A most enjoyable story - thanks for posting it.
I really like reading news from the American heartland about this kind of thing - especially, however, when it centers on the new hybrids being developed, primarily in Minnesota, that enable viticulture to take place naturally in the continental climate encountered across much of the Midwest. In so far as there are grapes that do well in these conditions, it has always been my position to champion their development and propagation. But if someone has a suitable microclimate for vinifera, then that's good too.
