Variety description
10 August 2026
The variety is a natural hybrid of Alba Imputotato and an unknown pollinator. The plant has medium to large, three- or five-lobed leaves. Bunches are medium-sized, weighing 150–200 g, cylindrical-conical. Berries are round, ranging from yellow-green to golden and amber in color.
The variety is mid-late, with harvest taking place in late September to early October. The plant tolerates drought well and is adapted to stony soils, but is sensitive to spring frosts. Susceptibility to downy mildew and grey mold is noted, as well as the need for proper training.
The grapes accumulate 20–25% sugars with an acidity of 5–8 g/l. Wines from this variety are noted for their freshness, body, and aging potential, often displaying aromas of citrus, apple, peach, as well as nutty, herbal, and mineral notes.
