Is this in use:

No.

 

[B45]

No.

Could you change it to something correct?

"A bunch of grapes" is possible.

A vineyard might find that it had a batch (part of a crop) of grapes which went off or were unusable in some way. I have no idea if the term is used in a technical way in viniculture. However, the usual term, as bhaisahab said, is "a bunch of grapes". Like this one.
