The bush has medium vigor. Leaves are medium or large in size, rounded, 5–7-lobed. The cluster is medium-sized, cylindrical, medium density, often with two small "wings". Berries are medium or small in size, rounded, green-yellow in color.
Harvesting takes place in the second half of September — the first ten days of October. The variety possesses relative resistance to winter and spring frosts, while resistance to fungal diseases, especially grey mold, is low.
Yield is stable, medium or medium-high. Wines in style are close to Riesling, possessing a full harmonious taste with pronounced acidity and notes of apple, pear, apricot, peach, citrus, linden, and quince.
