I just looked at the few grapevines we have in the yard. The Niagara grapes which were the size of a pinhead  just a few weeks ago are now much bigger and I can hardly wait. Unfortunately due our trip to Colorado, weeds and shrubbery and too much rain has started to take its toll. We’ve removed the dark, shriveled grapes. Also, trimmed and weeded and hopefully air circulation is better now. I can almost taste the luscious grapes now. The two Dornfelder vines we purchase in May are growing and taking off. Hopefully, they will become strong enough to make it through next winter. Are you growing grapes in a home garden? What variety did you plant?
