I have a quart bottle of "Seagram's Crown Royal Fine De Luxe Blended Canadian Whisky". It was bought in Canada, and the import seal is still intact and says 1968.I have no liquor expertise whatsoever, so hopefully this isn't a silly question! Thanks!

drink it

Unlike wine, whisky and other spirits don't continue to age once they're bottled. So the whisky in your 40-year-old bottle will probably taste pretty much the same as a 3-year-old whisky (or however old the label says it is). You could check a local liquor specializing in whiskies to see if it's worth anything (I'd say ebay too, but I'm not sure they sell liquor there). I doubt it would be, and if it's not, go ahead and open it up and give it a taste.

me well i'd just drink it...

If it is dated then some one may well be interested in it for that.It is going to be 50 years old next. Some ones idea of a great Golden wedding anniversary present perhaps. (You just missed the 40).Put it in to an auction, that is the best way to discover it's worth. Make sure you put a reserve on it though. Granted whiskey does not alter in flavour, but not every one knows that and some one may think that it does.
