[quote name='bleak']Johnny Walker 'Black Label' is Scotch not Whiskey.[/QUOTE]
'Scotch' is a type of Whiskey made in Scotland. Another type of Whiskey would be Bourbon, which is made in Kentucky. Any Whiskey not made in Scotland or Kentucky is usually just called Whiskey.
Johnny Walker is a blended Scotch Whiskey, it wouldn't be inappropriate to call it either a whiskey or a scotch.
Unless you are talking to an actual Scotsman, then there's no chance they will listen to reason, best to kick em in the jacobs and run.
