Though both green and black grapes are available for sale, some people prefer to eat the black grapes since they get a cold after eating green grapes.
The black grapes are usually more expensive compared to the green grapes
In January when the grapes are first available for sale they cost Rs 160 per kg at some sellers.
The price of the grapes depends to some extent on the size of the grapes, if the grapes are larger in size the cost is higher.
