however you spell it, orange lable, you know the one....
It's Veuve Clicquot
I love good wine, but I'm not too big on champagne. If you are going to go with a nice bottle you can't go wrong with this one. In my opinion, the really high price vintage champagnes aren't that much better. The Vueve Clicquot yellow label is around $45 a bottle.
I've tried a couple of different ice wines and they were both good.....in a sweet liquor sort of way. Unfortunately, I don't remember the names. When in doubt, go by price. It's not foolproof, but often a good indication as to quality and taste.
Anything from the niagara region is good for canadian icewine. Most summers we get long hot humid weather (great for the grapes) and then a quick snap of cold that will be good for the icewine. I wouldn't get any of the two or three most recent vintages though, the weather wasn't that great in the growing season (but anything around 2001 would be good.)
Pelee island winery makes a respectable icewine, and they're gaining status so you may be able to find them outside the region (they're cheap, which is why I would recommend them).
As for champagne, my best friend just helped me move my sister to a new house and he gave her a magnum of 1985 Dom Perignon as a housewarming gift. It was quite nice.
