Uh, I just googled your table grape (Girgentina), Fish, and it turns out
to be a wine grape from Malta.

Cabs and Syrahs are every where, but who do you know that makes a
Girgentina?

Malta
Climate
The climate is Mediterranean (Köppen climate classification Csa) /
Subtropical [58][59], with mild, rainy winters and hot, dry summers.

Syrah/Shiraz (region 3) may do OK where you are, but a Cab (region 2)
would struggle. You might try Barbera, Nebbiolo (used to make Barolo),
or Sangiovese (heavey tannic wines like Brunelo, or light fruity wines).
The is also the indigenous red grape of Mallta the Gellewza which
produces medium bodied easy drinking red wines and award winning roses.

Head pruning under these conditions is a good thing because it shades
the grapes, helping to prevent sunburn, which can then be infected with
mold.

Cane pruning or cordon is best for areas that are cool, and you want the
circulation of air, and penetration of sunlight to remove any moisture
that may collect in the canopy.

I'd suggest that you keep an experimental plot of these grapes, and
prune them back to 24 buds. If you are too lazy to prune, you might look
into getting a couple of goats;O)
