That's fruit,..up to you, a little bunch doesn't hurt much, if you want a leader grow a little faster cut it off.

Fruit buds. If it were me, I'd leave them on so I'd get to sample some fruit this year. But that comes from a home gardener who likes experimenting with a variety of fruit in the backyard. If you are an orchardist and trying to maximize fruit production in future years, then follow the recommended pruning program. If you are a backyardy, let those clusters flower and fruit!

I am just starting grapes, too. That looks like a flower bud to me. Mine looked like that. I thought they were baby grapes and the next day, all buds opened to florets of tiny white yellow flowers. I hope when I go out tomorrow, they will have formed grapes. Have yours been through the flowering stage yet? If so, maybe yours really are baby grapes. What fun!

Thanks everyone! I think I may remove all but one bunch of fruit as there are quite a few of them! Thats exciting.
