Except that black and tan entered American and British English usage in the 1890s as a name for the drink before it became associated with the Black and Tans in the 1920s.

Granted, I wouldn’t use it in reference to the drink in Ireland and there may be some argument against its usage in the modern UK. But this is a rare case where we Americans haven’t coined an offensive phrase for something (Irish Car Bomb cancels out this small victory).

I’d make my 9/11 as a smoked double Manhattan in a chilled collins glass made with Russell’s Single Reserve 110-proof Bourbon with a twist of lemon.
