Meanwhile, the summer royal black seedless grapes the company has offered for a couple of years steadily are gaining popularity, he said.
At Pandol Bros., some of the stronger varieties are the black autumn royal and summer royal and the red crimsons and flames, Kieva said. The scarlet royals also are growing in volume.
Of the 13 varieties Castle Rock offers, all are seedless except red globes and the green calmeria variety, Llano said.
Many of the red globes are exported.
“We still have (seeded grapes) because there are still niche markets for those varieties,” he said.
