Variety description

10 August 2026

The variety was obtained by crossing (Pinot gris × Fetească regală) × Riesling. Shoots possess weak to medium growth vigor. Leaves are medium-sized, pentagonal. Clusters and berries are small, the latter having a round shape and yellow-green color.

Full maturity occurs at the end of September. The variety's yield varies from very low to medium. The variety shows resistance to powdery mildew and flower drop; when using fungicides, it demonstrates medium resistance to downy mildew and gray mold.

Wine from this variety is distinguished by a yellow-green color, fruit-floral aroma, and fruit-spicy taste. Due to high sugar accumulation, the variety is especially suitable for the production of special wines.
