Variety description

10 August 2026

The fruits are oval-shaped with a light brown semi-paper shell that is easy to crack. The kernel has an intense red skin color, is not bitter, and retains its shade after drying. The tree is medium-sized or vigorous with a dense, spreading crown.

The variety matures in the second half of September. The trees are frost-hardy, adapted to the climate of Central Europe, but sensitive to late spring frosts due to early bud break. The variety shows moderate resistance to bacteriosis and anthracnose.
