The variety is the result of crossing Müller-Thurgau with a hybrid of Madeleine Angevine and Early Calabrese. Vines are characterized by medium to vigorous growth and require fertile soils with good moisture availability.
Leaves are medium-large, five-lobed, smooth, and shiny. The cluster is medium-sized and loose, which reduces the risk of Botrytis cinerea infection. Berries are medium, yellow-green in color, acquiring an amber hue upon full ripening.
The variety possesses low frost resistance and is sensitive to spring frosts, as well as being susceptible to downy mildew and powdery mildew. At the same time, it is distinguished by a fairly high yield.
Wines from this grape have a neutral profile, low acidity, and a delicate floral bouquet with notes of apple, pear, and citrus. The variety is valued for its ability to ripen in cool climates.
