The variety is the result of breeding that began in 1994. Leaves are medium-sized, pentagonal. Clusters are from medium to large size, from medium-density to dense. Berries are medium, round, yellow in color, acquiring a golden hue upon full ripening.
The variety is mid-early, ripening in the period from late September to the second half of October. Yield varies from low to medium-high. The grapes are resistant to downy mildew, powdery mildew, gray mold, and flower shedding, and do not require complex crop load adjustment.
The resulting wine has a yellow-green color and a delicate aromatic profile. Taste and aromatic characteristics include fruity and floral notes, often with pronounced Muscat tones and fresh acidity.
