We have a 3-yr old vine which produced black grapes until this year when the grapes are green. I pruned it at the wrong time two years ago and had virtually no fruit the following summer. However, this year I pruned it at the proper time and have a bumper crop but the grapes are no longer black. Any ideas why?



was it on a grafted rootstock? it may be that you pruned out the black variety and now you have the rootstock variety.

No not on a grafted rootstock. We're a bit baffled really. Thanks for your thoughts anyway.

Maybe you have to wait a bit longer for them to go black Peemick. Our Pinot Noire was green until about a few days ago. In response to more sunshine they have gone over to colour change very fast. As far as I understand it all black grapes start out green. The weather has been very mixed in different places. We had a drought+heatwave, others have had grey skies,coolness and rain. Pinot Noire may be turning black now but will not be sweet until October, the starlings always know that!

Thanks for all your responses and good to know I'm not the only one! Will wait a bit longer & see if they change colour as we've got plenty of sunshine this week. Cheers!

I posted a picture of my Pinot noire grapes changing colour from green to black Peemick.

Thanks for the picture. I think I might remove some of my leaves as you have done to help with the ripening process.

I have no idea Freddie12 why yours have gone the opposite way to mine...have they ripened more this year or something like that?
