Grape Baco 1 seems to grow well in my heavy clay soil. I did also have a Madeleine Angevine, but it kept getting really mildewy and horrid looking, so I took it out.
It's taken me about 8 years of messing about to get it producing a good crop - it started in the back garden, got moved from shady side to sunny side, and then got moved to its current position about 4 years ago, where it has flourished - back of shed, facing almost south, in full sun. I learned a fair bit about them at college, so hopefully my winter pruning will be better this year than it has been in the past. And I'll try not to shift it any more. :-[
