That’s great. We have been trying to grow grapes for 4 years now. The first year was a good crop, but the coons got there first. Then there was the summer of the drought, and berries and grapes have been way less than prolific since then.
The secret is in late winter pruning, with snow on the ground.
Around here, grapes are grown in full sun on horizontal wires attatched to heavy stakes, especiallyon the ends (with dead-man ties).
Due to topography and glacial debris , most advantageous is a North-south orientation so that the entire grape plant receives maximum sunlight
as lower growing branches will mature later since they are somewhat shaded by the upper arms of the kniffin system .
The recommended technique here is called " Four Cane Kniffin" system .

Well, let me tell you about grapes! We bought two seedless varieties and planted on wires, pruned according to Sunset Western Gardener directions...did it for four years, grapes came and they had SEEDS!
I have 4 arbor gates into the garden, planted seedless grapes, three years later...you guessed it...they have SEEDS! All the varieties and labels (colorful) were for seedless. How can different growers sell me mislabeled plants? Anybody else have that problem?
I’m going to plant concord grapes this spring...I know they’re work, but they are so good and so tasty....and easy, I should add that, once you get them established...
