Bob, many thanks for this TN.
Vidal makes what I consider to be some of our best "everyday" white table wine in Ontario; this despite the fact that as a variety, it is of course most famous as one of our icewine grapes.
I've had some truly fine dry Vidal from Magnotta - their '00 in particular threw masses of tartrate crystals and if any white could be said to have "crystalline acidity", that one did.
Vidal is extremely versatile for us here in Ontario because it successfully runs the gamut from crisp dry table wines, to off-dry, to late-harvest and finally, icewine. It's hardy and productive and a good match for our terroir.
