Well it's your lucky day because that WAS a list of the 10 most expensive whiskys.  Not a single one of those is a "whiskey".  Only whiskey produced in the US and Ireland is called "whiskey".  All others are "whisky".  The items on this particular list are all Scotch whisky.  9 of them are single malt scotch, and the Chivas Regal is blended scotch whisky.
