im not a wine expert, my father is an amateur wine maker and he has some different grape types and that is one of them

the slip skin is correct

i dont know what PNW, if you mean climate know that plants can survive in places where they arent expected to.

you might get less yield compared to the optimal place (or sweetness) but it might work even out of the optimal places

i am not even an amateur wine maker so take that with a pinch of cocaine 😅
