You are way welcome. Have fun with your grape. Some are really good and the grapes get bigger with proper care. But some are just bad.

Hopefully your's are the good ones.
We had a lot of wild grapes in the Central Valley of California. They were sweet but really really tiny. Pruning and care improve them greatly.
