Variety description

10 August 2026

The variety is a complex hybrid bred by Professor Vilém Kraus. Shoots have weak to medium vigor. The variety is characterized by a late ripening period, with full berry maturity reached in mid-October.

The leaves of the variety are medium-sized and pentagonal in shape. Clusters are small and compact; berries are also small, round, and yellow-green in color. Yield is low to medium. The variety is resistant to flower drop; with fungicide protection, it exhibits resistance to downy mildew and powdery mildew, and medium resistance to grey mold.

The grapes are intended for the production of wines characterized by harmony and expressive aromatics with herbal, fruity, spicy, or "bread" notes. Due to its ability to accumulate significant amounts of sugar, the variety is suitable for the production of special wines, including late-harvest and botrytized wines.
