Grape vine in Ottawa

[Jean-Louis]

Hi. I hope this is the correct forum for this question.
I have four concord grape vines that are well established and have been providing grapes for several years, except for one, that has not yielded fruit for the past two years. The problem with this vine is that it produces leaves in the Spring like the others, but inside the new leaf clusters, there are grape buds already (see photo). I don't know why this is happening, but my thoughts are that this is too early, and when the buds flower, they do not get pollinated.
I would appreciate any help.

You want buds like that. Grapes are self pollinating so they are indeed getting pollinated. They might be freezing if it is an earlier grape than the others.

Thanks Grapeman. However, I am still left with this vine that has not produced grapes for the last 2 years. Maybe it was just resting and will bear fruit this year.

Maybe it tried to produce grapes but if it got a bad blackrot infection you would have lost all the grapes.

Maybe some weird mutation? It's not very likely but still possible!
