Variety description

10 August 2026

The tree has medium vigor and forms an upright crown of medium density. The variety is compatible with quince rootstocks, is suitable for all traditional pear-growing regions, and requires cross-pollination.

Fruits are blunt-conical in shape, weighing 170–200 g, and have smooth, bright yellow skin, sometimes with a slight blush. Upon ripening, the flesh becomes buttery, tender, and sweet in taste with a light acidity and pronounced aroma. Harvesting begins in the first ten days of August.
