Variety description
10 August 2026
The variety is mid-early or mid-season, ripening 1–2 weeks earlier than the Thompson Seedless variety. The plant has medium to moderately low vigor and very high fertility.
Berries have a size of 19–24 mm, an oval to broad-ellipsoid shape, and firm, crisp flesh. Sugar content is 18–20º Brix. The variety is characterized by high keeping quality, maintaining its commercial appearance for up to 6 or more weeks after harvest.
The grapes demonstrate high adaptability to Mediterranean-type climatic conditions with hot, dry summers.
