Thomas Jefferson was the first American to try to raise European Wine Grapes in the US, they all died out within a few years of being planted. The reason for this is American Grapes are generally immune to Phyllozera, while it is a killer of European Grapes. Furthermore Phylloxera is carried in the roots of American Grapes thus when Jefferson brought his European Wine Grapes to the US, he exposed them to Phylloxera and the grapes subsequent died. It was unknown at the time but Phylloxera was the cause. In the 1860s American Grapes were introduced into Europe and brought Phylloxera with them. This quickly spread to European Grapes and you almost had all of the wine making grapes in Europe die out. The solution was to graft European Grapes onto American Grape Roots. Thus European Grapes today have a European Top, and American roots.
Thus my comment on the roots, is is American Roots or European Roots? If American Roots not a problem, if European Roots, if you are in an area where Phylloxera exist it will die. Phylloxera exists in the Eastern US (Where it is Native), Europe (where it was introduced in 1863), Australia (Where it was introduced in 1877), California (Where it was introduced, through it is unknown when). Phylloxera does NOT seem to exist in Chile, Washington State or most of Australia (Excluding Victoria (Where it clearly does exist), New South Wales and maybe Queensland, where it might exist).
