I have an acre of Frontenac and Sabrevois vines. The vines are anywhere from 1 to 2 years of age. Many of the leaves are showing signs of shriveling up (curling up) and have a bumpy texture. Whatever I have is not phylloxera. I can send you pictures. Many of the vines were decimated by deer last year. The vines appear to be growing but the leaves look funny. I can’t tell what it is. Do you know?

The leaves in the photo appear to have been damaged by herbicide. If herbicide drift has occurred in your area, grapes will be among the first to show the effects.
