shoots of medium length. The leaves are large, three-lobed with deep indentations, matte, leathery, and smooth, with a straight base and an acute angle between the lobes. The flowers are large and bright yellow, giving the plant a decorative appearance.
Yermak berries are large, round in shape, and almost black in color, with a dense skin of medium thickness. The average fruit weight is about 1.2 grams. The berries have a sour-sweet taste with a delicate aroma, confirmed by a tasting score of 4.3 points. They contain 3.1% acidity and 39 mg% of vitamin C, making them both nutritious and delicious.
The variety is distinguished by high yield, reaching 150 centners per hectare, as well as high frost resistance. Yermak is not demanding on soils but prefers regular watering and does not tolerate drought or excessive sunlight. This variety is not a hybrid of blackcurrant and loganberry, but rather an independent species belonging to the group of loganberry varieties.
