Grapes bunches too thin
I have a five year old seedless grape wine trained on trellis. I get about 30 bunches of grapes but many of them are too thin and small grapes. I wonder how to improve the fruit quality. This is my second year of as many bunches. PleSe see attached photos: Thank you for your help.

I am happy to help you with your grape issue. You mentioned photos but I don't see any attached. Will you please send them?
Thank you for your response.
I attached the photos.
I selected the photos and clicked done. Hope it works this time.
Thank you for your photos. I suspect the issue with your grapes is your pruning regimen. Have you pruned them at all? Here is an Extension article with very detailed information about care of grapevines, as well as instructions for pruning to increase yield and size: https://catalog.extension.oregonstate.edu/ec1639/html
I hope this is helpful. Good luck!
