Here's a detailed explanation of the difference, if there is any, between bourbon and Tennessee whiskey. It explains it in much better detail than I can and ......... it's written by a woman who is a bourbon enthusiast. Whether she is a lady or not I cannot say.

Tennessee whiskey basically is bourbon that has been filtered, before going into aging casks, through sugar maple charcoal.

May God bless America and those who defend her.
