Variety description
10 August 2026
The variety is a seedless table grape with cylindrical or oval berries, ranging in color from greenish-white to light green. The clusters are conical, of moderate density, with small or medium shoulders.
The plant is vigorous, belonging to the mid-season or mid-late maturity group. The fruits are distinguished by firm flesh and a sweet taste with a pronounced muscat undertone, which manifests upon full ripening.
When cultivated, the variety is sensitive to agrotechnical conditions, specifically being prone to rachis necrosis of the inflorescences and berry shatter. It requires the use of trellises, correct selection of rootstocks, and pruning to the fruiting cane, preferring regions with a warm climate.
