Grapevine in shade

[Mango Stein]

Is it possible to ripen grapes if the bunches are in the shade and just the leaves are getting sun from above? I have a narrow area blocked off from morning and afternoon sun. So just sunlight from above would hit the overhead trellis. But it would still be a good number of hours.

My most productive grape (black Spanish) is in bright shade almost all day, but I tried the same thing with some muscadines and they don't produce. Give it a shot. D

The main problem will be production and deseases. But the way you describe it, it should be fine. the fruit doesnt need too much sun, only the leaves
