Variety description

10 August 2026

The vines possess medium vigor and are prone to lateral shoot formation. Leaves are medium-sized, rounded, five-lobed, and medium to deeply dissected. Clusters are of medium size, weighing 150–300 g, conical in shape, often branched and moderately loose. Berries are medium, rounded, covered with a firm skin, and the flesh is juicy.

The variety possesses sufficient resistance to downy mildew and gray mold, but is susceptible to powdery mildew. Frost resistance is rated as low, down to -19 °C; poor drought tolerance is also noted. The plant prefers sites with good heat accumulation, such as southern slopes.

Wines from this variety are distinguished by intense floral-citrus muscat tones. They are characterized as light and fresh, intended for consumption at a young age due to the rapid loss of acidity during aging. The variety is also used for the production of grape brandy.
