What is this?

[Vern]

Found this on a Frontenac Blanc today. Any idea what it is.

Possibly a type of gall. I’d get rid of it

Cut it out way back from the vines and burn it or dispose in the trash. Don't throw it down on the ground. Wear disposiible gloves if you can.

Send the picture to your state viticulture expert or the closest you have.

I cut it off and threw in garbage. Thanks for input.
