Hey, syd, I posted something but think it got lost in the shuffle somehow. Btw, I really enjoy Old Potrero -- a mini revolution in American Whiskey, and have given it an extensive review in the Dram of the Day on my blog <www.maltresistance.blogspot.com>
Check it out!
Old Potrero has two offerings which purport to imitate 19th and 19th century amreican whisky, respectively.
In the same vein, perhaps more of a gimmick, a bourbon called "Bulleit' 'the bourbon that tamed the west' is on shelves in the U.S.
Hope this helps!
