The variety is mid-season; the harvest time occurs 3–5 weeks after the Flame Seedless variety. The vines have medium to strong vigor and are characterized by high fruitfulness.
The berries range in size from large to very large, with a diameter of 19–22 mm. The flesh is firm and crunchy, and the sugar content is 19–22° Brix. The variety has a very good ability for long-term storage, maintaining product quality after 6 weeks of storage.
The origin of the variety is linked to a controlled hybridization program. Data on resistance to fungal diseases are absent in open publications.
