Variety description

10 August 2026

The tree grows with medium vigor at a young age, with growth slowing down as it matures. The crown has a characteristic pyramidal shape.

The fruits are distinguished by their high flavor qualities; they are juicy, sweet, and have a characteristic aroma. The skin of the fruits turns yellow upon ripening.

The variety is versatile and suitable both for fresh consumption and for various types of industrial processing, including the production of compotes, drying, and distillates. The tree's viability is good, although the variety requires standard maintenance for protection against diseases.
