Reply to comment by Elfere in TIL Europe's wine owes its existence to the grafting of vines to American grape root stock that weren't vulnerable to a species of aphid that was destined to wipe the industry out. by salton

Phylloxera didn’t make it to much of the major SA wine growing areas like Chile where they were mostly isolated (Chile is the only wine-growing region in the world that never had a phylloxera outbreak.) Same is true in Australia where most of the vineyards still have their original root stocks (I believe it’s around 70%.) It’s not that these stocks were immune to it like the NA root stocks, it just never made it there. If it did surface in these regions, they would have to replace the stocks, but that hasn’t been necessary (yet.)
