I know it's a bit hotter where I am than Sonoita but I will say that I personally have preferred some of the cabs over some of the Grenache and Sangiovese wines I've had from Sonoita. I don't know if I've tried a Mourvedre from Arizona before. I imagine the quality is not as good but I have heard of people having luck growing Cabernet Sauvignon grapes even up near Phoenix.Ah, cool yeah no I meant where we are were the only winery.
I am interested to see how your vineyard goes, I would strongly suggest Spanish grape varietals or Italian to deal with the heat and get a good wine. As cab does not like heat I would look more along the lines of Grenache or Mourvèdre or something like that though Sangiovese is also a good pick.
I see that Double A only has 5BB rootstock with the Mourvedre. Is that suitable for this area? I'm also curious if Syrah would grow well in my climate or if the heat would be too much for it? Thanks for any advice or suggestions
