Grape variety with sweet unripe berries

Here in iran we have a grape variety called"Tabarzeh" or “Ghoore shirin” which lacks sourness in its unripe berries unlike other grape varieties. You could pick it at verasion stage because its sweet :smile:
As you can see in pictures its not fully ripen but its consumable. Its a variety that exists both in red and green color like most other iranian varieties.
One of the best varieties for breeding programs in my opinion .
