Variety description

10 August 2026

The variety was obtained by crossing the Pozsonyi Fehér and Csabagyöngye varieties. The bushes have medium vigor, and the shoots form few lateral shoots. The leaves are medium-sized, rounded, five-lobed, and deeply dissected.

The clusters are conical, often branched, loose or of medium density, with a weight from 135 to 300 g. The berries are medium-sized, rounded, light golden in color, and have juicy flesh and firm skin. The taste of the berries is characterized by harmony and a pronounced muscat aroma.

The variety has weak frost resistance (about -19°C) and low drought tolerance. The variety shows some resistance to downy mildew and gray mold, but is sensitive to powdery mildew. Wines made from it are distinguished by their lightness, low acidity, and notes of rose, citrus, and tropical fruits.
