Well, I wasn't sure. Maybe he is just a fan of Dewars. Figured I'd leave it to someone else to decide.
I find most from canada tastes like vodka with sugar and caramel color. I think most canadian whiskey is mixing whiskey for mixed drinks... which may explain why it mixes so well. The Crown isn't too bad by itself though.
Some people judge whiskey by the degree of hangover they have the next day. Canadian is clean and doesn't leave you feeling as much like crap as Jim Beam would.
