Jeff Chorniak grows Cabernet Franc vines in a suburban backyard in
Toronto. He began by growing them in pots and treating them like
bonsai trees. At some point he did away with the soil and his bonsai
vineyard became a hydroponic vineyard. I'm having trouble with the url
to his current site:

His old site, featuring his bonsai vineyard, is still up at:

He inspired me to grow grape vines in pots in my backyard (a suburb of
Seattle, WA, USA). I can tell you that it does work, and it's worth
considering if you have limited space (or bad soil).
