I just happened to buy an '86 Renaissance Cabernet Sauvignon Reserve. More curious than ever to try a real cult wine.
There are several own rooted vineyards here in Oregon, not all predating the discovery of phylloxera. I have no definitive knowledge on the subject, but I'm aware that sandy soils are less hospitable to lice. I've heard winter cold can slow them but obviously that's no cure. I think isolation is the key for most healthy own rooted sites. I wouldn't think oxygen would be an issue at all, unless you were well above where vines could grow. Even then, I can imagine the only things that do survive at high altitude are bugs, but what do I know.
