The best ice wein I have tasted actually came from Canada (I suppose there's no shortage of frost there) As a 'pudding wine' it is as good as a Sauternes anyday and lovely with a really ripe mature Stilton (sorry wrong thread - I think that was the cheese course one)
There are excellent (and relatively inexpensive) varietal wines available (at least over here) besides the ubiqitous cabernets/chardonnays. My own favourite is the Burgundian Pinot Noir (also makes excellent fizz) but for a change try the lesser known Carignan - excellent with Mediterranean food.
