in flavor ratings; 20.6 percent soluble solids.
Berry Size - Large, 4 to 5 grams.
Berry Texture - Non-slipskin; semi-crisp; skin thickness less than
many eastern table grapes.
Cluster Size - Medium-large, 200 to 250 grams average; similar weight
to Venus.

resistance to common fungal diseases but does require fungicide sprays for
successful production; small, soft seed traces observed occasionally but not
noticeable due to berry texture.
