Insider knowledge: Caol Ila 25 Year Old (2010 Release) whisky is named whisky by virtue of the fact it's from Scotland. If distilled in America the spelling would be Caol Ila 25 Year Old (2010 Release) whiskey, as opposed to whisky.
I had one of these in January with the state stamp from 2008. Rally great whisky and luxurious-looking presentation. Can't wait to be 25 yo again :)
