The variety has a medium ripening period, occurring in early October. The plant is characterized by high and stable yields, as well as abundant lateral shoot formation, which requires additional work on thinning the bushes to prevent overcrowding.
Morphologically, the variety is represented by five-lobed deeply dissected leaves and medium to large loose bunches of cylindrical shape. The berries are rounded and acquire a yellow-green hue in the ripening phase.
The plant has high frost resistance and resistance to spring frosts due to late bud break. The variety is susceptible to oidium, therefore requiring placement in well-ventilated areas.
The grapes are used for the production of high-quality white wines, which are characterized by soft acidity and a rounded taste. The aromatic profile includes shades of apple, pear, citrus, white flowers, as well as notes of honey and spices.
