Black (90 proof) is stronger than Crown Royal (80 proof), and, as it's name suggests, is darker in color -- thanks to the added oak flavor. The whiskey is a little sweet, with notes of maple and vanilla. And, man, is it smooth. A couple Fridays ago, at the end of the workday, a few of us at the office enjoyed a drink of Black, neat. We were all impressed by how easy it went down.
