The variety is an interspecific hybrid obtained by crossing Zala Gyöngye and the hybrid Gloria Hungariae x Erzsébet Királyné Emléke. The vine is characterized by vigorous shoot growth and good cane maturation. The early-mid ripening period is 120–130 days; the harvest is usually ready by mid-September.
The clusters are medium to large in size, reaching a weight of 400–500 g, and are characterized by a medium-loose structure. The berries, weighing 2–3 g, range in color from greenish-white to yellow, and have juicy flesh and firm skin. The taste is balanced and sweet, with a pronounced muscat aroma.
The plant has high resistance to downy mildew and other fungal diseases, which allows the variety to be used in organic viticulture. Winter hardiness is moderate, and excessive crop load reduces frost resistance. The fruits are well-suited for transportation and can be stored on the vine for a long time until the onset of frost.
The variety is intended primarily for fresh consumption, but is also used for juice production and in winemaking for blending to improve aromatic characteristics.
